Still running Shimano's trusted 11-speed platform? The Tripeak AOPW Oversized Ceramic Pulley Wheels for Shimano 105 R7000 and Ultegra R8050 prove that upgrading to Di2 isn't the only way to find more speed. This direct-fit system gives your existing groupset a new lease of life — improved efficiency, smoother shifting, and the confidence of race-proven engineering, without the cost of a full drivetrain replacement.
Many riders on 11-speed Shimano systems assume their groupset has reached its ceiling. It hasn't. The weakest link in any mechanical drivetrain is the standard pulley wheels — small, steel-bearing components that generate unnecessary friction with every pedal stroke. Swapping to the Tripeak AOPW immediately addresses this. The enlarged 18-tooth lower pulley, ceramic bearings, and asymmetric cage design collectively recover 3–5 watts that your drivetrain is currently losing to friction.
For audax riders, long-distance tourers, and club racers who aren't ready to abandon a perfectly functioning 11-speed setup, this is one of the best pound-for-pound performance upgrades available. Durable enough for year-round British riding, precise enough for racing season. Includes ceramic grease, 4-year warranty, and ships from UK stock.
