Designed for tubeless use, you benefit from improved riding control and significantly more grip on every kilometer when racing against the clock thanks to the lower air pressure. The susceptibility to punctures is also reduced.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003cspan\u003eThe hubs are also a proprietary Vision development. Their body is forged from high-quality aluminum, resulting in high rigidity. The perfectly sealed industrial ball bearings guarantee smooth running and are absolutely maintenance-free. A toothed disk freewheel with conically arranged disks ensures uninhibited propulsion. This has 72 interlocking points and reduces the free travel to an incredible 5°. In addition, spiral-milled guide grooves on the freewheel body, on which the two toothed pulleys sit, ensure perfect functioning.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eTechnical data:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eArea of application: Road bike, time trial, triathlon (time trail)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eWheel size: 28\" (ETRTO: 622x21 mm)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRim type: clincher and folding tires\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBrake type: Disc brake\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eBrake disc mount: Center Lock\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eHub material: Aluminum\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRim material: Carbon\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eFairing material: Carbon\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eInner width: 21 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eOuter width: 31.1 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRim height: Disc wheel\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eSpokes: Steel with closed carbon fairing\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRear axle standard: 12x142 mm thru axle\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eRear bearing: 4x sealed industrial ball bearings\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eFreehub compatibility: \u003cmeta charset=\"utf-8\"\u003e Shimano Road 11\/12 , \u003cmeta charset=\"utf-8\"\u003e12-13 Speed SRAM XDR\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eFreewheel type: toothed pulley freewheel, 2 toothed pulleys, 72 ratchets\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003erecommended tire width: 25 - 32 mm\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003emax. air pressure: n\/a\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003etubeless capable: yes\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003emaximum system weight: n\/a\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003evalve hole: Presta valve (SV)\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eColor rim \/ finish: black \/ UD Carbon matt\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eColor decor: glossy black, white\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eColor hubs: black\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Vision","offers":[{"title":"Shimano Road 11\/12 Speed","offer_id":48546238300372,"sku":"042155-01-700","price":2650.0,"currency_code":"CAD","in_stock":true},{"title":"SRAM XDR 12\/13 Speed","offer_id":48546238333140,"sku":"042155-02-700","price":2650.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/4092\/6149\/files\/Screenshot2026-08-26at8.59.31AM.png?v=1787749369","url":"https:\/\/www.brownssports.ca\/products\/metron-ttw-rear-wheel","provider":"Brown's Sports \u0026 Cycle Co.
