Average Reviews:
(More customer reviews)My bottom bracket was wearing out fast. There was lots of "play" in the crank, and when I pedaled hard, it felt sloppy and made a clunky noise. I took my bike to a shop to have the bottom bracket repaired. They must have taken it out and worked on it, but I suspect the original was not a sealed bracket. They did a nice "tune up" of everything else, but only tightened the bottom bracket instead of replacing it. I didn't realize this until I got home and rode it. It was not good enough.
So I decided to do it right. You need an extractor to remove the pedal arms. (It's a kind of gear-puller.) You also need a special socket to loosen up the old bracket, and maybe a good pair of channel locks or vice grips, depending on what's holding it all together. On my bike, I had to turn BOTH SIDES FORWARD to loosen the bracket. (I learned this the hard way.) It rides like new now. I even replaced the bottom bracket on my step-daughter's bike. Remember to tie the bike off the ground, right side up (to some garage rafters, maybe) in order to make it easy to work on. You'll need to measure the overall length of the bracket, to the outer edges of the square ends of the shaft, and the inner length of the cylinder, to get the right part. Make sure you get the right one. Ask a bike expert if you need some help. I did!
