Our 4X and 3X tools are engineered to the same high standards as the bottom brackets they install. Each is precision machined to fit its respective bottom bracket flange exactly, with a deep overlap and no play. This makes installation straightforward and allows you to apply the correct torque with confidence that the tool won’t slip, unlike the many thin and unstable spanners on the market.
The tools require a ½” driver.
This Tool-set is for installing Module 2 and Module 47 bottom brackets.
