I'm looking at changing to a pair of reba's some pretty good deals out there but on Post mount. I have IS mount callipers running 180mm rotors and i don't really want to do 203mm.
So can i get a adapter that will keep the rotor size at 180mm?
Cheers
Paul
Sure?
"Shimano mount adaptor to mount a 74mm post mount caliper to a 51mm IS mount fork with a 180mm rotor. "
I'm looking at a post mount fork with a IS caliper.
Or is running the other way round its party trick?
Doh, read it the worng way round, pretty sure shimano do one but there loads of options on CRC site:

I don't think you can TBH speshpaul, I was in the same position as you, IS XTR callipers and a direct post mount Magura fork, couldn't find one that would do the job, had to get new callipers eventually
Shimano don't do one to do this job.
After looking in a bit more detail and not shooting posts off quickly it appears you may have to go up to a 203 on the front, sorry, be cheaper than getting new calipers anyway !!
Just out of interest, what calipers?
Mono Mini.
Would this not do it then ?

It says you need a 20mm larger disc, so if a standard post mount fits 160mm this should fit a 180mm, or am i missing something ?
tragic - hope IS mount calipers come in different varieties for different size discs - so if you have the calliper for a 180 disc using is mount forks you have to go to a 203 disc with the adaptor for post mount
😳
OK thats me told, i will shut up now !!
Try going to www.a2zcomponents.com they specialise in doing adapters of this sort. Many of the adapters that they offer are compromises but will work.
