From Reed Boggs: Stan’s NoTubes released a new line of rims, their first asymmetric aluminum rims- the MK4’s. We decided to put them to the test in mountain bike paradise, Virgin, Utah. The Shire dudes and I built a line to test the strength & durability. I think it’s safe to say, the MK4’s handled it.
