DT Swiss

RR 521 700c Tubeless-Ready Disc Road Rim

The DT RR 521 Tubeless-Ready Disc Rim has the 32mm semi-aero profile of a traditional road rim, but with the 20mm internal width and construction of a traditional cross country rim for cross, gravel and adventure bikes. If you are going to use the DT Swiss RR 521 rim tubeless you will need DT Swiss 23mm Tubeless Tape and a 48mm tubeless valve.

When building the DT Swiss RR 521 rim you must use the included Pro Head Squorx Nipples and PHR Washers. DT Swiss calculates the RR 521 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.
