flas12345 Posted February 27, 2007 Report Share Posted February 27, 2007 i think they are something like 73mm cup sizes. if you are going to get a new bottom bracket i would get a truvativ giga pipe. they are amazing for the money and will last you ages. i know that tartybikes ar selling them at £35 which i think is a bargain, but its up to you what you get really.cheers lou.

Mod Man Leo Posted February 28, 2007 Report Share Posted February 28, 2007 i am very sure its a 73mm-113mm BB, but if its wrong, i not to blame hope it helped. Leo Quote Link to comment Share on other sites More sharing options...
smellthecheese Posted March 1, 2007 Report Share Posted March 1, 2007 I had the lime green 2003 gt moto, it had a 73mm shell. As for axle length, it all kinda depends what cranks ur puttin on i.e. tripple ring or single etc Quote Link to comment Share on other sites More sharing options...
