Jack 80 mm review

I purchased two posts to use on Specialized Epics ridden mostly on Midwest singletrack. Install and setup was straightforward on both bikes, and did not require any additional effort other than minor adjusts at the release lever. The seat post is a well made and light weight compared to a rigid post.

The lever is a solid unit for a manufacturer provided piece. It has a nice shape with plenty of position adjustment.

After a few rides, I found this to a great component that works well. I does this job reliably with no additional thought. For the type of riding we have in this region, this is an excellent choice.
