DT Swiss
RR 421 Asymmetric Road Bike Wheel Rim (Disc)

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

• Comes packaged with DT Swiss Squorx ProHead and PHR washers to complete your build
• Strength Boost Welding Technology creates a perfectly welded join for a durable, reliable rim
