Just bought a set of 09 sids with post mount, but since my 07 xtr disc were on an old (06)set of IS mount sids I seem to need an 160mm IS to post mount adaptor but can't seem to find one? Why on earth is this?,
I found this http://www.chainreactioncycles.com/M...?ModelID=13744
Shimano adaptor to mount a 51mm international standard caliper to a 74mm post mount fork to accomodate a 170mm disc.
but considering the xtr disc doesn't even seem to come in 170mm it'd be pretty useless.
Anyone care to shed some light on this please? Am I missing something obvious?
