DT Swiss RR 421 asymmetric DB SBWT Presta-drilled disc brake black
- 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
- 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

- Outer width: 24 mm, Inner Width: 20 mm, Height: 21 mm

‘We invent, develop, shape and create, every day. We aspire to engineer leadership, every day. We strive for products that set benchmarks, every day. We help cyclists achieve their ambitions. Every day since 1994, engineering performance has been at the heart of everything we do.’
It all started with spokes. Formed in 1994 following a buyout from a Biel-based wire works with roots all the way back to the 15th-century, DT Swiss AG was founded by Frank Böchmann, Maurizio D’Alberto and Marco Zingg with the vision of becoming a world-renowned manufacturer of bicycle components.
Pioneers of the ratchet rear hub – which still sets the standard for engagement and performance – DT believes that wheels should be built with the entire system in mind, not just constructed from parts built by other brands. Every DT Swiss wheel is entirely made by the Swiss brand with hubs, nipples, spokes and rims all designed and built by them rather than sourced elsewhere.
In 2017 they launched the ARC road wheels, developed in conjunction with SwissSide and renowned aerodynamicist JP Ballard, and the latest generation of these wheels are currently ridden in the pro peloton by Lotto-Dstny and the likes of Caleb Ewan and Thomas De Gendt.
Today, DT Swiss is one of the biggest names in cycling and still strives to develop beautifully engineered products that break boundaries while setting the standard for quality control and reliability.
