New to all this stuff and i guess this has been covered many times.....an answer to this is gratefully received
I have a GT Zaskar & and am changing the worn , unidentified cranks to Race Face Turbines with Race Face team chain rings.
using the 'generally speaking ' way of thinking, is it correct to say the dimensions for my Zaskar frame and these cranks will be 68 mm shell and a BB spindle length of 113mm ? I've current got a BB that must have a sindle of 120 mm and it's too long & not giving a good chainline
