Hey, ive just ordered a T-Rex and wanted to know what bottom brackets you all run?  
 
On Tarty bikes it says recommended BB size is 73x128mm and i only have a 68x118mm will this work atall with a 22T chain ring? 
 
If not does anybody know where i can get a cheap one (like under £20) the right size? 
Also its square taper i need. 
 
jase.
