The small world of mtb suspension is governed by the modes and commercial arguments. Those who win the OEM (understand original equipment market) are also often those who manage to impose their “way” on the after market. Fox and Rockshock lead on middle and high-end, Suntour almost on the rest of the range. Some brands like Marzocchi ( who was in financial difficulty), but offers performance products, and « emerging » players such as X-fusion, manitou, white brother, Fournales, Magura, and DTSwiss formula and DVO take the rest of the cake.
In this universe, BOS, a French company created by Olivier Bossard, a defector from the heyday SUNN for which he was responsible for the design office at the time that the product team jewelry and technologies that remain unsurpassed to this day . Today also very active in the automotive, BOS remains a benchmark in the world of mountain biking, with products apart.
We had the chance to test both the more accessible of these products, all-mountain fork / enduro, the Deville and the damper bound Vip’R. Both products are exceptions on the market in many ways, to begin their higher price, but also by technological approach.
Bos Deville, go to hell with that gadgets devil!
Behind the pun comes down a little easier in some ways the philosophy of Deville TRC. Note that we tried a 140mm travel model and standard pivot 1 1/8 right which corresponded to our test program and the test platform. We will pass the details of installation are all that more standard. Small detail, Deville has the tee with a notch handy to pull the headset ring avoiding ruining the paint. The fork offers a range of full adjustment, hydraulics slow / fast rebound, air spring preload and TRC. The fork is built with 34 mm stanchions and 20 mm true axle with a specific quick release (and thoughtful)
The primary sensations when trying a new product as complex as a fork to understand upscale moreover, are either misleading or immediately excellent. In the case of Deville, we had to take our brands. The first sensation that is perceived rigidity is important, it shows a sense of precision front confusing. In reality, it takes a little time to understand where does this impression come from. Is the stiffness or the geometry of the platform with? The answer came after (some) kilometers on backgrounds. Always at first, depreciation needs to be identified, and because its operation is so constant and linear as is expected with a sensation of diving here is very diminished, if not non-existent. Yes, unlike the competition depreciation is here given to the hydraulic and pneumatic spring, not that it plays perfectly its role as guarantor of the attitude of the bike. In fact no matter what happens and no matter what stage you are in, the bike maintains a nearly constant basis and therefore its geometry.
The result is that ultimately it is surprising to pass quickly, much faster in places where before you would not have thought to do. Why? The sensitivity and responsiveness of the hydraulic fork is such excellent that reading the field and therefore literally glue the wheel to the ground addressing the roots rocks and other rough terrain. Any adjustments as a significant effect on the fork. In short, a product that deserves further tested and linked to the damper Vip’R you’ll find in All-moutain magazine on iPad in a very short time on the Appstore.
