Luke Drewery Posted July 12, 2005 Report Share Posted July 12, 2005 Right, I recently got myself a t-rex frame and I am having trouble finding a good bottom bracket that allows my 22t middleburn pro trials ISIS cranks to clear the chainstays. Adam@tartybikes has already recommended one but you have to run spacers on the drive side so there are less threads in the frame. I was just wondering what other people run with 22t ISIS cranks? I was looking at the try-all one on bikedock, but it is seriously overpriced and i dont know if it will even fit. So anyone running a t-rex frame and a 22t chainring please post up here hat you are running so i can get an idea of what is available. I have looked around but cant find any 73 by 128mm bb's anywhere that are ideal. Any help would be very much appreciated, cheers (Y) Quote Link to comment Share on other sites More sharing options...

Luke Drewery Posted July 13, 2005 Author Report Share Posted July 13, 2005 Anyone? surely someone has to run a 22t chainring on a t-rex? Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted July 13, 2005 Report Share Posted July 13, 2005 steve-o tried his very best with muscleman cranks, and the tensile screw-on bash + 22t ring combo. We tried a 127.5mm BB axle and even 4mm worth of drive side spacers but the ring rubbed on the chainstay. He bought a 20t ring from CRC and managed to get it to fit. When he came to take it off though, he may have bent the ring slightly, but it had rubbed a wee grove in his chainstay. Nothing major, just a bit miffed really. He's got front freewheel now.... You may have more luck with isis stuff, i don't really know.... good luck! adam Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted July 13, 2005 Report Share Posted July 13, 2005 Anyone? surely someone has to run a 22t chainring on a t-rex? ← Yep, me :P With the setup I described to you (Y) Quote Link to comment Share on other sites More sharing options...
Shaun H Posted July 13, 2005 Report Share Posted July 13, 2005 Just so I don't have to start a new thread, could someone tell me what size BB i'll need with a t-rex running an ACS claw 18t on echo cranks? Apologies for sort of hi-jacking the thread. Quote Link to comment Share on other sites More sharing options...
zoojames Posted July 13, 2005 Report Share Posted July 13, 2005 Im running a square taper bb 127.5mm with 22t chain ring and middleburn cranks. So yeah...I don't know why an isis bb would make a difference (Y) never got round to using one. Too much money to change cranks etc! James :P Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted July 13, 2005 Report Share Posted July 13, 2005 (edited) shaun...and anyone else (Y) (this isn't the first time.....) Anything to do with a BB on a t-rex involves 127.5mm nothing else seems to work without muchos effort (or at all) adam EDIT: and before someone corrects that....if isis, 128mm :P" Edited July 13, 2005 by ad101 Quote Link to comment Share on other sites More sharing options...
