PaRtZ Posted September 7, 2009 Report Share Posted September 7, 2009 Now somehow the bearings in my neon BB have started creaking yesterday. In its defence I was fannying around with the cups etc because my tool doesnt clear it and had to devise a very random method but anywayWith prices off BB's going higher, I was just wondering if its worth buying a cheaper BB ie onza to a more expensive one ie tryall. It needs to be as wide as poss for crank clearance and Im not too bothered about how freely it spins. I just want it to last! Quote Link to comment Share on other sites More sharing options...
Adam-Griffin Posted September 7, 2009 Report Share Posted September 7, 2009 I'd say no for Isis, Yes for Square taper. I've Never had any problems with any cheap Sqaure bb although i Bought a cheap Vp Isis one of Ebay at the same time i bought my Fsa. The Fsa is still going strong to this day where as the Vp was dead within 2-3months of light riding. Quote Link to comment Share on other sites More sharing options...
Alex Dark Posted September 7, 2009 Report Share Posted September 7, 2009 Unfortunately, due to the tiny bearing size on an isis bearing bottom bracket, far higher grade bearings have to be use when compared with sq. taper. Thus driving the price up to around double or even triple of square. Quote Link to comment Share on other sites More sharing options...
eskimo Posted September 7, 2009 Report Share Posted September 7, 2009 Allot of people seem to like SKF BBs. The SKF BFR-600 on Tarty is 128mm, so maybe worth a shout/ search? Quote Link to comment Share on other sites More sharing options...

I've Pro2, Profile and Eno. I prefer rear drive in every way when ignoring the pickup of an Eno. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted September 7, 2009 Report Share Posted September 7, 2009 I'd say no for Isis, Yes for Square taperExactly what I was gonna say Unless you get a pretty hefty ISIS BB such as the Because, that will last well. Quote Link to comment Share on other sites More sharing options...
Mark W Posted September 7, 2009 Report Share Posted September 7, 2009 Speaking as a veteran of many Onza BB snaps: No. If it's square taper, just invest a bit more. I haven't bought a square taper BB since 2005 or so, so I don't fully know the score, but the majority of Shimano UN-53 BBs (Or whichever number they were) are pretty rad. I didn't notice any real difference bearing wise between the Onza and the Shimano ones, but the spindle snapped on my Onza BB reasonably quickly - haven't ever killed a Shimano one though.

forteh Posted September 7, 2009 Report Share Posted September 7, 2009 (edited) I cant comment on BB axle snapping as Ive never done it, Ive always used UN72 or UN53 (old XT and LX) BBs, personally I wouldnt want to trust a cheaper 'generic brand' BB unless I had no option. Ive only ever had bearings fail on shimano BBs.Im now using hope ti square taper and I cant honestly see it failing with my riding, its the same dimensions as the UN72 but with a far stronger axle, the square taper interface works perfectly for me; Ive never used ISIS Edited September 7, 2009 by forteh Quote Link to comment Share on other sites More sharing options...
psycholist Posted September 7, 2009 Report Share Posted September 7, 2009 I had to switch to ISIS after I started snapping XT (UN-72) BB's after about a year's use a few years ago. I've used a ISIS BB's since I bought one second hand with Middleburns in 2005ish and had no axles snap yet. For everything except trials and possibly DH I'd recommend XT square taper for durability as the bearings last for years. If you snap square taper axles you've no choice but to go for a ISIS axle. My Echo BB has been running flawlessly for 1 3/4 years so far... I think the Echo design gets around the requirement for small crappy bearings by using the axle surface as a bearing race, allowing nearly square taper sized bearing to fit.

LukasMcNeal Posted September 7, 2009 Report Share Posted September 7, 2009 I must say I know I only payed £11 or whatever off of tarty for my trialtech St bb I'm rather disappointed I fitted it a month ago and it's already creaking !

Mark W Posted September 7, 2009 Report Share Posted September 7, 2009 That's because you need to grease it and/or tighten it. Most new BBs need tightening up after a week or so, and you can never have too much grease on the threads/tapers. Quote Link to comment Share on other sites More sharing options...
Dale-Hill Posted September 7, 2009 Report Share Posted September 7, 2009 My FSA BB was creaking other week, took it off re greased the threads did it up super tight, perfect now Quote Link to comment Share on other sites More sharing options...
