Brand new in box ultra high performance. These are RIM BRAKE wheels and are not compatible with disc brake bikes unless you want to rebuild the rims onto disc brake hubs. Lovely mid depth (same as Bora 35′s) carbon rim wheels, the accepted best depth now for climbing/all round road use. Not as fast as deeper 55mm rims for example, but lighter. And better in cross winds. Especially for lighter riders. Who can get blown off course with deeper rims. These wheels are much like the excellent Spin on These Fatboys/Revolutions, with a. Very high quality carbon fibre. Construction with similar identical? U-shape toroidal profile and of course th. Width. The rims themselves may well even be the same. The fantastic 21mm internal width gives much more air volume and improves comfort massively over narrower rims. Also much more aero (especially with 25/28/30c tyres) and better puncture resistance with less rolling resistance. These are precision handbuilt with genuine Sapim CX Ray spokes (the best) and black brass nipples for best strength, reliability and long life. Also includes 3 x spare Sapim CX Ray spokes (one of each for front, and both sides rear), a full set of 4 carbon compound brake pads, a very high quality. Skewers set (look to be the same as the excellent Miche XR ones) and tubeless valves (tubeless tape is factory fitted). Ready for mounting hooked tubeless tyres or clinchers with inner tubes. So a significant saving especially considering the wheels are 100% brand new in box. The Selcof 35 Carbon Rim Wheelset is lightweight, strong, and aerodynamic. A brilliantly versatile upgrade to any road bike. Designed and built to excel from the toughest fast rolling sectors to the highest mountains. Tubeless ready and clincher compatible carbon rims / 35mm Deep / 28mm External Width / 21mm Internal Width. Japanese made Toray T700/T800 carbon fibre rim. Unidirectional sidewalls with 3K weave spoke bed. High heat resistant compound brake track. High performance forged and CNC machined QR hubs. Fast engagement 6 pawl freehub and 36t ratchet. Premium Sapim CX-Ray Aero bladed straight pull spokes with UK weatherproof brass nipples. Perhaps the most important upgrade you can make to any road bike. 35mm rim depth offers perfect versatility. Low weight allows for effortless climbing performance, yet they remain fast and efficient on rolling terrain. The rims are constructed using only premium Japanese made Toray T700/T800 carbon fibre. Unidirectional sidewalls, 3K weave rim bed and spoke eyelets result in an extremely strong, vibration dampening, yet actively responsive wheel. High heat resistant compound brake track disperses heat and prevent reduced braking performance. Tubeless ready out the box, pre fitted with quality tubeless tape and supplied with tubeless valves. High performance forged and CNC machined straight pull hubs roll incredibly fast and maintain speed with ease. Reduced lateral flex gives optimum power transfer. Precision machining and Japanese quality bearings offer incredible weather sealing and durability. The 6 pawl freehub engages with 36 tooth ratchet hub shell for ultra-fast acceleration, without affecting non pedalling resistance. Hand built with Premium Sapim CX-Ray Aero bladed straight pull spokes, widely regarded as the best spoke available. Amazingly lightweight with unrivalled fatigue resistance. We only build with Sapim’s premium corrosion proof brass nipples. Accepting a slight weight penalty over aluminium nipples but removing the inherent risks of corrosion prone and more brittle aluminium. Ride with confidence through the winter, and we think you will agree the few additional grams are worth it. Material: Toray T700/T800 carbon-fibre.
