Easy install, rides quiet and smooth like you'd want. Sizing is accurate. Review: Good fit. Good price! - Got the bottom bracket for my fixie. Worked perfect. The bearings and everything looked clearly brand new. Feels good to spin. Went into the frame with no issue. My original crank arms went on and accepted the included spindle bolts just fine! The bike shop wanted to charge $30 labor and $60 for the BB! This saved me ALOT of money! I have yet to put any real miles on the BB and if anything goes wrong I will adjust my review, but so far I don't believe I'll have any problems! ## Features - 【Broad Compatibility】Compatible with BSA bicycle base threads of 68/80/90/100/110/120 mm.
