myself Posted February 21, 2005 Report Share Posted February 21, 2005 Can you get the UCI tensiles in square tapered because on tarty bikes it says they are isis. If not then can someone please tell me what size isis BB i will need for a BT raven 4.0. Cheers :) (N) Quote Link to comment Share on other sites More sharing options...
Mark W Posted February 21, 2005 Report Share Posted February 21, 2005 No square taper, I'm afraid. Generally, you need a 127.5mm long BB spindle, then just whatever the width of the BB shell is on your bike. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted February 21, 2005 Report Share Posted February 21, 2005 ISIS only for the Tensiles (N) Depends what size chainring you're gonna run, but you can't go wrong with 128mm really - will definitely clear! Quote Link to comment Share on other sites More sharing options...

Fishwog Posted February 22, 2005 Report Share Posted February 22, 2005 Surely you would want to go for the shortest bottom bracket you could get away with? A longer bottom bracket is going to be weaker, and in theory the bearings wouldn't last aslong.... Quote Link to comment Share on other sites More sharing options...

I ran 113mm bb on a mod, the cranks hit the stays when ever you put some forse on them. its a pain in the ass, get get a long one just to make sure.

Have you ever broken one? Personally I'd go with the wider BB for a better choice of cranks/bashes/chainrings/frames if you do need to change. As for the bearings... there are 2 types of ISIS BB's - good ones and crap ones. The length has very little effect on how long the bearings will last.

Will Arnold Posted February 22, 2005 Report Share Posted February 22, 2005 OK, so you have the choice of an absolute minut increase in balance, or a better increase in strength, you like you ankle's in pieces? ← but with a long bb you have the piece of mind that your frame is not going to get dug into by chainring teeth anytime you do a sideways hop. with a shorter bb, you might not be able to transfer it across from one frame to another (Y) i have a 128mm truvativ giga pipe DH, its truely beasty! it aint gunna snap in a while, i would suggest getting one : http://www.chainreactioncycles.com/Models.aspx?ModelID=4981 but if tartybikes have any, then get them there :) Ta Will Quote Link to comment Share on other sites More sharing options...
