Shimano BB-UN55 Bottom Bracket British Thread is rated out of 5 by 11.Rated 5 out of 5 by fudgeroy123 from nice and smooth got this to replace the existing one in my carrera subway one . went in easy . had to twiddle the front derailier . the old out put shaft being a tadge smaller in length . the difference is astoundingDate published: 2017-11-30Rated 4 out of 5 by Deggo27 from BB-UN55 Bottom Bracket Not much to say, this replaces an RPM BB, which is of poor quality, the Shimano appears better manufactured. Comes with a sealing paste on the threads, so is well sealed and locks extremely tightly. All in all, a good product well made at a good priceDate published: 2017-07-17Rated 5 out of 5 by Tanalq from Great BB This is a great Bottom bracket. I did have one issue though. It didnt screw in fully. I had 1mm more to screw in. I was then told, that its not an issue although there are 1mm washers available. Would have been better if shimano could include those.Date published: 2017-05-09Rated 5 out of 5 by jack345 from bottom bracket un55 excellent BB gradually using on all my bikes one of the few using metal casing,easy fit,durable and therefore good build qualityDate published: 2016-10-19Rated 5 out of 5 by Nick95 from Bottom bracket upgrade After 2500 miles I thought the original bb was getting abit rough!! Bought this as an upgrade for obvious reasons.. Great brand, great value and price matched.. Very happy with results, only took 10 mins to swap over.Date published: 2016-09-21Rated 5 out of 5 by Steve1000 from Excellent bottom bracket, excellent price Halfords were running a price match on this product, and it was easy to order and pick up in store. Guy in cycle department was very thorough - he went through the details of the cartridge to ensure it was the correct one.Date published: 2016-06-24Rated 5 out of 5 by dj1014 from Great Item This was bought to replace old type bearings on a vintage style bike, which kept wearing out. It was easy to fit and the bike now pedals smoother than when new.Date published: 2016-02-22Rated 5 out of 5 by luic from shimano BB I have used it for 2 weeks, so it is 2 early to talk about durability. It has behaved well, as expected, being a shimano part. Changed bekos the original one was making a tek noise at each pedal stroke, but I think it only needed tightening. Since I had opened it all I decided to put a shimano one. Only thing is that the splindle size is half mm smaller than original (122.5 instead of 123), so requires a little adjustment on cable and stoppers. Chainline change is negligible.Date published: 2015-11-26
