First glimpsed at NAHBS, ENVE’s new Mountain Fork is a rigid, carbon fibre design that shares all the industry leading technology and craftsmanship of the companies road and cyclocross forks with some innovative features thrown in. The tapered steerer (1.5”-1.125”) MTN fork has a carbon fibre mini-fender that has an integrated guide to neatly handle brake hose management without the hassle of internal routing. In wet or muddy conditions, the fender is just big enough to limit the amount that the front tyre casts off into your face. In dry conditions, the fender can be removed and replaced with pieces to fair in the attachment points and hold the hose in place. The other distinct feature is a two-position “chip” axle system. The rounded, rectangular chips fit into an eye at either fork tip. A 15mm thru-axle interface is machined into the chip off-center. With the axle in the rear position, the MTN fork has 44mm of rake (470mm axle to crown); the forward position gives 52mm of rake (472mm a-c). The a-c and variable rake make the MTN adaptable to a wide range of wheel sizes and frame geometries.
Why would you want a $625 rigid fork? Well, there are still riding conditions where a rigid fork will outperform a suspension fork, and even if your fork has a lockout, the MTN fork will steer more precisely while weighing perhaps less than half the weight (711gr with fender).
I kinda wonder if custom builders are going to jump on this item for monster-cross or big-tyre gravel grinders. The fork has 88mm of tyre clearance, much bigger than a typical cyclocross fork. The 470-472mm height is far taller though, so you wouldn’t want to retrofit this fork to a CX frame (395mm a-c seems to be a de facto standard for cyclocross forks). But I could slap this fork on my Giant XTC 27.5 and have an 18-lbs bike with more clearance and rubber than my CX bikes.
My daily shooter is Sony a9 with a vertical grip and various Sigma lenses attached like the 14mm 1.4 Art. Find more recommendations on our store page. As an Amazon Associate I earn from qualifying purchases.
