monkey_pork Posted February 25, 2005 Report Share Posted February 25, 2005 Hmm, after no more than 40 minutes of very gentle riding my new FSA BB was cracking and banging so badly it was scaring people half a mile away. Stipping it out revealed that it must have started to break apart internally as it was weeping fluids everywhere and stank really badly [of machine oil] - not to mention the spectacular amount of play that the axle had now acquired. As I've had Shimano BB's abused horribly for hard xc, and grinding commuting jobs that seem to last for ages - 40 minutes seems just that bit too short to me, so I'm putting this one down to just a bad 'un ... but is there something especially fatal about trials riding to BB's I need to watch out for (or is it really like most things, and just down to how one rides)?

Will Arnold Posted February 25, 2005 Report Share Posted February 25, 2005 which model BB was it? cheers, Will Quote Link to comment Share on other sites More sharing options...
monkey_pork Posted February 25, 2005 Author Report Share Posted February 25, 2005 which model BB was it? cheers, Will ← Will, It was a fsa powerpro 7420. They are pretty much low-end BB's I fancy - and so, err, therein may lie the problem ... (Y)" Mark Quote Link to comment Share on other sites More sharing options...
ScotchDave Posted February 25, 2005 Report Share Posted February 25, 2005 For square tapers stick to shimano, for splined fsa or truvativ. Quote Link to comment Share on other sites More sharing options...
SebJT Posted February 25, 2005 Report Share Posted February 25, 2005 Which model? havent heard of that one... Do you mean a platinum pro? Ive have the ultimax extreme (worst fsa isis bb) and well thats has lasted fine for coming to 2years. No trouble with play or noise, feels a little stiff now but oh well i dont notice once cranks are on. Where did you get it from, really sounds like you have a faulty one i would look into having it warrentied... just dont say you did trials (Y) The FSA platinum pro is meant to be the best isis bb available. And for square taper, the shimano UN72... Seb Quote Link to comment Share on other sites More sharing options...

And for square taper, the shimano UN72... Seb ← It's a powerpro for sure. I'd say this one was just made badly, so I'm sure I can get it sorted under warrenty from my lbs - and from even a quick look at the rubbish way I was riding today I can quite honestly say that I don't ride trials. (Y) I've stuck a UN53 in for now (as that's all I could get today) (Y) ... so we'll see how well that one does (fine, I expect). On the plus side though', I did get to buy a new BB tool as my original one was pretty much done in. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted February 25, 2005 Report Share Posted February 25, 2005 Aaah, I see now... it was a square taper one? The Power Pro square taper BBs do tend to have a bit of a reputation (Y)" (Used to work in a shop where most of the Marin XC bikes were fitted with them, eugh) I've stuck a UN53 in for now (as that's all I could get today) (Y) ... so we'll see how well that one does (fine, I expect). ← Good choice sir - should last at least as long as your frame (Y) Quote Link to comment Share on other sites More sharing options...
monkey_pork Posted February 25, 2005 Author Report Share Posted February 25, 2005 Good choice sir - should last at least as long as your frame (Y) ← LOL - that could be read both ways ! (Y) but I know what you mean: thanks for the endorsement. The reason for the BB's compressed lifespan has become much clearer now too ... (being as it was indeed square tapir, err, you know, endangered, black and white, long nose etc, hmm, oh no hang on, being as it was square taper ...). Thanks too, to everyone who's commented.

Luke Drewery Posted February 27, 2005 Report Share Posted February 27, 2005 Ive had my FSA platinum pro for just over a year and its had some serious abuse. Its clunking quite a bit but its still rideable, i'd say their good bottom brackets though, you may just have been unlucky :turned: Quote Link to comment Share on other sites More sharing options...
aust Posted February 28, 2005 Report Share Posted February 28, 2005 the fsa isis bottom brackets are ACE! best bottom brackets going for isis. not too sure about the quare tapered ones though, i think you jsut might of pulled a bad egg out of the bunch ?
