Race Face Cinch Bottom Bracket is the threaded bottom bracket for a specific BSA frame standard and Race Face Cinch cranks. It is the sensible replacement when the original unit has developed play, noise or roughness through the pedals.

The external seal is the key detail here. It adds protection around the bearing area, which matters on wet rides, muddy Trail laps and bikes that regularly see frequent washing. It is a straightforward choice for riders who want the correct Race Face fitment rather than adapting mismatched parts.

Key characteristics

• BSA threaded fitment – suits frames made for this particular threaded bottom bracket arrangement.
• Race Face Cinch crank compatibility – keeps the crank and bottom bracket interface matched as intended.
• External seal – helps limit the entry of water and trail grit around the bearing area.
• Threaded cups – allow conventional installation and removal with the appropriate bottom-bracket tool.
• Race Face replacement part – a practical option when renewing a worn Cinch bottom bracket.
• Model-specific application – checking the frame threading and crank compatibility before purchase avoids an incorrect fit.

On the trail

A bottom bracket should disappear into the background, and this Race Face unit does exactly that when fitted correctly. The external sealing is particularly worthwhile for riders who regularly encounter puddles, mud and wash-downs, where contamination can shorten bearing life. A fresh unit also helps restore the solid, quiet feel at the pedals when the old bottom bracket has begun to creak or run roughly.

Recommendation

Choose the Race Face Cinch Bottom Bracket if your bike uses the matching BSA threaded frame standard and a compatible Race Face Cinch crankset. It suits Trail, Enduro and Downhill riders who value a correct, well-sealed replacement for regular all-weather riding.
