Our review

Smooth and swift and an ergonomic remote, but single-bolt post heads still aren’t as secure as twin-bolt
Pros: Smooth, stop-anywhere action, for the price; quality remote lever feel
Cons: Single bolt head isn’t secure or as easily adjustable as alternatives; slightly less travel than advertised

PRO’s Koryak post is now available with 150mm and 170mm (tested) of drop, in 30.9mm and 31.6mm diameters. Like on Fox’s Transfer post, the cable is clamped at the lever, not under the post. This makes it easier to install, but be careful to crimp the cable end securely, to avoid it fraying near your thumb.

The ergonomic under-bar remote lever is light and easy to operate. Weight is respectable, at 677g including cable and remote (an equivalent RockShox Reverb weighs 634g).

My 170mm sample only offered 162mm of measured travel, but that’s still enough for most situations. Be aware that the total extended post length is a generous 510mm, so it won’t fit in every frame out there.

The Koryak can be set to any height within its travel and its action is smooth and rapid, with no rotational play and perfectly acceptable fore-aft movement when at full height.

I had less success with the single-bolt post head though. After tightening it to the proper torque, it slipped when I was riding seated over a bump, causing the saddle nose to poke upwards at an alarming angle and with a loud creak.

Done up as tightly as possible with a multi-tool, this soon happened again. Adjusting the saddle angle is a hassle with this design too. I’d much prefer a twin-bolt post head.
