Born from racing, BoXXer Ulitimate promises one thing above all—composure. By eliminating chaos before it reaches the rider, every run delivers predictable speed, traction, and control. The all-new LinearXL air spring provides a coil-like ride—supple off the top, supportive through the mid-stroke, and backed by a jounce bottom-out bumper for confident end-stroke control—giving you unwavering consistency and predictability. Found only in our Ultimate forks, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth performance throughout the entire service interval. Intuitive HSC/LSC controls on the Charger 3.2 damper with ButterCups technology make setup fast, understandable, and easy to communicate. You’re so composed you don’t realize you’re going faster. But the clock says it all.

Went with the rival setup instead of force and I am super happy that I did. If you don’t need the extra button on the hoods, these are probably the best value item in the AXS drivetrain.
The S-Works Prevail 3 is one of the most comfortable bike helmets I’ve worn. The fit system adjusts perfectly, and once I ratchet the MIPS cradle to my head, the helmet almost disappears — it conforms so well that I barely notice I’m wearing it.
Ventilation is excellent. Riding in moderate weather around the mid-70s, my head stayed cool and comfortable without overheating. The airflow design really works.
Thankfully, I haven’t had to test the helmet in a crash, and I hope I never do. But the build quality and design give me a lot of confidence in the protection it offers. Highly recommended.
