Promax SC-1 Square Tapered Euro Bottom Bracket

J&R Helpful Hint - The spindle length depends mostly on the brand/style of crank arm.  For example; Odyssey Black Widow cranks need the 118mm-122mm length; Answer, Speedline, AC cranks and SINZ cranks require the 113mm-115mm length.  There are some cranks/frame combinations where a 108mm will work.  Check to see what your bike came with or consult our sales staff.
