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.
On fixing carbon frames:
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,
Questions about inspecting carbon forks for safety, trying Wippermann chains with Campy 10-speed systems and using Shimano MTB derailleurs with 10-speed road systems. What to do? I'm low on funds and that's the main reason I haven't replaced them as yet. I will add there are no stress fractures or noticeable wear.
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,

More tire talkDear Lennard,I really enjoyed your recent wet-road tire discussion with Tom Petrie and Alberto De Gioannini. Just the topic I was looking for, but I'm still a little confused. I thought the cord compound made a big difference and it wasn't mentioned at all. I recall racing in the rain in a crit next to a friend who was running cotton-cord sew up tires as opposed to my silks. While we'd been comparable in bike handling otherwise, I found myself nearly sideways in corners while hewent around like on a rail. We'd pumped our tires to comparable pressures.I'm taking a group over for
