Bottom Brackets
Bottom brackets are the understated workhorses of the bicycle drivetrain. We rely on them to spin smoothly, but the bearings are often heavily exposed to unfavorable elements due to their location at the bottom of the bike. Therefore, it is important to choose a quality bottom bracket with quality seals. There are many varieties of bottom brackets from threaded square taper units to press-fit bearing cups.
