2005 Co-Motion Supremo 145mm ~ 5000 miles
FSA MegaExo 54-42-30 (also have 48-38-26 usually used with the 13-29, probably going to modify this to an 11-29 since we spin out too easily with tailwind or slight downhill)
Campy Record 10 Sp Cassettes (11-23 and 13-29) originals (about 2500 miles on each)
Campy Record Ergo shifters
Campy Record Long Carriage Rear
Campy Record Triple Front
Campy Record Chain (got ~4000 miles out of last one)
We are both light riders - total weight of ~270 lbs (my wife never lets me see her weight but I don't mind as it's all muscle!) - so that probably accounts for the good longevity of parts.
Combination shifts great ( as good as my single) with only a couple of adjustments so far. I particularly like the ability to grab a handful of gears with one stroke of the shifters. I believe the new Shimano 10 sp. can do the same.
