Review on Enhanced SEO-optimized Truvativ Power Spline Bottom Bracket by Jason Rosekrans

I replaced my original Power Spline after about 6000 miles and 3 years. They are definitely different from ISIS; ISIS has 10 splines and a larger bolt hole, Power Spline has 12 splines. It arrived two days later with free cross-country shipping from BikeWorldUSA. So far so good, time will tell if it will last as long as the original. Of course it was nice and relaxed to cycle to work this morning. Installation was easy with the right tools and the price was under $20. Mine came with aluminum mounting cups and new screws. The instructions state that this BB is for off-road and on-road use only, not for mountain or downhill use.
