I spotted a chainset on the internet i would like to buy. The shop says when used with a 110mm square bottom bracket the chainline is 43.5mm which i think is a road chainline. I have a mtb groupset so can i just add the 6.5mm by increasing the bottom bracket spindle length by 13mm? I would have to buy a 122.5mm bb thats only 0.25mm off.
Would this work? The chainrings included are the right size and difference for a mtb front derailleur.
