As well as being ridiculously light they have exceptional vibration damping properties resulting in a smoother, more comfortable ride.
Rider Weight Limit

Light, Aero Rims
When it comes to saving weight on a set of wheels, the rims are the place to start - this is where you feel the greatest benefit in speed and handling.
Lighter rims improve acceleration and climbing performance - they also improve the handling and overall agility of the bike, bringing the ride to life. Our Ultra rims are made with Japanese Toray T700 and T800 Carbon, using a toroidal aero profile to cut through the air. They measure 25mm at the brake track, widening to a maximum of 27mm.
Easy Fit, Tubeless Ready
Suitable for both tubeless tyres and clincher tyres with inner tubes – whichever you prefer.
Suitable For A Wide Range Of Tyre Sizes
Our rims are ideal for today's most popular road tyre sizes -they measure 18mm internally and are optimised for use with either 25mm or 28mm tyres. If you want to use wider tyres then they can be happily used with tyres up to 35mm
