The Aero Ultra Disc SL5 String Spoke is built using Berd Polylight string spokes - the lightest spokes in the world.
As well as being ridiculously light they have exceptional vibration damping properties resulting in a smoother, more comfortable ride.
The Aero Ultra Disc SL5 benefits from an upgraded hub with premium ABEC5 rated bearings for speed, smoothness and durability. The patented offset 6 pawl freehub engages twice as fast as the standard version.
Rider Weight Limit
The rider weight limit on this wheel set is 110kg including the weight of bike and luggage.
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.
