Hi can i use after market rotors with giants own hydraulic brakes or have i got to get giants own rotors to use with these, would prefer to go to 180mm F&R…cheers dai

Shimano centrelock rotors works fine with the MPH brakes on my wife's bike.

Give it a go.

should be fine, just try and match the track width (area the pad contacts)

u using the new mph roots?
or old mph C2s?

they are the old C2's, will have a look for some on here instead of buying new to start with.

chakaping do you know if a 203mm shimano centrelock will fit on the front??
