Giant's P-CXR1 wheels are a solid choice for race day, training rides, and just getting out there. Lightweight 24mm aluminum rims get up to speed quick, provide a nice tire profile for great cornering, and are tubeless compatible for increased traction with less weight and fewer flats. Giant's aluminum hub shells, with famous DT Swiss internals, feature six-bolt rotor mounts and interchangeable hub end caps for use on all your bikes, regardless of axle diameter or frame spacing.
