Cyclus Bottom Bracket Taps Bsa Thread

These Cyclus bottom bracket taps with BSA thread are expertly crafted for chasing and re-cutting English/BSA bottom bracket shells, ensuring that cups screw in smoothly and sit perfectly square within the frame. Supplied as a left and right tap pair, they allow you to clean up damaged or paint-filled 1.37" x 24 tpi threads, restoring accurate alignment on classic road, MTB, and city frames that adhere to the BSA standard, eliminating the need to replace the frame or depend on poorly cut threads. When used with a compatible Cyclus bottom bracket threading tool, the hardened steel dies create a clean, coaxial thread from both sides simultaneously, helping to minimize creaks, rough running, and premature wear in the bottom bracket. They’re a practical addition to your workshop, especially when your original taps are worn out or when you want to maintain a dedicated BSA set.
