RR 421 700c Tubeless-Ready Disc Road Rim

The DT RR 421 Tubeless-Ready Disc Rim has 21mm asymmetrical shape of a modern road rim, but with the 20mm internal width and construction of a traditional cross country rim for road, cross, gravel and adventure bikes. If you are going to use the DT Swiss RR 421 rim tubeless you will need DT Swiss 23mm Tubeless Tape and a 48mm tubeless valve.

When building the DT Swiss RR 421 rim you must use the included Pro Head Squorx Nipples and PHR Washers. DT Swiss calculates the RR 421 ERD of 581mm with the washers in place. Instructions for installing the Squorx nipples and PHR washers can be found here. You will also need a DT Swiss Squorx nipple wrench for building and servicing of these rims/wheels.

For more even spoke tension, the DT Swiss RR 421 Road Disc Rim has a 3mm offset and asymmetrical rim profile.
