Being an avid MTB'r, and someone who takes pride in their bikes and equipment, I was looking for a more reliable and longer life replacement for my bikes bearings and bottom brackets. Training and racing MTB in all types of conditions, from mud, rain, rivers to dry, dust, and sandstone based environments seem to take a heavy toll on my bearings and bottom brackets in particular. Even with my bike being serviced and cleaned regularly I was using 2-3 bottom brackets a season, not to mention the creaking that becomes evident as they approach the end of their useful life.
