Product Overview
WorldTour‑proven performance. Steel bearing durability. The same precision engineering that powers Tadej Pogačar – now with the reliability of chromium steel.
Bikone is the Spanish bottom bracket specialist trusted by UAE Team Emirates-XRG – the team of four‑time Tour de France winner Tadej Pogačar.

Every unit is CNC‑machined from aerospace‑grade aluminium, hand‑assembled, and backed by an industry‑leading warranty.
