Grantwrote a review of Schwalbe X-One Tubeless Tire on August 27, 2016
Familiarity: I've used it several times
Setup: Running these tubeless on HED Ardennes+ rims
I've done some drills and hot laps in the local park and these performed really nicely. Today I took them to a local park with trails that are very cx friendly. I put them through big open fields, wet grass early in the morning, some off camber turns, single track, roots, a few rocks, and some sand. These tires rolled fast when I needed it and gripped up great in the single track. They floated through the sand nicely as well (didn't get bogged down at all). And possibly my favorite part...they never got clogged up no matter where I went.
If you are looking for one cx tire to handle everything you've got to try these out.
Only downside - I seem to have a small lump in the front tire that hasn't smoothed out yet. I only notice it at 20mph on some pavement. Never noticed it on the trails.
