Tange Bottom Bracket, Square Taper, JIS

Great value

Don't be afraid of the low price, the bearing is super smooth, much smoother than a 90 dollar GXP bearing I have. It has Boron Steel cups and axle which is 100 grams heavier than CroMoly but super strong anyway. Great Bottom bracket that reminds me of the Shimano UN72 from way back. It's perfectly silky smooth like an old Shimano BB before they changed the quality, but just boron steel axle instead of CroMoly.

Works great and easy to install
