Any question answered...

i had read the sram manual and saw that there were no shims, but then keep reading users who mention theirs came with shims or that they have used shims

i posted on his blog today and he assured me he has actually tried a few different spacers on his BB to move the chain line around a little

it does not appear to be like the Shimano external bb cranks with the little clip part, to retain hold the cranks at a specific distance, clearly you could not shim the Shimano cranks in or out but it appears there is a little play with the Sram ones

James I prob still have the official SRAM ones you can have?
