Description
As one of the UK’s innovators in aerodynamic wheel design over the last decade, it made perfect sense to enter the latest competitive cycling arena of gravel racing with the GX45 Aero—developed to deliver the fastest, most versatile gravel wheelset.
Aerodynamically optimized for 40mm to 45mm tyres, while remaining highly effective across the 35mm to 60mm range, the GX45 Aero combines proven aerodynamic efficiency with exceptional crosswind stability and a remarkably low weight.
This extra wide wheelset maintains sharp responsiveness and rapid acceleration, helping bridge gaps or launch attacks, offering a true no-compromise performance and a measurable advantage in the fastest and most demanding gravel races.
With a 40mm outer width and 32.5mm internal width, it allows the use of leading 40–45mm tyres such as Schwalbe G-One and Hutchinson Caracal, reducing system drag while lowering the risk of pinch flats.
At its core is the robust Evolve 300 hubset, rolling on high-quality TPI sealed bearings and featuring a proven 36t ratchet freehub system for lightning-fast engagement and long-term durability in demanding conditions.
