Where a spoked aero wheel still has to manage airflow around dozens of individual spokes, a disc wheel presents one continuous carbon surface to the air, which is why disc wheels are a fixture at the rear of TT and triathlon bikes but are never used up front, where a spinning disc would catch crosswinds dangerously.\u003c\/p\u003e\n\u003cp\u003eThe rim section is a full-carbon, 45mm-deep clincher profile with a 21mm internal rim width, built around Vision's V-1000 PRS (Power Ratchet System) hub with sealed chromoly bearings and a centerlock disc-brake mount. It's set up for a 12x142mm thru-axle rear end and is tubeless-ready on top of standard clincher tyre compatibility, so it can run a tubeless tyre and sealant setup for lower rolling resistance without a separate tube.\u003c\/p\u003e\n\u003cp\u003eIn practice this wheel earns its keep specifically on individual time-trial stages, triathlon bike legs and similar flat-to-rolling courses without heavy crosswind exposure — conditions that are common on the long, straight highway TT and triathlon bike courses found across India. It is not a wheel for criterium racing, group rides or anywhere handling in gusty wind matters more than outright aero efficiency.\u003c\/p\u003e\n\n\u003ch5\u003eWhy You'll Like It\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eDisc-wheel aero gain where it counts\u003c\/strong\u003e\u003cbr\u003eA solid rear disc removes rear-wheel turbulence almost entirely on the kind of straight, fast courses time trials and triathlon bike legs are run on.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTubeless-ready without giving up tyre choice\u003c\/strong\u003e\u003cbr\u003eYou can run it tubeless for lower rolling resistance, or stick with a standard clincher tube setup — the rim supports both.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModern disc-brake compatible\u003c\/strong\u003e\u003cbr\u003eThe centerlock mount and 12x142mm thru-axle spec means it drops straight onto a current-generation disc-brake TT or triathlon frame without an adapter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSmooth, low-maintenance hub\u003c\/strong\u003e\u003cbr\u003eThe V-1000 Power Ratchet System hub with sealed chromoly bearings is built for consistent engagement and low service needs through a race season.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNo spokes to true or break\u003c\/strong\u003e\u003cbr\u003eAs a solid disc, there's no spoke tension to maintain and no individual spoke that can fail mid-race the way a conventional wheel's can.\u003c\/p\u003e\n\n\u003ch5\u003eWho Is It For?\u003c\/h5\u003e\n\u003cp\u003eThis wheel is for time-trial specialists and triathletes who have a dedicated TT or tri bike with disc-brake, thru-axle compatibility and who race on flat-to-rolling courses without serious crosswind exposure — exactly the profile of most closed-road time-trial courses and triathlon bike legs run in India. It is a rear-only wheel, so it's bought to pair with a separate front wheel (typically a deep-section spoked or three\/four-spoke wheel) rather than as a complete wheelset.\u003c\/p\u003e\n\u003cp\u003eIt is not the right choice for a rider whose \"TT bike\" doubles as a general road or training bike, or for anyone racing courses with significant open crosswind sections, where a solid disc becomes harder to control than a spoked aero wheel.\u003c\/p\u003e\n\n\u003ch5\u003eGood to Know\u003c\/h5\u003e\n\u003cp\u003eHave your local shop confirm your frame's disc-brake rotor size and thru-axle length match before fitting, since centerlock and 12x142mm thru-axle are now common but not universal across TT and triathlon frames. Run tyre pressure appropriate to your weight and the rim's 21mm internal width — a slightly wider tyre than you'd run on a narrower rim tends to measure out closer to its stated width and ride more comfortably at the same pressure.\u003c\/p\u003e\n\u003cp\u003eIf running tubeless, use a sealant designed for high-pressure road\/TT tubeless setups and check sealant levels periodically, the same as you would with any tubeless-ready aero wheel, to keep the system sealing properly between races.\u003c\/p\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Position:\u003c\/strong\u003e Rear (disc wheel; sold individually, not as a front\/rear pair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Use:\u003c\/strong\u003e Time trial \/ triathlon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim Depth:\u003c\/strong\u003e 45mm (full carbon disc profile)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Rim Width:\u003c\/strong\u003e 21mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Rim Width:\u003c\/strong\u003e 31mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Size:\u003c\/strong\u003e 700c (ISO 622)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1008g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRear Axle Type:\u003c\/strong\u003e 12x142mm thru-axle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake Type:\u003c\/strong\u003e Disc brake, centerlock mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTire Type:\u003c\/strong\u003e Clincher, tubeless-ready\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub:\u003c\/strong\u003e Vision V-1000 PRS (Power Ratchet System), sealed chromoly bearings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpoke Count:\u003c\/strong\u003e Not applicable — solid carbon disc wheel (no spokes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRim Material:\u003c\/strong\u003e Carbon (unidirectional carbon rim and disc fairings)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eAdditional Information\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImported By:\u003c\/strong\u003e We Snap India, M.
