Bicycle gear specialist PRO (Nunspeet, The Netherlands) has launched what is claimed to be the fastest time trial wheel in the world. The three-spoke wheel is reinforced by Oxeon's (Borås, Sweden) TeXtreme spread-tow carbon fiber fabric and co-created with Team Sky (Manchester, U.K.). It was unveiled at the opening team time trial at the Vuelta a España.

"With the selection of materials, we've been extremely picky. We used a mix of high level unidirectional [UD] fibers and spread-tow fabrics. The outside TeXtreme layers have a double function. They keep the weight down and give a match in appearance with our rear TeXtreme disc wheel," says Leon Van Strien, product manager of PRO.

The PRO concept of co-creation has been applied on this wheel where the engineers at PRO, along with riders from Team Sky, have come up with the combination of materials used and its characteristics. Previous cooperation involved the PRO TeXtreme disc wheel.

Alongside the bike industry, current TeXtreme users can be found in Formula 1, Americas Cup, golf shafts, surf boards, aircraft interiors, rowing boats, skis, snowboards, ice hockey sticks, NASCAR and various industrial and advanced aerospace applications.
