Looking to lighten my Five, so was thinking of replacing the Moto V2s ( with vented discs) with something lighter. Was thinking about X2s but the Hope website I states up to 183mm.
Can I run them with 203mm rotors?
Are the calipers size specific (i.e. 160, 183 etc) as the CRC website doesn't state anything?
Am I likely to feel underpowered after the V2s.

Yes

No; you get different adaptors to use specific rotors with whichever (IS or PM) mounts you have.

Yes.
Tech M4 203mm front with Tech X2 183mm rear will give you a great balance of power/weight.
If you really want to loose weight, also go for Ashima rotors - they work fine with X2's
Thanks.
Not a big fan of 4 pot calipers, hence why I was looking at X2s over M4s.
So which adaptor would I need to use a 203mm front rotor, 74mm post to 74mm post 203mm?
It's Hope mount adaptor C if you have a PM fork.
Any particular aversion to the M4? I've used M4s in one way or another since the original Mono M4; currently using the Tech version front and rear. I've never found them to have any problems that are uniquely related to their number of pistons.
I have some original (pre mono) M4s and they have always suffered from unequal piston travel.
