For riders who've invested in Shimano Dura-Ace, every component choice matters. The Tripeak AOPW Oversized Ceramic Pulley Wheels for Dura-Ace R9250 and R9200 are the logical next step after speccing the finest groupset Shimano produces — a precision upgrade that extracts more from what you've already built.

At the heart of this system is the patented asymmetric cage design, which accommodates a larger 18-tooth lower pulley without any modification to your stock Dura-Ace derailleur. The result is a shallower, smoother chain arc that measurably reduces drivetrain friction. Combined with Grade 3 NC Race ceramic bearings — the highest specification Tripeak offers — independent testing shows savings of 3 to 5 watts at race pace. On a 4-hour ride, that difference is felt.

Trusted by WorldTour professionals at Astana XDS and Kern Pharma, these pulleys are engineered to perform under the same conditions you'll face: wet British climbs, alpine sportives, or flat-out criteriums. The narrow-wide tooth profile keeps your chain locked in line regardless of conditions, while the composite body resists flex and wear over thousands of kilometres.

Available in black, silver, gold, and red to complement your Dura-Ace finish. Backed by a 4-year warranty and includes ceramic grease for bearing maintenance. In stock and shipped from the UK by Eminence Cycle Co., official UK distributor for Tripeak.
