[Closed] Can I mount a V2 rotor in an M4 caliper?

I think the rotor may be too wide.

If its vented no but the conventional ones should.

If the V2 rotor is a vented one then it will be too wide - they are about 2.90mm
The un-vented (i.e. floating) V2 rotors were slightly thicker than a normal rotor which is 1.50mm for >180 by about 0.40mm from memory ...

You *might* be able to squeeze a floating V2 rotor into an M4 caliper but I would envisage a tight squeeze especially with new pads fitted.

Either way a quick email to Hope Tech themselves will provide you with a definitive answer!

Don't forget to consider the depth of the rotor. It isn't going to spoil the function, but half the braking track will be hanging out the bottom of the caliper.

I’ve got 203mm V2 floating rotors with Tech X2 calipers. No issues at all.

Loads of extra stopping power in the tight, twisty, tech stuff, where it’s almost trials riding.

There’s no difference with rotor coverage compared to the 180mm floating rotors that were on before.

A day at Lenzerheide says they work fine.
Thanks for your answers, STW.
