Tripeak AOPW Oversized Ceramic Pulley Wheels for Shimano Ultegra R8100/R8150 & 105 R7100/R7150 (UK Stock)

Upgrade your drivetrain with the Tripeak AOPW Oversized Ceramic Pulley Wheels, purpose-built for Shimano Ultegra R8100 / R8150 and Shimano 105 R7100 / R7150 12-speed groupsets. Designed for cyclists who demand maximum efficiency, these oversized jockey wheels offer a noticeable performance advantage for both racing and endurance riding.

 

Featuring a patented asymmetric cage design, this system allows a larger 18-tooth lower pulley while retaining compatibility with the original Shimano derailleur cage. Combined with premium NC Race G3 ceramic bearings, the result is reduced friction, smoother shifting, and greater drivetrain longevity even in wet British weather or alpine conditions across Europe.

 

Whether you’re competing in a UK time trial, tackling a Gran Fondo, or shaving watts on your weekend ride, these ceramic oversized pulley wheels are the upgrade of choice for marginal gains.

 

Key Features:

✅ Designed for Shimano Ultegra R8100 / R8150 and 105 R7100 / R7150 12-speed systems

✅ 12T upper and 18T lower oversized pulley wheel configuration for reduced chain tension

✅ Ultra-efficient ceramic bearings with G3-grade ceramic balls for minimal rolling resistance

✅ CNC-machined 6061 alloy cage and PA+GF composite pulley wheels for lightweight durability

✅ Narrow-wide tooth design enhances chain stability and shifting accuracy

✅ Direct-fit installation with no chain length modification required in most setups

✅ Available in multiple anodised colours to suit your bike’s aesthetic

✅ Backed by a 4-year manufacturer’s warranty

✅ Suitable for road cyclists, triathletes, and time trial specialists across the UK & EU

 

Commonly referred to as ceramic jockey wheels, ceramic oversized jockey wheels, or simply oversized pulley wheels, this upgrade is a proven choice for riders seeking efficiency, performance, and a competitive edge.
