Bombproof Bottom Bracket for Square Taper Cranks
These Shimano bottom brackets are a great deal and last for years and years and thousands and thousands of miles and can take a real beating. They're ridiculously cheap for what you get. Not too heavy either.Verified purchase: YesCondition: New

Perfect Fit
Was a perfect fit for my 2015 Diamondback Wildwood Classic bike. Smooth rotation. Installation was easy. Hopefully it will last considerably longer than the OEM bottom bracket cartridge.Verified purchase: YesCondition: New

Great
The only unexpected issue was, the cartridge threads in from the opposite side of the bike as my old cartridge did. Apparently this makes no difference. Observe the L and R markings on the cartridgeVerified purchase: YesCondition: New

Shimano BB-UN55
Yes, I know there are the UN26 and the UN54 in similar options, but those are only a few dollars cheaper and really not worth it. They have plastic parts which clearly don't make sense and the bearings are supposedly better. But these were definetly a good deal! Being only a state away from this bike shop, shipping was astoundingly quick! Great product, I will be making YouTube videos soon on these bottom brackets. And yes, these do have crank bolts which is nice of Shimano.Verified purchase: YesCondition: New

Sealed bearings - The perfect upgrade
This bottom bracket is a terrific upgrade from the old fashioned pair of bearings that are difficult to adjust and must be cleaned and repacked at least once per year, especially if wet conditions. I had to buy the special install/removal tool, but I am happy to expand my tool set in light of the advantages.Verified purchase: YesCondition: New
