Campagnolo ProTech Bottom Bracket

The ProTech system features a patented external sealing ring that physically blocks water, mud, and grit from entering the bearing area. This is paired with a fiberglass-charged polyamide central tube, which provides a more durable, weather-resistant barrier than standard plastic or metal sleeves.

Campagnolo offers the ProTech bottom bracket in a wide range of standards, including BB30, BB386, BB86, BBRIGHT, English, Italian, PF30, and T47. You should verify your frame's specific bottom bracket shell standard and width before purchasing to ensure a proper fit.

No, this bottom bracket is specifically designed for the Campagnolo Ultra-Torque spindle interface. It is not compatible with cranksets from other manufacturers.

While it is optimized for the rigors of gravel riding and racing, it is an excellent upgrade for any road or cyclocross bike that frequently encounters wet, muddy, or dusty conditions. The enhanced sealing provides longevity benefits regardless of the specific discipline.

The ProTech system is designed to be low-maintenance, but like any bottom bracket, it should be inspected periodically. The external sealing ring is robust, but you should avoid using high-pressure water directly on the bearing area during bike washes to ensure the seals remain effective.
