BOS RaRe FCV enduro fork


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.

Price 1500$

Merida Big Nine 100

Wit the bikes swapped over, we head out on the same loop again, this time on the 29in Big Nine 100. Whereas the Big Seven was snappy off the line, the 29er takes a couple more pedal strokes to get up to speed. That said, once it's up there, it's easy to keep the big wheels rolling, allowing us to cover ground with ease. The fire road is at times a little rough, and the bigger wheels roll over the imperfections so we barely notice them.

Chromag HiFi 35 (50mm) stem

This is a seriously solid stem. Chromag use 5mm Allen bolts throughout, which makes it that bit easier to fit because you don’t have to swap tools. Once torqued up to the recommended 6-8Nm, it clamps both steerer and bar solidly, with no appreciable flex. We couldn’t get it to twist on the steerer, either in our static test or when riding. It’s also available in a 35mm length and three other colours. At 204g the HiFi is the heaviest stem on test by some margin, despite being one of the more expensive offerings here. Price $112

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.

Trek Session Evolution

In this series we’re looking at the evolution of three bikes that enjoy enduring popularity with UK riders. Each fits into a different category – we’ve had a hardtail and a full-suspension trail bike, so for this final feature it’s the turn of the long-travel bike. And few ‘big bikes’ have undergone such a transformation as the Trek Session, which had a bit of a confused birth at a time of overlapping disciplines but has evolved into a sleek, lightweight race bike with multiple World Cup wins to its name.
