I started riding trails again and noticed that my 20 year old bottom bracket rattled a little bit. I removed the crank arms to inspect and found that I lost the bearing seal on one side. I can't say when this occurred or how much it influenced the bracket getting loose, but I figure after 20 years of riding it hasn't done so bad. These bottom brackets do actually come apart, even though they are presented as a closed system, and I was able to stop the rattle. But without that seal it wouldn't be long before I was having problems again. I was very pleased with how affordable these are and better yet how easy they are to install. I have been riding the new bottom bracket for a few weeks now with no issue and don't imagine I will have any for at least another 20 years.

Decent upgrade for loose spindle bottom bracket. Love the Shimano quality but hate the plastic cup.

    Comments about Shimano UN-26 Bottom Bracket:

    I refurbish bikes now that I'm retired. Many of the bikes I get in to repair have worn Bottom Brackets. Most are original equipment and not always quality parts. Some fall apart when they come out. I rely on the Shimano UN 26 to do the job well at a reasonable price.

            Recommended BB for crankset. Building up a Touring bike and needed an low cost BB that would work with a 48-38-28 crankset. This one works fine an should last.

              I had an x-mart bike that I pedaled the cheap bottom bracket out of. Installed this very easily. Bike is like new. For this price, it is a great upgrade. JensonUSA has always given great service.
