Update: the Thorn is sold and I'll order the 56cm LHT - the standover height is about 1/4" taller than the Thorn, so there's nothing in it. The LBS quoted for Hamsterskins, so they'll have to be changed - I think I might also have the new Deore chainset rather than VTiagra, since 48 x 12 is quite enough for me, and it would then definitely all work in terms of chainline. I insisted on handbuilt wheels, which will be Deore hubs on Mavic Open Sport rims with DT Comp spokes, done in the shop. Dura-Ace bar-end shifters.
Does everyone get them in green?
