I am new to cycling and am attempting to build up my first commuter bike from parts I already have. To start I am 6'5" and just purchased a 68 cm c-c (yeah, thats what I said) early 80's steel Fuji frame on e-bay. I am using a 9 speed SRAM cassette in the rear and the rear axle is 130mm. The spacing on the frame is also at 130mm. When I put the chain on the smallest sproket it rubs against the inside of the rear drop. I even tried a narrow chain which didn't help. Any ideas?
