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.\u003c\/p\u003e\u003c\/div\u003e","products":[{"product_id":"pro-3-spoke-clincher-front-wheel","title":"PRO 3-Spoke Clincher Front Wheel","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003ePRO 3-Spoke Clincher Front Wheel\u003c\/strong\u003e is built for riders who want the stiffness and speed of a tri-spoke design on their time trial or triathlon bike without the crosswind handling penalty of a full disc wheel. Tri-spoke wheels sit in a useful middle ground: they're stiffer and faster than a standard spoked wheel, but the open sections between the three blades let wind pass through in a way a solid disc can't, which makes the front end easier to control on exposed, gusty courses. Choosing the clincher version over a tubular also matters on race day, since a clincher lets you fix a flat with a spare tube rather than needing a fresh glued tire.\u003c\/p\u003e\n\u003cp\u003ePRO builds this wheel the same way it builds its disc wheels: a 3K carbon 2x2 twill weave forms the exterior walls over a foam core interior, wrapped around a wide aluminum rim. That aluminum rim carries a machined brake track, which matters because this is a rim-brake wheel, not a disc-brake one, and a machined track is what gives you consistent, reliable braking in wet or variable weather rather than the fade you can get from an all-carbon braking surface. The rim is wide enough that PRO recommends a minimum 24mm tire, keeping the tire-to-rim transition smooth at speed.\u003c\/p\u003e\n\u003cp\u003eAt the center of the wheel is a Shimano Ultegra 6800 hub, giving it smooth, dependable bearing performance without stepping up to a Dura-Ace-level price. The rim itself is 65mm deep, deep enough to deliver a real aerodynamic benefit on flat and rolling time trial or triathlon courses, though it's not the wheel you'd choose for a hilly event where lighter, shallower wheels climb better. Total weight comes in at 1,040 grams for the front wheel. Because the rim is so deep, you'll need an 80mm valve, either built into your tube or added with a valve extender, to reach the valve hole through the full rim depth. The wide rim surface also has enough flat area to mount a speedometer magnet with dual-sided tape if your setup calls for one.\u003c\/p\u003e\n\u003cp\u003ePRO originally brought this tri-spoke design to market as a tubular wheel before releasing it as a clincher, so the aerodynamic shape and stiffness carry over from a wheel that had already been raced and refined. As the in-house component brand under Shimano, PRO builds this wheel to pair naturally with a Shimano-equipped time trial or triathlon bike, though the Ultegra hub works with any compatible cassette body regardless of what groupset drives the rest of the bike. It ships with a PRO wheelbag and an Ultegra skewer included, so it's ready to travel to a race and go straight onto the bike. For a rider who wants a purpose-built front tri-spoke for flat-to-rolling timed events, without committing to the maintenance demands of a tubular tire, this is a direct, well-supported option.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Default Title","offer_id":43705702842412,"sku":"PRWH0040","price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-3-spoke-clincher-front-wheel-7237424.jpg?v=1771299139"},{"product_id":"pro-clincher-disc-wheel","title":"PRO Clincher Disc Wheel","description":"\u003cdiv\u003e\n\u003cp\u003eThe \u003cstrong\u003ePRO Clincher Disc Wheel\u003c\/strong\u003e solves a problem that only shows up when things go wrong mid-race: a flat tire on a tubular wheel means glue, patience, and time you don't have in a triathlon. Because this is a clincher, a flat is a tube swap, not a project. That single detail is the reason PRO built a disc wheel around clincher compatibility instead of the tubular construction more common in this category.\u003c\/p\u003e\n\u003cp\u003eThe disc itself is a sandwich construction — carbon-fiber twill on both faces with a Rohacel structural foam core in between. The foam gives the wheel some give over rough pavement, while the carbon skins keep it rigid enough to drive power efficiently. PRO based this design on their Tubular Disc, which in turn traces back to their pro-level Textreme Disc, so the layup approach has already been proven at a higher price point before showing up here in clincher form. The rim itself is an aluminum alloy hoop with a machined braking surface, which matters for all-weather stopping power — carbon braking surfaces can fade in the wet, and an alloy track doesn't have that problem.\u003c\/p\u003e\n\u003cp\u003eInside the hub is a Shimano Ultegra 6800 cassette body and rear hub, which puts this wheel on common ground with most drivetrains on the road: it's compatible with Shimano and SRAM 10\/11-speed cassettes, so swapping it onto race day doesn't mean hunting for a specific freehub. The complete wheel weighs 1,590g. It's not the lightest disc on the market, but weight isn't really the point of a rear disc — aerodynamics on a flat or rolling time trial course is, and the enclosed disc shape is what's doing the work there, not the wheel's mass.\u003c\/p\u003e\n\u003cp\u003eA few things to know before mounting it: the rim is wide enough that PRO recommends a minimum tire width of 24mm — narrower tires won't sit right on the profile. You'll also need a disc-specific adapter to inflate it with a floor pump, since a standard head won't reach through the enclosed disc; a pipe-style adapter works. The wheel ships with a wheelbag and a valve extender sized for 48-60mm valve stems, which covers most aero tubes. \u003c!-- VERIFY: RA Cycles page has conflicting notes — one section says the rider must supply their own quick release and valve hole cover, another says the wheel includes an Ultegra skewer.

PRO is Shimano's in-house component brand, building wheels, bars, posts, and saddles alongside Shimano's drivetrains, and this wheel carries that pro-team pedigree directly: it debuted at the opening team time trial of the Vuelta a España, built through what PRO calls a \"Co Creation\" process with the riders who'd actually race on it. A three-spoke front wheel occupies a specific niche in the wheel world. It holds a line in a straight headwind, stays composed in a crosswind, and does both while staying laterally stiff under hard efforts out of the saddle, which is why the format has stayed popular in time trial and triathlon racing even as full disc wheels have taken over on the rear.\u003c\/p\u003e\n\u003cp\u003eThe wheel is built primarily from TeXtreme carbon fiber cloth, a material that uses spread-tow fabric in place of the woven yarns found in more conventional carbon layups. PRO chose it because spread-tow construction is engineered to deliver a stiffer, lighter structure than standard weave, and it leaves behind a distinctive checkerboard pattern on the rim and spokes rather than the uniform matte or gloss finish most carbon wheels share. It's a look that doubles as a material signature: you can tell at a glance this wheel is built differently from a standard three-spoke design. PRO paired the look intentionally with its TeXtreme rear disc wheel, so a rider running both gets a matched aero front-and-rear setup rather than two wheels that merely happen to be black.\u003c\/p\u003e\n\u003cp\u003eAt the center of the wheel sits a Shimano Dura-Ace 9000 front hub, a hub PRO leaned on for its smooth roll and long-term durability rather than reinventing the hub internals to match the aero rim. The three spokes themselves are directional, marked as such on the wheel so they get installed the correct way, and shaped to keep airflow attached across a range of yaw angles rather than just straight into the wind. The rim runs a 65mm depth, a mid-depth profile rather than an ultra-deep TT-only shape, at 24mm of width, and the complete wheel weighs 765 grams. That combination sits in a middle ground between all-out aero depth and a weight a rider can still turn over on rolling terrain, rather than a wheel that's only fast in a dead-flat time trial and dead weight anywhere else. It's a rim brake wheel, with the carbon rim itself doing double duty as the braking surface rather than routing to a disc rotor.\u003c\/p\u003e\n\u003cp\u003eRunning this wheel day to day comes with a few practical notes worth knowing before buying. The braking surface is carbon, so it needs carbon-specific brake pads rather than standard pads made for aluminum rims, and they'll stop differently than an alloy rim does, especially in the wet. Because it's a tubular, tires need to be glued or taped on rather than simply inflated, and PRO recommends nothing narrower than a 24mm tire to keep a clean transition between tire and rim. The valve is also recessed enough that a valve extender of at least 65mm is required to reach a floor pump or CO2 head. On the plus side, the wheel ships with its own quick release skewer and a wheel bag, and if a rider wants a speedometer magnet, a sticker-style magnet is the practical choice since the directional spoke design doesn't leave an obvious spot for a traditional spoke-mounted magnet.\u003c\/p\u003e\n\u003cp\u003eThis is a wheel built for a specific kind of riding: time trials, the bike leg of a triathlon, and flat-to-rolling road races where holding an aero position and minimizing drag matters more than climbing weight. It's not the wheel to reach for on a mountainous group ride or a gravel day, but on a flat 40k time trial course or a triathlon bike leg, that's exactly the terrain this shape was developed to handle. It's sold here as a single front wheel rather than a set, in black, and it's marked as final sale. For a rider who already knows they want a three-spoke front paired with a disc rear, or who's specifically chasing the wind-tunnel-informed shape that came out of a real WorldTour development process, this is a wheel with a legitimate racing pedigree behind it, at a meaningful discount off its original price, rather than just a name borrowed from one.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"PRO","offers":[{"title":"Black","offer_id":43516866428972,"sku":"PRWH0038","price":1499.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/7684\/9196\/files\/pro-textreme-carbon-3-spoke-tubular-front-wheel-1582342.jpg?v=1771299022"},{"product_id":"pro-textreme-carbon-tubular-disc-wheel","title":"PRO TEXTREME Carbon Tubular Disc Wheel","description":"\u003cdiv\u003e\n  \u003cp\u003eThe \u003cstrong\u003ePRO Textreme Carbon Tubular Disc Wheel\u003c\/strong\u003e is a purpose-built time trial and triathlon rear disc wheel from PRO — Shimano's component brand, whose products have been raced at the professional level by Shimano-sponsored teams including Team Sky. This is a single rear wheel designed for tubular tires and rim brakes, built around a Shimano Dura-Ace FH-9000 rear hub and shaped into a mixed flat\/lenticular profile that maximizes aerodynamic efficiency while maintaining rear derailleur clearance. At 1,050g, it sits at a competitive weight for a carbon disc wheel used in professional triathlon and time trial competition.\u003c\/p\u003e\n\n  \u003cp\u003eThe rim is constructed from Textreme, a spread-tow carbon fiber material developed by Oxeon. Where conventional carbon fiber uses woven or braided cloth, spread-tow construction spreads ultra-thin carbon fiber tapes into wide, flat plies before layup. The result is a higher fiber-to-resin ratio, reduced fiber crimp, and a stiffer structure per gram — because straight fibers carry load more efficiently than fibers that change direction through a weave pattern. The monocoque construction shapes the entire disc into a single integrated carbon structure rather than assembling it from separate bonded sections. Textreme is identifiable by its distinctive checkerboard appearance, a direct visual result of the spread-tow method.\u003c\/p\u003e\n\n  \u003ch3\u003eMixed Flat and Lenticular Disc Profile\u003c\/h3\u003e\n\n  \u003cp\u003eThe disc shape on the Textreme uses a mixed flat and lenticular profile — a standard engineering solution for rear disc wheels used with a rear derailleur. The drive side is flat, giving the derailleur clearance at the largest cog on the cassette. The non-drive side is lenticular, the convex profile that reduces aerodynamic drag and generates lift as the wheel spins. The disc gets progressively wider from the rim bed outward: 39mm at 79mm from the rim bed, 46mm at 158mm, and 51mm at the widest point at 237mm from the rim bed. That progressive taper is characteristic of a properly engineered lenticular profile. The 24mm rim bed width puts the tire at the correct width to smooth the aerodynamic transition from tire to wheel — Shimano recommends tubular tires of 24mm or wider for this reason.\u003c\/p\u003e\n\n  \u003ch3\u003eDura-Ace FH-9000 Hub and Compatibility\u003c\/h3\u003e\n\n  \u003cp\u003eThe hub is Shimano's Dura-Ace FH-9000 rear hub, the top-tier production rear hub from Shimano's flagship groupset family. The FH-9000 delivers smooth, consistent bearing performance and a freehub body that accepts standard Shimano HG cassettes for 10- and 11-speed drivetrains, compatible with SRAM cassettes sharing the same spline pattern. The axle is 130mm quick release — the standard spacing for road and TT frames. This is a rim brake wheel for quick release dropouts. It is not compatible with thru-axle frames or disc brake calipers.\u003c\/p\u003e\n\n  \u003cp\u003eBefore purchasing, verify rear triangle clearance on your frame. The lenticular non-drive side profile is significantly wider than a standard rim, and it may not fit all chainstay and seatstay configurations. Shimano recommends measuring the left side of the rear triangle to confirm fitment. The wheel ships with a quick release skewer, valve extender, wheel bag, and a sticker to cover the valve hole. Shimano specifies carbon-specific brake pads for use with this wheel.
