THE NEW DEVILLE RaRe FCV enduro fork from French company BOS contains their latest tech innovation, the Frequency Control Valve. It’s basically an inertia valve inside their hydraulic cartridge and acts as a second damper, which is claimed to offer hugely increased comfort and control on rocky terrain, while also improving small-bump absorption.
The system is able to recognise whether compression inputs are coming from rider effort through the handlebar or impacts to the wheel. This should help the fork absorb square-edged hits better as well as improving tracking. Theoretically it’ll resist diving during braking but still remain active over rough ground.
Rebound and high and low-speed compression damping are externally adjustable. The fork has 34mm stanchions and is available with 150mm or 160mm of travel, just for 650b bikes at the moment. It weighs 2.01kg (4.43lb, 160mm model). Rob Weaver has just fitted the fork to his Yeti SB6c long-termer, so he’ll be letting you know how it rides as soon as he’s put some miles in on it.
