Easy Installation
I bought this product after changing from a double crank set to a triple crank set. My original was 124mm and this Shimano was 113.5. I worked out great in helping to align my chain rings with my rear 8 speed cassette.. I should point out that, when installed in my 68mm frame, the left crank was slightly farther away than the right chain ring side from the frame. This worked out well for me because it helped to align my chain rings with the 8 speed cassette better. There were no problems with installation, it went into the frame smoothly. Much easier to install than the cup and cone bottom bracket I had before. As I look at the picture, it shows some kind of black washer on one side. I don't remember that on the one I received, and I wonder if that may be the reason one crank is slightly closer to the frame on one side....I don't know. Anyway, it works well.Verified purchase: YesCondition: New

The UN-300 is the best budget-friendly square taper bottom bracket available. If cost is an issue and weight isn't, this is a great choice.

very good but could be better
The thin left side cup is made of soft aluminum, splines of which deform to some extent while cup tightened to the proper torque. Otherwise well made and finished product.Verified purchase: YesCondition: New
