Hah, great thread!
This one started out its life as a Hybrid Diamondback but really yearned to be something a bit more adventurous so it became a big-tire on-and-off-road bike. Campy 10-speed brifters, Shimano 8-speed cassette and rear derailleur, Race Face crankset, Bruce gordon 700c x 43mm Rock 'n' Road tires, Brooks B-17 saddle and Silca frame pump.
This Motobecane LeChampion went through a few identities. First with TA Cyclotouriste cranks, and Campy Rally derailleur and Campy downtube shifters.
Next it adopted the briftered Shimergo Campy 10-speed x Shimano 8-speed identity.
Finally it went lean and mean and became my fixed gear trainer with Dura Ace track hubs, stripped down TA crankset, and Mafac Racer Brakes... and a Silca frame pump.
