Very happy with the Tubes so far.
I recently purchased a front and rear set from Slavin's Racing and have installed the rear tube and will install the front when the tire needs replacing. I rode the new tube for about 35 miles of medium enduro (CO Western slope high rocky desert). So far the bike rides great. I was worried the added weight was going to make my 300 XCW feel sluggish or I would notice a difference in the rotational weight making the bike less nimble. The best I can tell, my bike felt great and the low psi (I ran 5 psi) made the traction comparable to the Tubliss system I had been running for years. I am pleased with the purchase so far and I am hopeful that the system will last several tires.
