I decided to use the Shimano XT external bb cranks from my mtb but I have a bit of a problem with the chainline.
With the chainring fitted in the middle position this gives a chainline of 50mm but the middle of the rear cassette is 43,5mm.... This gives a pretty shitty chainline. And I don't really understand it, normally on MTB's the middle ring should line up with the middle of the cassette right?
