Thanks honourablegeorge, that’s good to know re boost chainline being sufficient.
Have I misunderstood the chainline calcs then?
I thought that as the FF is +6mm towards driveside at the rear, so a boost front (an extra 3mm outboard) would theoretically still be 3mm too far inboard, whereas a PF30 ring (which is 0mm offset, where a “normal” chainset is -6mm) sound like it should be correct.
Will look at boost chainset options now. That might swing it in favour of the FF, as I had thought I’d be pretty much restricted to XX1 or X01.
Not worried about the re-dishing at all. The more even spoke tension L/R is probably a very good thing. Will also give better mud clearance between chain and rear tyre, something that I’ve suffered from on other bikes in the depths of Winter. I’d be running 29er.
