Review on Enhanced SEO-optimized Truvativ Power Spline Bottom Bracket by Gene Rosado

I don't know why some people are reporting that these bottom brackets aren't durable. I hope they haven't started making them cheap. I've had to convert all my bikes from cartridge bearing bottom brackets to free bearing models because I always burned them out within a few weeks. Newer models of hanging cups are the worst. Regardless of the brand (Campagnolo, Shimano, SRAM, and numerous no-name models), cartridge bearing design seems to be misguided. An exception is the Truvativ Power Spline sled. I went through two in eight years. I use them on my fixed gear commuter bike that I ride at least 75 miles a week - whatever the weather. The first failed about three years ago when I was using a rigid gear for commuting and exercising, and I've survived about a dozen downpours this year. I rode 150 miles a week for 2 of those 3 years. Finally there was a slight click. I could soak the block in motor oil, then drain it and it would last another week or so. but in the end I just replaced it. I recently bought a new set of fixed gear frames and decided to replace the old Power Spline with a new one. The old one is fine, it just wouldn't screw into the frameset bottom bracket shell easily and I had a new one in the shop. based on the branding of the new one I just ordered so I have a spare). So it's not IS. This is a more conical view. The whole Power Spline concept never caught on (something like Shimano's Octalink. Yes, I tried that too) so it's not clear how much longer they'll be making them. However, you must use Power Spline cranks with them. As mentioned, this is nothing special to watch out for. They don't seal particularly well or go super smooth out of the box. but in my experience they have proven to be very durable and that makes all the difference.
