Sram MTB 00.6415.045.070 BB GXP Team Cups English 100 (GXP Fat Bike), Multicolor

Wasn't the right length for my 2013 Whyte t129 SCR so had to use the existing tube but the two outer bearing houses are spot on.

Great Product

I find these last about four to six months on my bike. They start to seize if the bike has been sitting for a while and when you free them off they are a bit rough. I've never had one on a bike long enough to develop any significant play. I have tried regularly popping off the seals and relubricating and this does extend the life a bit but not hugely. The bearings seem to get water inside and I'm not sure why, I don't use a pressure washer in that area. I do live in the Scottish Borders so perhaps it's just all the muddy puddles. I've tried more expensive BBs and have had them last longer but the economics don't stack up. I do feel guilty but at this price I'm happy to just bung a new one in every four months or so.

Poor quality play in bottom bracket buy a 3rd party one instead or fo shimano

Nicely priced.

was bought to replace current bb took it to my local bikeshop works as it should

I work as a bike mechanic. All of these entry level external bb's are about a 6 month working life, which is fine if you have Shimano ones at £12 each, but SRAM cost twice that, so it gets 3 stars for costing too much for a throw away part. Personally I'd fit a wheels manufacturing one with replaceable bearings... Costs more but will last 3 times as long and be repairable.

Not the best BB you can buy. I seem to kill them within six months or 2 or 3 multi day off road session.

Movimento centrale ottimo

This part fits my fat bike perfectly. After a month of use, I have no complaints.

Confiable

Lo que buscaba

Work perfectly for a replacement bearing. I needed it for my narrower bottom bracket, so I reused my narrower tube and used the bearings.
