I am much more of a tinkerer than a restorer and have modified a number of bikes to meet my needs. This may be my best:

-- gravel grinder
-- Russian/Dutch Ti frame
-- Deore XT RD and FD
-- Gossamer 50/34 crank
-- DA barend shifter
-- Thompson nosetback seat post
-- Tektro Brake Levers
-- Shimano cantilever brakes
-- 3T Forge Ahead Stem (my favorite)
