The prime rr 50 carbon clincher wheelset feature a 50mm deep aero rim profile to provide strong aerodynamic properties by reducing the amount of turbulence possible when the air meets the spokes the rr 50 wheelset combines this with a wider rim width profile creating an optimised tyre to rim interface to reduce rolling resistance and create a greater contact patch for greater stability in corners the prime rr 50 carbon clincher wheelset are hand built with the 7075 alloy bodied r020 hubset
