The Deville has very limited chassis options and isn’t as stiff as chunkier forks, but BOS’s latest FCV damper offers incredible grip and support if you’re patient enough to tune it right.
With 34mm legs and no 29er or Boost options, this fork is looking dated. Despite cutouts in the skinny brace and obvious twist and tuck if you’re using a big rotor and bar, it’s still over 2kg too. The stepped 15mm axle system is beautifully machined to underline the premium quality and cost. There’s a 20mm axle kit too, but tyre/fender space is limited. The FCV damper has come from BOS’s rally experience via the Idylle DH fork. Get the balance of low and high-speed compression damping right and it opens up a fantastic mix of support for pushing crazy-hard through corners but ultra-sensitive traction to keep you railing no matter how random the rocks and roots get. It’s enough to make even an average tyre feel amazing and lets you stay head up, heels down and bar slammed even when you can feel the fork writhing all over the place. Finding this sweet spot isn’t easy though. A single click of compression can make a big difference and there’s no forgiveness if you get it wrong.
