Shimano BB-UN26 Square taper Bottom Bracket Review

Customer Ratings:

this BB is fine for onroad and light off road but it may be worth the extra 8 bucks for the UN54 which runs much smoother and is by far stonger.

This product was purchased because it is the reccommended bottom bracket for the the Alivio crankset that I reviewed earlier. I've read in some of the customer reviews that this product fails under heavy use. That really wasn't a concern of mine as my bike isn't ever subjected to heavy use. I use it mostly for short trips within my neighborhood. This BB is very smooth and it's easy to install if you have the proper tool. It's a perfect fit for what I use it for. It's also priced right.

Best Deals for Shimano BB-UN26 Square taper Bottom Bracket

In my old age, I have lost patience with loose ball bottom brackets and if they give me any grief at all, I yank 'em out and put in cartridge BB's like this one.

I use the ordinary Shimano ones like this and have never had a problem with any of 'em in the fifteen years I've been doing this on my own and others' bikes.

You do have to make sure you get the correct threading, shell width, and axle length, of course.This size, 68 x 123 mm, fits a lot of low end and mid-grade mountain and hybrid bikes but you need to measure to be sure.

Honest reviews on Shimano BB-UN26 Square taper Bottom Bracket

Ordered this to convert a triple crankset to a double crankset.

Other than the weight, which is to be expected at this price point, this is a solid bottom bracket that will work for years without any maintenance.

Bottom brackets shouldn't just break. Mine did.

According to the instructions on my bike, the bottom bracket was a Shimano. But when I pulled it, it was a different brand. Maybe that's why it broke?

The Shimano BB-UN26 is a pretty common cartridge on bikes. This one has a hard plastic locking ring/sleeve, which is my only complaint. Having said that, the plastic might allow for easier replacement on threads that are rusted or damaged. Just pay close attention to the instructions, because you do not want to add a petroleum product onto a plastic locking ring.

Pay attention to the direction of the threads!

If you have a torque wrench, use it. This is the 3rd time I've been able to use mine, and it felt good to know that I was torquing the bracket to the correct tightness.

Best of luck.
