You'll have to file a little bit off the hanger - not a big deal.I fitted a couple of washers to centralise the hanger with the disc, it will be obvious when you come to fit it.Altogether a definite upgrade.
do the washers go between the bracket and the caliper then? Do you know size needed and how many?
Please excuse the grubbiness of the bike, it's my winter hack.2 ordinary 10mm flat washers, just try to get the caliper as central with the disc as you can.
