<h1>Rims</h1><i>We've pushed the boundaries and added even more width and depth for extra grip, low aero drag and low rolling resistance. 24mm wide and 31mm deep rounded profile rim made from an enriched alloy that builds into a sub 1500g wheelset. HFR+ alloy is a material that uses a heat-treatment process which delivers outstanding weight, stiffness and durability meaning rims can be wider and deeper for better aero performance and yet remain super-light for excellent climbing and acceleration.</i>
