The Koryak, from Shimano’s finishing kit brand PRO, is reliable and relatively light, with useful remote options. But you can buy basically the same post in more variations, with a more secure saddle clamp, a fair bit cheaper. While there are collar and cosmetic differences, it’s basically the same as the Brand-X and Syncros posts, but with a single-bolt clamp on top. This is more awkward to finely adjust than the twin-bolt set-ups on its sibling posts and needs firm tightening to stop it tipping if you G-out on it. On the plus side, you can choose from a shifter-style remote (here) or a universal vertical lever, and while they both rattle a bit from new, they don’t get appreciably worse. The return speed is steady rather than speedy but there’s a distinct top-out clunk to tell you the post is extended and it doesn’t slow down obviously at low temperatures. It’ll stop anywhere in its stroke too, although the 120mm extension won’t be enough for a lot of riders/frames. Weight 613g...
