Rims
The Race Aero SuperDura has a 24mm wide and 31mm deep rounded profile rim from Niobium enriched alloy. Niobium alloy is a proprietary material and uses an advanced T10 heat-treatment process. The process delivers outstanding weight, stiffness and durability meaning rims can be wider for 25 and 28mm tyres, deeper for better aero performance, light for excellent climbing and acceleration and capably handle the increased loads and torque that more powerful riders can dish out. The wheelset utilises our strongest rim material in the tried and tested profile from our Race Aero Wide wheels. We've added even more width (24mm external and 19 internal) and depth (31mm) for extra grip, comfort, low aero drag and low rolling resistance advantage. It's also important to note that widening the rim increases the air volume for any given tyre size thus creating better shock absorption which is especially useful for higher loading/more powerful riders.
