ax-lightness SELECTION 45CX - Durable full-carbon clincher wheelset for gravel, cyclocross, and extreme sprints
ax-lightness has leveraged its many years of experience in carbon construction (wheel building) to develop the new carbon rims of the SELECTION series. The SELECTION wheel series offers outstanding performance at a fair price-performance ratio.

The SELECTION 45CX brings more aerodynamics into play without sacrificing all-around potential. With a 45 mm rim profile height, 30 mm outer width, and 24 mm inner rim width, it offers significantly improved aero performance compared to the 35CX, yet remains easy to handle with a weight of 1250g. Thanks to the flared rim shape, it offers high crosswind stability, while the Sapim CX-Ray spokes with external spoke nipples ensure easy serviceability. Ideal for racing on the road, in endurance events, and on demanding gravel routes.

The in-house ax-lightness disc hubs with CenterLock mounts used in the SELECTION series are top-tier; the rear hub features a sealed freewheel with a ratchet system. The overall focus was on maximum stability combined with reduced weight. High-quality Enduro hub bearings ensure low friction losses. The double-crossed spoke pattern, with 24 Sapim CX-Ray blade spokes per wheel, distributes the load evenly across the rim and results in extremely stiff and durable wheels. All wheelsets in the SELECTION series feature external spoke nipples. This simplifies maintenance without the need for time-consuming removal of tires.

The weight, including tubeless rim tape, is just 1250 grams (±5%), making the SELECTION 45CX the perfect all-rounder with a top price-performance ratio—for road, gravel, and cyclocross alike.

The wheelset demonstrates its racing capabilities with the Continental Team BENOTTI Berthold.
