I need to replace the sq taper cartridge BB (9spd Deore triple crank) on my Raleigh C500 hybrid rain commuter.
The original cheesy Chinhaur is 68mm X 111mm English. I plan on replacing it with a Shimano UN54.
The shimano comes in 110 and 113mm lengths. Would the recommendation be to go 1mm shorter or 2mm longer? The granny ring is almost never used. It "appears" that either will not interfere with the frame etc. I'm also assuming I'd need to adjust the FD (lx) stops after too.
