Thinking of changing my trusty old Mono M4’s to possibly M4 Race front / X2 Race rear

Worth doing or no real difference?

Are the X2’s up to 15 stone bloke duties (mainly cross country but occasionally get to the Alps)?

thanks

I have race x4 front and race x2 rear on my enduro and been fine for everything I’ve tried. But I don’t play on full on dh tracks and I’m a good amount lighter.
One finger locks the front wheel with ease

I’ve got m4s 180,160 I’m heavier than you n they stop mint,now!, however they didn’t used to,so maybe get them bled & set up,change the pad material & keep them,mine are better now than when I got them,no question.

I had a Tech M4 / X2 combo once. If buying again I’d just get X2’s & a big rotor up front.

Not much real difference. Would probably be worth giving them a full service with new seal and fluid, new pads and perhaps new rotors if they are a few years old. The race levers do look prettier though …
