If your looking for a rim that will hold up to the most demanding of trail rides don't buy these. After what I considered was a casual run through the woods I discovered that the rim was bent. I didn't recall hitting thing that would generate this type of damage. Terrain was not rocky. Contacted ITP and they suggested the only way the rim would bend is if my tire was under inflated. The tire was properly inflated and in my opion should not have bent under these conditions. ITP advised there was no warranty replacement for sport rims and suggested I go with the Baja. Did more research on line and discovered other riders were experincing the same problem with this rim being prone to bending.
