We've evolved our race-proven, aerodynamically optimised 40 Limitless Gravel rims into a rugged, ultra-endurance adventure wheelset with a SON 28 Dynamo front hub to provide reliable charging and lighting capabilities for long-distance ultra races, commuting and fast bikepacking adventures. Equipped with the dependable H_Ratchet rear hub, more spokes and brass nipples to keep riders pushing deep into remote terrain, bikepacking, or tackling ultra-endurance events - without sacrificing the aero advantage. 

Aero optimised for tyres over 40mm wide; work well with a 35-60mm tyre.
