PRO Wheels

When Shimano set out to build a wheel that matched the precision of Dura-Ace, they handed the project to PRO Wheels — the brand's performance component division — and the result is a focused range of carbon wheelsets engineered specifically for time trial and triathlon racing. The construction centers on TeXtreme® spread tow carbon fiber, an advanced layup process that delivers an unusually high stiffness-to-weight ratio by aligning fibers in wider, flatter tapes rather than traditional bundles. The 3-spoke front wheels provide the aerodynamic profile that matters most in solo efforts, while the disc-brake rear wheels run Dura-Ace 9000 hubs — matching the wheel's most mechanically loaded component to Shimano's flagship drivetrain spec. These wheels made their competitive debut at the Vuelta a España team time trial, which is a harder endorsement to argue with than any wind tunnel claim.

About PRO Wheels

PRO is Shimano's dedicated performance component brand, developing bars, stems, seatposts, saddles, and wheels alongside — and informed by — Shimano's drivetrain engineering. The wheels in this collection were co-developed with professional racing teams and made their competitive debut at the Vuelta a España team time trial, where the aerodynamic demands are as high as road cycling gets. TeXtreme® spread tow carbon is a construction method that uses wider, flatter fiber tapes to reduce resin content and increase structural efficiency — lighter and stiffer per gram than conventional carbon layups. Rear hubs are Dura-Ace 9000 spec, meaning the wheel's most mechanically loaded component is drawn from Shimano's flagship drivetrain line. Learn more at PRO's official website.

The five wheels on this page are a focused TT and triathlon lineup: 3-spoke front wheels in tubular and clincher options, and disc-brake rear wheels to match — a complete pairing system for riders who want matched PRO carbon front-to-back. Tubular and clincher versions are available across both disc and 3-spoke profiles.
