Sealed cartridge bearings in a bottom bracket sit directly in your pedaling force path, which means friction here costs you watts with every crank rotation. This stainless steel bearing kit replaces worn bearings in Campagnolo Ultra-Torque cranksets, restoring the smooth rotation that deteriorates as seals wear and contamination works past the bearing shields. When you start feeling resistance or hearing grinding from the bottom bracket area, fresh bearings bring back the efficiency you had when the crankset was new.

The kit includes two bearings and two seals—everything needed for a complete bearing service on one crankset. Each bearing measures twenty-five millimeters inner diameter, thirty-seven millimeters outer diameter, and six millimeters thick, which matches the 6805N-2RS bearing designation used across the Ultra-Torque system. The stainless steel races resist corrosion if moisture penetrates the seals during wet riding, and the sealed cartridge design keeps contaminants away from the bearing surfaces longer than serviceable cup-and-cone designs.

This bearing kit was standard equipment on two thousand nine and later Chorus cranksets and pre-two thousand eleven Record Ultra-Torque cranksets, but it fits all Campagnolo Ultra-Torque cranks regardless of groupset level—Record, Chorus, Centaur, and Veloce. The bearing dimensions remain consistent across the Ultra-Torque lineup, so you use the same replacement kit whether you're servicing an entry-level or flagship crankset. The kit also works with Fulcrum Ultra-Torque cranksets, which share the same bearing interface.... Read More
