Whats the difference between these bottom brackets? Its the 68mm by 113mm that i need but was wondering what an e type bb is.Its quite a bit cheaper but dont know if it makes a difference .Any info would be appreciated

E type is for use with an E type mount front mech or with a chaindevice, if you intend to use one without the mech/device you'll need to space out the drive side about 2mm-ish
E-type is a kind of front mech, oddly enough mounted arund the BB with a sticky-up thing that the main bit attaches too, like this [img]

Also, don't buy it from CRC, their warrenty service is rubbish
Probably better going for the non e-type then. Thanks anyway
Won't do any harm running an E-type, why not save the money?You can get the required spacer from any bike shop, they come with HT2 chainsets and are not always used. We've got loads kicking around,will give them away if the customer's buying something.
