BOS Deville FCV fork


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.

KONA SHRED

With a reputation for no-nonsense ruggedness and a background in the always progressive and punishing riding of Canada, Kona have been building hardcore hardtails for longer than almost anyone else. The Shred is the most expensive bike on test but it’s a proper trail tank.

Nukeproof Vector AM Comp Cro-Mo saddle

The Vector AM is pretty race focused, with minimal padding. There’s a deep (if narrow) pressurerelief channel to keep the blood flowing where it’s meant to. Used with bib shorts, we found it pretty comfortable for shorter rides and suffered no pain or discomfort in the central region. On steep climbs the slightly downturned nose provides a reasonable forward perch, while the svelte profile and smooth edges make it particularly unobtrusive when moving about on the descents. It’s quite stiff though, and can feel harsh on long rides or bumpy ground. We definitely wouldn’t want to spend much time on it without a chamois. It’s heavier than we’d expect for such a lightly padded perch too. There’s a lighter Pro version with titanium rails for $105, but at 241g it’s only 10g lighter. Weight 251g Price $67

GT Zaskar Evolution

While some bike models last just a couple of years, others change with the times to stay at the top of riders’ wishlists. In the second part of this series looking at the evolution of bikes that enjoy enduring popularity with UK riders, we turn to the GT Zaskar – a bike that was at the forefront of our sport for a long time and still has plenty of appeal today.

Cannondale Trail SL 29 SS

The fat aluminium tubes are a constrast to the skinny items seen elsewhere in the test, but this rigid Cannondale uses them to create one of the most old-school - and lightest - rides here.

CANYON NERVE AL 8.0

  S ince their entry into the UK market a few years ago, Canyon have made a name for themselves as purveyors of well-made bikes that exhibit often extraordinary value. The secret (or catch, depending on your point of view) is that the brand don’t have dealers – they ship bikes directly to your door.
