    monocoque carbon fiber, hand-finished, light weight


    mold hasn't changed since bike's inception in 1989 so the steering angle isn't suspension-friendly; how many large rocks will kick up into the carbon fiber downtube before structural integrity is compromised ? ?

    For those who are familiar with the ecstasy of carbon fiber this frameset does not disappoint. Small bump forces are all but absorbed and forgotten without much loss of momentum (as opposed to aluminum) Stutter bumps can be hammered through without necessitating dental work. The weight of the bike is exceptionally low - the bike pedals up to speed quite easily. Workmanship seems quite thorough and the blue paint fade into exposed carbon is a nice touch. Where the bike flails (literally ) is in the handling department. Due to short top tube and "old school" geometry, steering inputs can be expected to affect the bike's direction somewhere about a second later. This affect can be minimalized by running the boazabeana x or similar sub 400 gram tire. Don't even bother running anything bigger than a 1.95 unless you thrive on funk. The sid absolutely does not help the front end situation as the frame will "give" slightly in hard cornering. The combination of these two noodles is alarming to all but the most experienced riders. If superlight tires are used, the bike does accelerate very well and is manageable from a handling standpont. Moving on to the mismatched front derailleur/big ring combo: xtr e-type goes with a 46t chainring, and xt big ring is 44. Although this 2-tooth difference only amounts to a couple of mm in clearance,(3-4 mm instead of 1-2mm) the e-type fder cannot be moved up or down, and this results in losing the chain off the big ring almost every time, even when overcompensated for with the limit screw. Now, I like to ride my bike - not get off every five minutes to put the chain back on. By the way, when the factory mechanic was notified of this problem, he denied any compatibility issues curtly, even though two identical drivetrain explosions occurred in the same event. Sooo, change the front derailleur. But what would the chain do to the BB if it weren't e-type. OK, so change to a 46T chainring. If I only knew that before... Now that were hitting on the point of carbon's durability, I'm just not sure if I want to find out how many rocks it takes to raise a question mark about structural integrity of the downtube. BL: if you're a carbon aficianado with handling skills, deep pockets, and can't get enough funk, this is the one for you.
