I've been running the X-11 radial, but those are not in production.
So I tried the X-lite.
A new X-11 compared to a new X-lite, the X-lite was much better. I recall the X-11 takes a bit to 'break in' so it deforms like when it has some time on it. The X-lite seemed pretty good right away.
I put the X-11 that I still had (new ) and will install on Enduro bike (AJP Ultrapassar) and used the X-Lite on my Trials (and trail) bike (OSSA Explorer).
Worked excellent in the first trial. Now I need to replace the front!
I don't know about durability yet- the X-11 lasted over 300 hours and still working. I exepect this to last shorter.
This is a very consistent and competent tire. I live in the high country and ride in mud, clay, sand,rocks, rivers and snow. This tire wears extremely well. The new side casing creates better grip. The wide knob spacings allows clay and mud to flick out. I used to run hard tires in summer and soft in winter. I now use this tire all year round. I have put aside the Kenda's, Dunlops
Bridgestones and Motoz, they are all good tires but do not have the all around qualities of the Star Cross 5 Mediums.
These tubes may be heavy but they are very strong. I ride only desert single track with lots of big sharp rocks and cactus and no flats yet. I'm a big guy 250+ pounds and I only run 12psi with these and no pinch flats.
Here is a top pro secret, almost every top pro team
uses a bib moose in the rear tire for the outdoors.
I have been using bibs in both front and rear for decades!
It's takes some getting use to, but if you ride "outdoors"
they will keep you safe from DNFs for years!
