For precise and smooth operation around the crank arms, get Substance by BSD.
Substance is a central bottom bracket, complete with sealed precision bearings, CNC spacers, tubular spacers, a chainring bolt, and all other spacers needed for perfect alignment.
Notice:
Before purchasing a bottom bracket, it is necessary to check which type is compatible with your frame.
If it doesn't have integrated cups, an American bottom bracket will fit, but if your frame does have integrated cups, the bearings won't fit into the sleeves.This item has not been discussed yet. If you want to be first, click on the button Add post
