The Revolution BSA30 BB provides the ultimate in threaded bottom bracket performance. Fitting a 30mm spindle in a BSA frame demands the peak in machining accuracy and precision, and we have delivered a BB shell that is both light, yet impeccably aligned. A specially-narrowed neck helps to provide clearance for internal frame fittings and cables, improving the compatibility with more frames. We use top-grade NTN 6806 LLB precision steel bearings for durability, reliability, and smoothness. Each bearing can be removed and replaced using standard bearing tools, allowing the bottom bracket to be used for a long lifetime.
