BB SOCKET HOLLOWTECH II

A precise socket for external-cup bottom brackets that grips fully and torques cleanly. It’s a must for modern road and MTB builds. Now available for Indian riders via Cobbled Climbs.

Hailing from Taiwan, Birzman elevates cycling tools and accessories into objects of utility and design. Every pump, multi-tool, and bag reflects meticulous attention to function and form. For Indian cyclists, Birzman is the mark of self-sufficiency—gear that turns roadside repairs and fine-tuning into a ritual of craft.
