420 Tubular

Is the 420 tubular rim designed for triathletes, time trialists, or road racers? All of the above. It's a multi-discipline performer with a fully toroidal shape inspired by the 1080 and Sub-9. The changes are subtle, but the results are not. At 30mph, the current 808 saves up to 7 watts over its predecessor without any added weight. This 81mm, 520g lightning bolt excels on any flat or rolling course.

Carbon Bridge™

Carbon Bridge uses a Kevlar® thread in a co-axial helix stitch to bind sheets of carbon to each other in our tubular rims. Because Kevlar is 350% more impact resistant than carbon, it can disperse shock more evenly throughout the carbon laminate, making for a rim that is practically bulletproof. In particular, Carbon Bridge reduces the vulnerability of the rim's tire bed, the area most susceptible to damage from impact. Read More
