• Ok so I’m looking to try out some longer cranks, and fancy going from 172.5 to 180mm. The frame I’m thinking on running them on however, has tight crank arm clearance even with 172.5mm 5800 cranks, and had to have the chainstay dimpled to get to fit.

    Only sram really do cheaper 180 Mm cranks and ive found the dimensions clearance wise for these, but does anybody know where I can find the dimensions for hollow tech cranks?

    Equally if this doesn’t work what would be my options for getting more clearance to the chainstay apart from another “tactical dent”? Can I space out a gxp or hollowtech bb?
