Overview

The Valence Aluminum Disc is an endurance road bike featuring a lightweight X6 alloy frame with carbon fork and steerer to deliver refined, long distance comfort and performance. An integrated ARC Endurance system delivers unrivalled vibration dampening, while the super stiff Power Chassis pedaling platform is the source of the bike's punchy acceleration and a highly responsive ride feel - rewarding riders who like to get up out of the saddle. Endurance geometry means confidence-inspiring stability and control at high speeds, while disc brakes provide incredible control in any conditions.

Leaving the house before dawn so you can crack a century before lunch. Every kilometre earned. The ride is an escape and the journey is everything. The pace is up to you.
