As with the Dura Ace counterparts, the balanced relationship between three factors was at the forefront of the development: aerodynamics, stiffness and lower weight.\u003c\/p\u003e\n\u003cdiv\u003eThe Tubeless design of the WH-R8170 wheels not only ensures the appropriate propulsion and efficient power development, but also guarantees reliable performance in daily use. Compatibility with the proven 11-speed as well as the new 12-speed road cassettes is just as practical as comfortable.\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eC50 rim profile – Aerodynamic all-rounder\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eThe reduction of aerodynamic drag is the main discipline of the WH-R8170-C50 wheelset.

When developing the D2 rim profile, Shimano's engineers took both headwind and crosswind into account to ensure optimum performance under real-world riding conditions.\u003c\/p\u003e\n\u003cp\u003eExtensive prototype testing in the wind tunnel and on the road has shown that a wide rim shape and deep rim well offer the best performance under a wide range of conditions. At yaw angles from 0 to 15 degrees, the D2 rim design reduces drag better than other aerodynamic rims. It also increases the wheel's lateral stiffness and improves vertical directional stability, resulting in more control, comfort and durability on the road. \u003c\/p\u003e\n\u003ch4\u003e\u003c\/h4\u003e\n\u003ch3\u003eTechnical details of the WH-R9270-C50-TL wheelset\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003etyre type: clincher, folding tyre, Tubeless\u003c\/li\u003e\n\u003cli\u003ecross-section: symmetrical\u003c\/li\u003e\n\u003cli\u003eexternal width: 28 mm \/ internal width: 21 mm\u003c\/li\u003e\n\u003cli\u003eprofile height: 50 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003ebrake disc mount: Centerlock\u003c\/li\u003e\n\u003cli\u003efreewheel body: Shimano HG L \/ EV (11\/12-speed)\u003c\/li\u003e\n\u003cli\u003efreehub type: Pawl\u003c\/li\u003e\n\u003cli\u003ebearing: cup and cone (polished, CBN coated)\u003c\/li\u003e\n\u003cli\u003eseals: contact sealings\u003c\/li\u003e\n\u003cli\u003eO.L.D.: 12 x 100 mm \/ 12 x 142 mm (thru axle)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eaero spokes (Straightpull, double butted, bladed)\u003c\/li\u003e\n\u003cli\u003espoke count: 24 (front + rear)\u003c\/li\u003e\n\u003cli\u003efront spoke pattern: double crossed\u003c\/li\u003e\n\u003cli\u003erear spoke pattern: OPTBAL (left radial \/ right double crossed)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Shimano","offers":[{"title":"C-36L","offer_id":42668413845749,"sku":"","price":5900.0,"currency_code":"MYR","in_stock":true},{"title":"C-50L","offer_id":42668413878517,"sku":"","price":5900.0,"currency_code":"MYR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0858\/1100\/products\/shimano-ultegra-wh-r8170-c50-tl-wheelset-tubeless-1-wh-1056071.jpg?v=1650526129","url":"https:\/\/www.orbitcycle.cc\/products\/shimano-ultegra-wheelset-12sp","provider":"Orbit Cycle","version":"1.0","type":"link"}
