Can I get a Trek Madone seatcap with more setback?

Dear Readers,
I’m in the Denver airport about to fly to Italy for the Giro d’Italia. I have enjoyed a lot of the feedback from a few recent columns, and I thought you might as well. Next time you hear from me will be from the Giro, so look for some cool bikes for the team time trial soon.

Dear Lennard,
In your Earth Day column there was a question about a cracked carbon frame. Since it is a save the earth day of posting I thought I would ask about the possibility of repairing a cracked carbon frame (small crack obviously). Since you can buy epoxy and carbon, would it be possible to repair a carbon frame? It would be ugly but would it be rideable?
Scott Dear Scott,

Dear Lennard, I am considering storing my new full suspension bike using a vertical type rack that stores a single bike hanging vertically from the wheel. I was wondering if that could cause any damage to either suspension, front or rear. Does it make sense to hang the bike from the rear wheel? Nir Dear Nir, Hanging it from the front or rear wheel will not hurt it unless either of your shocks leak oil through the upper seals. In that case, hanging it could still be a good thing, because it will alert you to the problem and motivate you to fix it. Lennard

Why does my bike shimmy at high speed?

TorqueDear Lennard,I recently purchased my first full carbon bike, absolutely love it. Yet, I'm scared of over-torquing the seatpost clamp. Is there a torque wrench you could recommend that works on Allen wrenches? What's the worst that happens, the seatpost clamp needs replacing or I have this fear of the actual seat tube deforming, I'm not doing the Samsonite luggage monkey torque on it, but "hand tighten" is just too open to quantify.ThomasDear Thomas,First of all, carbon frames generally have a separate band clamp to tighten the seatpost, and, yes, the worst that can happen,

How can I re-finish my titanium frame?

Do cranks flex, or is it the bottom bracket and frame?

What is the best seatpost material for a titanium frame?

Oscar Freire sprinted past Robbie McEwen and Erik Zabel to win stage two aboard the mount that has brought so many victories to Mapei and Rabobank. He was riding a Shimano Dura-Ace equipped Colnago C40, the 2.5-pound frame that won Paris-Roubaix five times between 1995 and 2000. But it is not just another bonded carbon frame, since Colnago’s construction methods C40 are unique and analogous to its method of constructing steel frames. Integral to the C40 are one-piece molded, hand-finished carbon lugs that eliminate the bonding problems and weight of aluminum lugs and are stronger,

Does increased fork rake or rider position affect high-speed shimmy?
