I recently bought a used 1999 Trek 2000t. Drivetrain is completely shot on it. I got a great deal on a new HG chain and a Shimano CS-HG50 13-26t 8 speed cassette, which is same exact configuration as stock. Front chain rings need replaced on it also but its looking like it will just be cheaper to replace whole crankset. Bike currently runs 30/42/52t chainrings with 175mm square taper RSX cranks. The Shimano 2303 crankset has same exact configurations. My question is this... My current bottom bracket is 68x118, will that work with the 2303 crankset or should I replace BB with a shorter spindle? If so any recommendations on which model BB I should go with? Thanks for your input!!!
