Not very easy to implement. The supports are too thick; they touch the clamping screws of the bolts already on the ATV (derailleur clamp) result I can tighten, at most one-third, the screw is in cantilever. Furthermore we still have forcefully insert the bars in the body of the V rack. This should work for a lot of bicycles, but not all, beware if you have a real mountain bike, choose bars (the bars V) thinner.
