If your Campagnolo Ultra-Torque setup is due for fresh bearings and you want a performance-focused replacement, this is the right style of upgrade. The 25 x 37 x 6 mm format matches the Ultra-Torque application, and the hybrid ceramic build is aimed at riders chasing smooth rolling and low friction rather than maximum weatherproofing above all else.

The Black Bearing 6805W6 is a ceramic hybrid replacement bearing built around the 25 x 37 x 6 mm size used for Campagnolo Ultra-Torque bottom bracket applications. For the right bike, it gives you a clean way to refresh a worn setup or move from a standard steel bearing to a lower-friction, performance-focused option without replacing the entire system.
What matters here is the balance of speed and protection. You’re getting Si3N4 silicon nitride balls, steel or stainless-steel rings depending on reference, a low-friction polyamide cage, and 2RS low-friction seals to help keep out water and dust. That makes this bearing a smart pick for riders who want a fast-spinning feel for road racing, hard training, fast gravel or cyclocross, while still keeping sensible sealing for real-world use.
The key buying point is compatibility: this bearing is for Campagnolo Ultra-Torque cranksets using the 25 mm spindle / 25 x 37 x 6 mm bearing format. Ceramic bearings can deliver smoother running and lower resistance, but the gains are typically most meaningful for riders who keep their bikes well maintained and want every small efficiency advantage. If you ride through constant wet weather and prefer the longest service intervals with the least fuss, a premium steel or stainless option can still be the more practical choice.
Ideal for the rider rebuilding a Campagnolo Ultra-Torque bottom bracket who wants a direct-fit ceramic upgrade for racing, fast training or a premium performance refresh.
Campagnolo Ultra-Torque fit
Designed around the 25 x 37 x 6 mm format used for Campagnolo Ultra-Torque bottom bracket applications, so it suits the intended crank system rather than being a generic bearing guess.
Hybrid ceramic construction
Uses Si3N4 silicon nitride balls with metal races for the classic ceramic-hybrid mix of smooth running, low drag and performance-focused feel.
Low-friction seal design
The 2RS low-friction seals aim to keep contamination out without adding unnecessary drag, giving a sensible balance for fast bikes used in the real world.
Cycling-specific build
Built specifically for cycling use, with materials and grease chosen for bearing-driven parts such as bottom brackets, wheels and pedals.
Polyamide cage
The low-friction polyamide cage supports smooth rotation under load and suits a bearing designed around efficiency.
Direct replacement approach
Made as a 100% compatible replacement for the original bearing position, which is exactly what you want when servicing an existing Ultra-Torque setup.
Performance / competition focus
This is the right choice when your priority is speed, efficiency and premium feel rather than the cheapest replacement bearing.
