Fishy Posted October 13, 2006 Report Share Posted October 13, 2006 Hey guys, my bottom bracket is pretty buggered. I'm just wondering if there are any beefy square bottoms brackets? I have used the shimano one for a while, but they just don't cut the mustard now. Any ideas? Quote Link to comment Share on other sites More sharing options...

Matthew_Gibson Posted October 13, 2006 Report Share Posted October 13, 2006 Get an ISIS, they are a lot better! I used to have a sq taper, but it was creaking and making all sorts off noises. It wasn't cracked though? Got a ISIS No noise. Been very good for about 2 years. Quote Link to comment Share on other sites More sharing options...
narrowbars Posted October 13, 2006 Report Share Posted October 13, 2006 Hey guys, my bottom bracket is pretty buggered. I'm just wondering if there are any beefy square bottoms brackets? I have used the shimano one for a while, but they just don't cut the mustard now. Any ideas?Don't get isis. Due to the larger axel the bearings are made smaller and don't last.As for a square taper I would recomend the raceface taper lock in steel Quote Link to comment Share on other sites More sharing options...
trials_pimp Posted October 14, 2006 Report Share Posted October 14, 2006 Race Face BBs used to suffer from the bearing colapsing alot.Unless they have chenged themFor Square taper I would hightly recamend a Shimano UN52Cheap, and strong. Mine had lasted about 4 years and is still fine.I have only gone to ISIS due the the new frame (GU, came with an extra long ISIS BB the clear the brakes) Quote Link to comment Share on other sites More sharing options...
Fishy Posted October 14, 2006 Author Report Share Posted October 14, 2006 I don't really want to go isis, because I've just bought some cranks, looks like I'll be going for the raceface jobbie.Cheers guys Quote Link to comment Share on other sites More sharing options...
paolo Posted October 14, 2006 Report Share Posted October 14, 2006 I don't know if it's the same square tapper, but some 3 piece BMX cranks use square tapper. You could take the axle and external bearings cups. Quote Link to comment Share on other sites More sharing options...
Bigman Posted October 15, 2006 Report Share Posted October 15, 2006 Don't go raceface Joe!It will die quicker than a shimano, stick with either a UN52 like u had in there or go for a UN72 which is very similar but it has a steel non-driveside cup (where as the un52 is plastic) and a fully hollow axle, which doesn't affect the strength.Adam Quote Link to comment Share on other sites More sharing options...

No, it was still in the bike.) Plus I don't particularly like steel stuff going into an alu frame - it's asking for corrosion, especially in BB territory.Just bought a new 53 (successor of the 52), expecting it last til I flog or completely destroy the bike.Go UN53 - cheap as chips and pretty indestructible - I've never heard of anyone breaking one.
