Description
The CAMPAGNOLO PRO-TECH bottom bracket is specifically designed for the demanding conditions of off-road and gravel riding.
This bottom bracket features ProTech™ technology: a patented external seal that protects the ball bearings against the ingress of water, mud and sand, and a central waterproof ring in glass fibre-reinforced polyamide to prevent contamination from the inside.
The new cups mate with the oversized external stainless steel bearings mounted on the two Ultra-Torque™ half-axles firmly secured to the cranks. Thanks to the ProTech™ sealing system, performance is always optimal, whatever the conditions and terrain.
