The XR 421 is the new alloy cross-country rim from DT Swiss, replacing the XR 391. Whether you're going for your fastest lap of the local XC loop or chasing your mates, it's designed to give you confidence when you need it most, lap after lap.

It's made from DT's premium aluminium alloy with a precision-welded joint, and the lightweight asymmetric construction evens out spoke tension between the two sides of the wheel for a stronger, longer-lasting build. A flatter profile and wider bead hooks improve impact resistance and help protect the tyre.

The 28mm internal width is optimised for tyres up to 2.7" wide, so it supports the latest wide XC race tyres as well as tougher trail rubber for rowdier rides. It comes in 29" with 28 spoke holes, supplied with black DT Squorx nipples, PHR washers and chrome, black and gold decal sets to swap with the standard red decals.
