I decided to clean and lube my bottom bracket on a 1987 trek 330
The crank and bottom bracket is (SR) Sakae Ringyo.
The measurements have me curious
The spindle overall measures 117mm the left side measures 32mm and the right side measures 33.5mm
most spindles that I see that are offset usually measure at least 5mm longer on the right side.
Would a company actually go to the trouble of making an offset spindle for 1.5mm? Or could it be possible that their tolerances are off that much?
