• Belt drives are very picky for chainline or "beltline" I suppose. Gates told me 1.5mm or less front to rear or it risks hopping off.

    Good progress all round. Fair enough with the London hassle, just thought maybe I'd meet the man, the myth, the legend in person

  • Yeah, strangely I think the Ultegras ended up having a better belt line than the stock cranks, only by 0.5mm or so but still.

    I did buy some alfine cranks off here but the belt line with them was going to be miles off. I’ve found pictures online of alfine cranks with the pulley mounted in both inner and outer positions so who knows how that works! The rear pulley is also offset but it can only go one way around I’m sure.
