DT Swiss RR 421 Asymmetric DB SBWT Disc Rim in Black

Brand:Dt Swiss

Code:VARRR421BLK

Want to run wider tyres without adding weight? the RR 421 offers a full 20 mm of internal width making it the perfect match for the latest endurance road disc brake bikes but weighs in at only 430 grams.

Asymmetrical rim profile is intended to counteract the off-set produced by using disc brake hubs, improving spoke angles and allowing for more even tension, strengthening and stiffening the wheel.

When lacing these rims, the offset should be towards the drive side on the front and away from the driveside on the rear, this allows for an optimal balance of spoke angles.

Can be run either with standard clinchers or road tubeless tyres using DT Swiss tubeless tape and valves.

Comes packaged with DT Swiss Squorx ProHead nipples and PHR washers to complete your build.

Strength Boost Welding Technology creates a perfectly welded join for a durable, reliable rim.

PHR washers and convex Squorx nipples naturally align perfectly with your chosen spokes, increasing stiffness and durability with no weight penalty over traditional eyeleted rims.

Features:

  • Unique process for the black coating produces a tough and durable finish
  • Suggested maximum system weight of 120 KG, those looking for 20 mm wide rim for heavier duty use are advised to consider the seriously robust RR 521
  • Presta drilling
  • Outer width: 24 mm, Inner Width: 20 mm, Height: 21 mm
  • ERD 601 mm with PHR Washers installed
  • Max spoke tension: 1200 N
