Hi All,

I am looking at fitting a 205mm disc to the front my 05 RM ETSX. At the mo its got a 185 front rotor and a 160 rear on the bike.
So my thinking is that if I put a 205 on the front and fit the 185 to the rear it will give me better braking!!!.
Now the thing is, what type of mount do I need?
The brakes are Avid juicy 7s with caliper mountings at 74mm centres. Front forks are RS revs, 08’s. Not measured rear sizes yet.
Cheers, STEVE.

is (fork)to post (brake) front 205
is (frame)to post (brake)185 rear
the 185 front will be a 165 if you put it on the back sadly.

Thank you.
