    Core Sample

    1st place Vultures Knob Groovy Series #2

    I have always been carless about having bar plugs on my bike, but I am now converted. My front wheel became stuck in a rut and I crashed at my max speed for the course, 31.5 mph. In the fray, the bar punched me right in the throat. Thankfully, it just hurt. I can only imagine the gore of being core sampled like a potato when it’s been stabbed with a straw.

    This also makes me think that I will try holding on to the bars for a little longer the next time that I have a big crash. In the past, I have always let go early to try escaping the fray. Depending on the situation, it might be a good idea to try riding out the crash. By hanging on to it a little better, I could probably put the bike between the ground and myself. This is something to consider if the bike is going down sideways, but I am still going to bail out in a front-end collision.


    In other news, while at the race I won a pair of custom carbon fiber insoles that are supposed to increase my power transfer. I will let you know how they work when they arrive.

    OMBC #4 The Wilds

    1st place

    The race was about 26 miles long and I had not seen anyone for the last 8 miles. When at the top of a short climb, I looked back and saw the second place rider coming through the trees only 15 seconds behind me. Panicking a bit, I immediately started riding harder and planning the rest of the race. My computer said we were 5 miles from the finish. This is the first time that I have raced the person in second place, but he already came with a reputation and a resume including one of the hardest races in PA.

    At this point in the race, I had just finished consuming the last of my food and water making this the perfect time to take the pace to the next level. It was really the only option, because I sure as hell didn’t want to loose a sprint to the finish against a strong roadie. I started to ride as hard as I could from that point on. If I could at least keep the 15 second lead, that might be enough for me to win the sprint at the end. All of my gauges and sensors were firmly pegged in the red zone and my jaw ached a bit, which only happens when I ride hard.

    At the end of the race, I watched my back as I climbed the final hill and covered the remaining yards to the finish line.  I thought for sure that he had been working just as hard as I had and that this was going to be an all out battle, but he wasn’t there. All of the paranoid scenarios that had played out in my head during the last miles could now go back into hiding. From that point in the race 5 miles earlier where I had seen him to the finish, I was able to put a 2-minute lead on him. What a relief.

    OMBC 2 Mountwood WV

    Rain fell throughout the race eventually turning the West Virginia trails once hard surface into a sloppy pudding of mud, rocks, and wet roots. I felt very good at this race but was unable to keep Ben's pace in the worsening conditions of the final lap. In the last 4 miles, I slid from his wheel to about 1 minute behind him. I think his 29” wheels and knobbier tires gave him a distinct advantage on the heavily ridden surface of the trail.

    During the first half of the race, the GT Marathon gave me a solid advantage over the competition. The ability to ride with impunity over mud covered log bridges and through rock gardens gave me huge speed gains but I held back from taking the lead, as I got lost at this race last year. Gunnar Shogren and I had taken an extra 8-mile tour of the course. When we crossed the finish line, we thought we had come in 1st and 2nd only to find out that we were in 25th and 26th position. This year I had decided in advance to wait until the end to strike, but as chance would have it that did not happen. I finished this race in second place.

    OMBC 2 Vultures Knob

    The GT Marathon rode very nicely. This being the first time that I have had a chance to ride the bike off-road; I was very interested in having some alone time with it. Thanks to some excellent training, I was able to experiment with the bike from the middle of the race on. During each lap, I picked new lines, tried climbing seated vs. standing, and tested the limit of traction. Coming from a hard tail, I had much more grip than I've been accustomed to.

    Most ambivalent moment: I had been riding all of the corners hard, drifting under power, really getting a feel for the bike, that sort of thing. Well, I end up throwing a bunch of rocks over the edge of the corner and down the hill, which intern shower a lapped rider and his bike. I finished first, about 5 minutes ahead of the next guy. Due entirely to this super smooth GT Marathon.

    I capped that off with pizza from Angelo's "Bishop".

    Drag

    Here are some numbers that I have run on the GT Marathon and a few other bikes for comparison. The numbers don’t lie, this thing is a XC racing machine. When the Marathon is in the large chain ring, the rider faces a 2% drag on the chain line at 0 travel and 4.5% at half travel. In the middle chain ring, the drag increases to 10% at initial travel and 11.3% at half. These numbers are very good when compared to other full suspension designs. For instance, this bike averages 8% drag. The VPP design averages 28.1% drag, and the FSR, 9%.

    Carbon Fiber Brake Rotor

    Below is an experimental carbon fiber brake rotor. I saw one years ago and wondered why I hadn’t seen another since. The answer, because they don’t work for very long.



    I thought that this might happen, but I was interested in seeing how long it would take. Honestly, I hoped it would last a month or two. I didn’t think that it could be such a failure.

    In the initial test, I tried a few 20 mph stops. The grip increased with each stop until #5. During which, a lump began to form in the break feel. Soon after a hunk of brake surface tore away from the disk. When I looked half of the surface was just hanging.

    I think the problem was heat building up in the disk during the hard stops. It’s my guess that the heat combined with the high torsional load caused the epoxy to weaken. In other experiments I have done heat has played a role in failures. The question moving forward is how close to the heat can this epoxy be before it is affected. For now though, my carbon fiber doesn’t really have any place as the actually braking surface, but it could be used to support a brake surface.

    Ray's Factory Riders

    The Factory Riders website is now open. If you haven’t taken a look at it head over now. It’s growing by the minute. The imagineers at Ray’s have been hard at work developing it for more than a year and the first rollout is running.



    GT

    I will be riding for GT in 2009. It is an opportunity that will take me farther than any I have had in the past. In addition, my role will change slightly. With GT I will act as more of a company man, doing more promotion, events, and demos. The change comes at a perfect point, giving me more time to develop as a pro level racer. This approach will also help GT remind the racing public that they can still make a super bike.

    The situation is puzzling. It has been 5 years since I have seen a GT under a privateer racer and 8 years since anyone I know (Todd) has purchased one. I have had the chance to ride a few over the years and they have always been impressive. In fact, I once owned a full XTR Team LTS, which was the most amazing bike I had ever ridden. I bought the bike second hand from Alex for $600 and raced it many times. No bike before or since has climbed as well and this might seem strange, but none have looked as good.

    If you haven’t seen them, this years bikes look hot, something I worry about. They offered me the choice of a carbon Zaskar or Marathon. Each is amazingly well built and stunning to look at. I had to consider the evolution of my riding style in the choice. Over the years, things have changed making the clear choice for me the Marathon. Getting power to the ground has been an issue with my current strategy, so that puts the Zaskar out of the question. I have talked to the engineers at GT and they back up my thoughts making this the clear choice for me.

    Long-term review

    of the Manitou Minute MRD Absolute

    3.2 pounds, 100mm of travel, 32mm stanchions

    The following is a review of this fork from my point of view. This is the final review for the first Manitou that I have ridden since swearing never to ride one again about five years ago. I have owned three Manitou forks prior to this one, and all have broken. First, the crown on my EFC cracked on either side of the steer tube. Then, I had two Manitou Mach 5 SX forks break. Number 1 snapped jumping down some stairs and the stanchion tubes on number 2 broke off just below the crown while trail riding.

    I could tell immediately upon seeing the new fork that this wasn’t going to be the issue. Manitou is hardly the same company that it used to be. Gone are the soft CNC’d crowns, the plastic preload adjusters, and the squirmy dropouts. First, this fork is built on 32mm stanchions, which sets it apart from the 28mm crowd. It’s an entire order of magnitude stiffer than a 28mm fork.

     Ideally, this thing should work all year without maintenance, have 100+mm of smooth travel, and be light. The reality wasn’t far off the mark.

    I have put about four thousand miles on this fork in a mix of XC racing, 24 Hour endurance, trials, and jumping at Ray’s. The bike frame supporting this fork broke twice; all the while, this thing continued unfazed. In fact, it works so well that I never think of it. That’s not something that I can say about others that I’ve ridden. The construction of the fork is incredible.

    The tag line of this fork should be “Set it and forget it”. Give the rebound knob at the bottom a couple clicks and you’re done. I’m not a fan of lock outs, platform, or compression dampening but this fork does have a very nice platform system.  It sounds very mechanical when it’s working and seems like it does the trick. I’ve found that I only fiddle with the lockout knob when I’m riding for fun. I doubt anyone switches this thing on in the middle of an endurance race.

    It is smoother and stiffer than the 2006 Fox F100 RL, and after four thousand miles, it’s just starting to break-in. It is without question the best fork that Manitou has ever made.

    AS/400

    At work I have been building an industry desk. I’m working with middle market manufacturers that have revenues between 50 and 200 million dollars per year. This size company can support the technology that I focus on and pay the fee that we charge for our services. I spend a lot of time looking for IBM AS/400  (iSeries) mini mainframe instillations running JD Edwards enterprise resource planning software or the programmer analysts that works on the systems. The AS/400 is or was the backbone for most manufacturers. Many companies are moving to network based data systems, but the 400 still holds a strong market share in the slower to change manufacturing environment. They are also popular in the insurance industry. The AS/400’s ability to crunch enormous amounts of data makes it perfect for referencing data points in a huge national directory for every transaction made.

    I spend a lot of time looking for clues that a company will have an AS/400. A clue may come in the form of a software package, style of programming code (RPG 3, 4, and COBOL) or industry. Clues like these lead to finding hiring managers and employees that have specific needs or the right professional background. From this point, I market candidates to the hiring managers with the intent of landing a job order. Adversely, I can recruit employees from the company to export to other companies.

    Moving employees from one company to another or marketing one exceptional employee to several companies is the name of the game. In doing this, it is hard to avoid learning all of the latest technology, news, and rumors within the market segment.  All of the industry data comes in handy when convincing someone to make a major change in career paths. This is all the more important in a shrinking industry segment filled with an older population of programmers, more than 80% of which have 10+ years of experience. However, for as large a decision as this seems to be, I am regularly surprised at how freely people with great jobs jump in with both feet. My developing ability to create the perception of greener pastures is becoming an increasingly important skill.

    AMBC Greenbrier

    I raced at the Greenbrier Challenge in Maryland this weekend. It was a great race for me because it validated a lot of training that I have been doing. I have had a rough go in the last two races, but I am pretty sure now that my problems were out of my control. As everyone may know I was misdirected by an uniformed course martial at the Mountwood OMBC race two weeks ago. Gunnar Shogren and I ended up riding six extra miles. Surprisingly, we didn't finish last.

    This weekend at the Greenbrier Challenge was great. I started the race riding pretty hard and quickly got away from the rest of the semi pro pack. Within a couple of miles I began to reel in struggling pro riders. About 10 min into the race Chris Eatough who had been separated from the pro pack by a flat tire ended up behind me. We rode together for the next three laps taking turns pulling, admittedly he more than I. He is much better at passing lapped riders than I am. I'm just not verbal enough when I'm racing. At one point while pulling, I caught a slower pro rider and yelled "rider up" to which he replied "left or right". I couldn't think, so I said "I don't care". By this point I was practically on top of him, so I passed in the rough. Chris Eatough plans this out much better.

    At this point I should mention the true performer here, my bike. It rode so smoothly over the thousands of rocks that littered the trail. The combination that I have is amazing. The Manitou MRD Absolute was so smooth that I didn't think about it at any point during the race. It feels bottomless and steers with such precision that it requires no extra thought. In addition the Mongoose frame is so light and compliant that climbing on it seemed effortless.

    At about the middle of my last lap I had worked my way to 3rd in the pro class with a 3+ min lead on the next guy in the semi pro class. I wish that I could say that it continued to work out like this but it didn't. A broken spoke became tangled in my rear derailleur tearing it off the frame. On the spot I tried to break the chain hoping to shorten it and remove the rear derailleur but I couldn't make it happen. I ran the last three miles finishing in 11th place. Not what I had hoped for, but good enough to qualify for nationals.

    High Water

    Today my girlfriend and I took a walk through the valley near my house to get a firsthand look at the high river, which had closed the roadway. A cop had been waiting in this area earlier when I rolled through on my bike. He yelled at me as though my intention was to ride through 100 yards of near freezing water.

    On our way past Big Met golf course, we heard a high pitched scream. The scream sounded like that of a bunch of twelve-year-old boys horsing around. It could have been someone in the water, but it wasn’t possible. The river isn’t the type to just carry someone away. For that, someone would have had to wade out ten to fifteen feet into the quick current. This time of year, that alone would have been crazy. The water is hardly above freezing.

    We heard the sound again at the top of the hill and it pulled us down. It was coming from an area close to the water’s edge. The yell came, “please help me”. This time it was coming from the water or the opposite bank. I couldn’t tell, but I was rushing toward it. I saw a figure in the water about twenty feet from the water’s edge, about four feet into the fast moving water. From my left came an officer. The same one from earlier, but he was looking too far up stream. I yelled to him, and saw over his shoulder to the Fairview Park fire engine and two other cop cars plowing through the water on the submerged roadway.

    I have heard on a number of memorable occasions that I am too quick to draw large conclusions from small amounts of data. Previously, this sense or logic had been relatively flawless. I had known from a few characteristics if someone was employable, violent, a user, or fishing for information. It occurred to me at that moment the system was flawed. My method of thinking through the situation left out an important factor.

    Hearing the scream at the top of the hill, it would have made sense for a young boy to get too close to the water’s edge in the absence of the officer. The area where the road meets the water is a perfect place to fool around, that’s why we had come. The water is just too slow. It is sitting on the road but it isn’t moving anywhere. I had jumped to a conclusion based on a story that my mind invented.

    Following my direction, a firefighter with a rope rushed into the water without tying off. The cop yelled at him but cut his effort short of getting wet. Before he could reach her, she let go of the tree she had been holding onto the entire time, but the fireman jumped and grabbed her at the last moment. Having not tied off he quickly became stuck in the current with the woman, but retained enough strength in the icy water to catch a line from shore. As he brought her toward shore, she struggled against him to let her go. She was in her late 40’s with a short hair cut and baggy shirt. Her pants had been torn way by the current.

    As she was carried away, he said that she had been trying to kill herself.

    It didn’t make sense, and now it makes sense that it didn’t make sense. Killing yourself is crazy. No sane person would have gotten himself or herself into that situation. Never the less, in that instant the X factor didn’t occur to me, and I jumped to the wrong conclusion.

    A top performer

    Reviewing a bike like the Mongoose Meteore requires a baseline of knowledge. Sure, it is one hell of a ride for someone moving up from a department store bike, but how does it really compare and what should you look for. What is different about this bike when compared to other bikes in the upper price range? What has Mongoose learnt from more than thirty years in the biz? Moreover, after selling so many bikes through department stores like Dicks sports, do they still have what it takes to make a top performer?

     

    Part 1

     

    How do you even know what a good bike is when you see one? What makes one bike better than another. First, I don’t care about cranks, shifters, post, derailleurs, bar, stem, cassette, or peddles. What makes a bike perform is the frame, fork, and wheels. I hesitate to even add wheels to the list of variables because having light wheels at this price point is a given. Everything else just falls in line once these decisions solidify.

     

    On its own, the frame is simple, but we are going to ask a lot of it. It must be just strong enough to last under the weight of “the” rider. There is no need for an overly built frame if your goal is to race cross-country. At this point extra frame weight amounts to sloppy production, poor engineering, or the company being overly cautious. The frame must also contain a blend of handling characteristics that will make it safer, more fun, or quirky to ride.

     

    Precise handling characteristics come from frame geometry. Quick handling often comes from a tall bottom bracket and short chain stays. However, quick handling can also come from a shorter overall wheelbase and steeper head angles. A bike that has a long wheelbase with a tall bottom bracket and short chain stays is one that will require more body movements to control. A tall bottom bracket will raise the riders roll center. This puts more of an emphasis on the rider’s body movements. A low bottom bracket height with a shorter overall wheelbase, often accompanied by a longer rear triangle will tend to put the rider at the whim of the machine. This will cause the rider to steer through a difficult section rather than lean or twist.

     

    The frame must also be compliant. Someone could argue that a flex free aluminum frame would pay dividends at the end of a race by transferring power more accurately from the rider to the ground, but that argument no longer carries any weight. In the 90’s is was true that dulling the ride of a bike by making the frame more compliant and often heavier was poor choice compared to a ridged rival. Today, lightweight frames that dampen vibration while remaining lively are a far better choice for racing. There is also evidence that a forgiving frame will last longer than its ridged counter part by more effectively dealing with stress.

     

    To come in part 2, suspension forks and practical application

    New bike

    I just took the first ride on my new Mongoose Meteore. The bike isn’t quite ready for a full test, but I couldn’t wait. Still missing are the wheels and front derailleur that should be here by the 17th. On my first ride, I noticed that it is quite a bit different from the GF Ziggurat. It is still difficult to gauge the bike as a whole because I’m getting it dialed in.  However, I noticed the smoothness of the fork. The Manitou MRD is smoother and stiffer than any Fox fork I have tried. It’s simple dampening valve is very light and superbly effective. I noticed something that will require a second look. The platform-dampening valve makes an audible sound when it breaks through.

    Despair

    It could just be the cabin fever, but the news of Burger King taking Mozzarella sticks off the menu has hit me hard. I find it ironic that Burger King would have an advertising campaign called the “Whopper Freak-out”, wherein a hidden camera catches customers freaking out to news that the sandwich has been removed from the menu, only to do it for real. This is real. The Mozzarella sticks are gone, and the employees don’t know when they will be back, if ever. Everyone is really shaken up.

    On Thursday, when I pulled into the drive-through my eyes scanned the dollar menu not finding them. The menu showed no signs of tampering; it was as if they never existed. I asked, “Do you still have Mozzarella sticks”? No, I heard in return. “We no longer carry them”. You know, I hadn’t considered how much I loved the King’s Mozzarella sticks until they were gone. Being able to get them at any time of the day is something that I have come to count on. It’s hard to put a price on that kind of convenience.

    Now comes the hard part, moving on. I am sure that someone else sells them. Maybe they will not be as cheap or as easy to get, but someone will have them. Just as you become comfortable with something, they take it from you. If they were not still selling the Whopper, I probably would not go back.

    A new sponsor

    IMG_3688 

    I have a new sponsor, and its name is MANITOU.

    This season I will be doing two long-term tests. The first will be the Manitou Minute MRD Absolute. The fork is new fork is all new in 2008. It still has 100mm of travel, but now it weighs 3.2 lbs. It has the weight of a SID with the stiffness of a Fox.

    The second long term shock test that I will be doing is the R7 MRD Absolute. It too is all new for 2008 and comes in 80mm or 100mm of travel. The difference is the shock weighs 2.76 lbs. It shares the same internal configuration as the Minute but uses 28mm upper tubes instead of 32mm and a smaller oil bath to shed the weight. This fork weighs barely a pound more than the lightest rigid fork and has the plushness of a Minute.
