The Kegel\'s capabilities are unmatched in terms of high speed and durability. The big 80mm diameter gives high speed rolls and the 56mm contact patch provides stability and versatility for traction and slide response. With the ability to cater for downhill riders thanks to the \"valley\" shaped cross section reducing weight the Orangatang Kegel is sure to be a firm favourite. The Kegel is poured in the Happy urethane formula. Tested and proven over the years in our 75mm In Heat and 70mm 4President race wheels, Happy thane has the ideal blend of grip, buttery slide consistency, and vibration damping for controllable and intuitive downhill performance.
