I am just building up a solaris by ripping everything off the soul. One this I hadn’t thought about is the forks I have bought are post mount. The Hope M4 frontie is am IS mount

Currently I am running a 203 front rotor on the soul and no adapter was needed.

Can I get an Post to IS adapter that doesn’t increase the rotor size by 20 mm.
And I am assuming front and back adapters are specific?

A2z post to is to keep 160

Halfords do um. Winstanleys think they do but they send you an is to post 160. Useless

One of these sounds like it’s what you want?
kcnc mount

the kcnc jobby looks like it could work!
thanks

Unless your forks are reba’s (or possibly other rockshox maybe?)

they are revelations

arse – doesn”t work!!
Fits onto the fork – but the brake sits too fat inboard and it fouls the spokes!!

Any other suggestions?

I had trouble with that very combo, only I think i remember the brake calliper fouled the adapter. I don’t think I got far enough to worry about it fouling the spokes! I was trying to fit a is180 M4 rear on a Turner triangle, so would have though it would have been equivalent to what you’re attempting.

So sorry, can’t help!
