“Not The Best”

The Good: Light weight, good rise angle

The Bad: Handle bar bolts loosen over time.

Overall Review:

Got this stem for a really good deal and was looking for a 31.8mm stem with a decent reach. I picked up the Koryak stem in a 80mm length. The stem went on easy enough and everything bolted up well. Followed all the torque recommendations prior to riding; handlebar bolts 4NM and steerer tube bolts 11NM. First ride everything went well. Second ride was good too. Prior to the third ride gave my bike a once over and checked bolts and found the front handlebar bolts of the stem really loose. I torqued them back down and after a couple of rides I found the same problem with the bolts loosening up. I do like the feel of the stem so I have continued to use it and just remember to give them a quick pre/post ride tighten to ensure they aren't loosening up to much. But because of this problem I wouldn't recommend this stuff anyone else. Hopefully the new Pro Koryak doesn't have the same issues.
