I have a Scandal and when trying to fit a rear XT brake I seem to have a problem with the rotor size. I thought that the brakes worked with a 160mm rotor but it looks like only a 140 will work. So do I have:
A. Have the rotor size wrong and they do use 140mm
or
B. The swapouts need a +20 IS>PM adaptor
or
C. None of the above?
I can see how I can fix it with either a new rotor or adaptor but I was wondering where I went wrong.
Anyone had any problems?
assuming the swap out is the same as on my C456 then a normal rear 160mm adapter should work fine.
Are you sure the adapter is the correct one - ie an R160 and not an F160 (front) and it's fitted the right way round?
My C456 is running XT 785 brakes and 180 rear disc with only the standard Shimano 180mm adaptor needed.
26er or 29er Scandal and internal or external brake mount?
Ooooops double post.
Thanks for the replies folks, I've worked out I seem to have 3 front adaptors and no rears, this was compounded by the fact I was also trying to fit a calliper to a Pugsley front anaw. I think I'm sorted now though.
front 180mm adapter is normally the same as a rear 160mm adapter except for shimano as the holes are not quite in the same place in the axis of the wheel axle (can't remember if the front or the back adapter sets the caliper slightly more inwards)
