1337 Trials Posted April 4, 2012 Report Share Posted April 4, 2012 (edited) Hello. I noticed one of my Bottom bracket cups has cracked so im looking for some new cups. Im not big hardcore mountain biker anymore and I just use the bike to get around on really. Would some shimano cups for £15 do the trick or should I pay a little extra and go for £20-£30 cups? EDIT: I need the external cups http://www.chainreactioncycles.com/SearchResults.aspx?Search=bb+cups Edited April 4, 2012 by 1337 Trials Quote Link to comment Share on other sites More sharing options...
trialsmax04 Posted April 4, 2012 Report Share Posted April 4, 2012 My link The deore ones are alright.Mine lasted for a few years, my dads lasted a few weeks. Guess its luck of the draw. The SLX/XT bb's are also good. Mine lasted about a year, with a good few thousand miles on it. Or for the same price (£24) Go on ebay and grab a Shimano XTR one. Ive just strapped mine on today, and is smooth as silk. Quote Link to comment Share on other sites More sharing options...
haydon_peter Posted April 5, 2012 Report Share Posted April 5, 2012 Agreed, Shimano BB's are bomb proof! I have run external Shimano BB's (XT and Saint) on my XC and DH bikes for years, I seem to get a good couple of years out of them depending on conditions etc... I'm not sure if there is actually any difference between the bearing quality of Deore compared to XT or whether it is just lighter cups on the XT offering. From what you have said I would just go with the Deore BB Quote Link to comment Share on other sites More sharing options...
1337 Trials Posted April 5, 2012 Author Report Share Posted April 5, 2012 (edited) So I may as well just buy a whole new BB rather than just the cups? Surpose I may as well get it all done now as ive had that BB for a long time and its a pain un-doing bolts to do with the drivetrain. http://www.ebay.co.uk/itm/Shimano-Saint-HollowTech-II-BB-bottom-bracket-68-73mm-BB80-fits-XT-XTR-SLX-/270944601761?pt=UK_sportsleisure_cycling_bikeparts_SR&hash=item3f158e86a1#ht_500wt_1416 Edited April 5, 2012 by 1337 Trials Quote Link to comment Share on other sites More sharing options...
haydon_peter Posted April 5, 2012 Report Share Posted April 5, 2012 The Deore, XT/SLX and Saint you have just linked to, will all come as complete BB's. You will get the cups with bearings pre-fitted, the plastic tube that sits between the cups and the BB spacers to go between the cups and the frame. It is awkward to replace just the bearings so you replace the cups and bearings in one go. Quote Link to comment Share on other sites More sharing options...
1337 Trials Posted April 10, 2012 Author Report Share Posted April 10, 2012 I think I forgot to mention the most important thing. They are Truvativ Howitzer cranks/BB. Im having trouble finding the BB cups alone and the Howitzer BBs are quite expensive. Im thinking may be just bid on a second hand one on ebay for the cups Quote Link to comment Share on other sites More sharing options...
bing Posted April 10, 2012 Report Share Posted April 10, 2012 think the bb is specific to the axle. go on pink bike, there is loads for sale on there Quote Link to comment Share on other sites More sharing options...
Matt Vandart Posted April 10, 2012 Report Share Posted April 10, 2012 you can get conversion spacers so you can run shimano bb's with truvativ cranks Quote Link to comment Share on other sites More sharing options...
haydon_peter Posted April 10, 2012 Report Share Posted April 10, 2012 A quick google seems to agree with what has already been said. Truvativ and Shimano use different sizes but you can get adaptors so Truvativ cranks can be used with the Shimano Hollowtech BB's. I'm not sure what the newer Truvative BB's are like but I owned a few quite a long time ago and they died very quickly whereas the Shimano BB's I have owned since have all lasted ages...

1337 Trials Posted April 11, 2012 Author Report Share Posted April 11, 2012 (edited) Ile have a look at shimano BB's then. If I can get the BB and the adapters for £30 ile be chuffed! PS. I just read you can get Truvativ -> Hope adaptors and there is no way im paying over £60 for a BB as I only really ride the bike lightly now.
