I'm a newbie to the forum and want to get an opinion about a slight bottom bracket length mismatch.
My learning project bike is an '01 Diamondback MTB (curbside find treasure). The bottom bracket was dry and noisy so I pulled it. Its a square taper measuring 16.4 mm. The choices for replacement were 15.5 and 17.5 mm. I opted for the 17.5 which actually measures 17.8 mm. The entire 1.4 mm difference is on the drive side.
My question is whether that 1.4 mm is likely to give problems adjusting the FD and with shifting?
Thanks in advance and for the other great information presented here in the mechanics forum.
