am upgrading my 3 yr old XT 160mm front rotor to 180mm. The 160’s are centrelock ‘RT 77’ and I am going to order 180mm centrelock ‘ XT M770’ replacement (along with the adapotor)

can anyone confirm compatability ? cheers

I have a 180mm centrelock rotor I was going to stick on ebay if you’re interested for £11 posted.

No adaptor though I’m afraid. I know it goes OK with ’07 XT brakes as that’s what I ran it with.

chapa, I have the front one in a wiggle basket for about the same amount after discount. could be tempted to change the back too though……

what condition is your’s in ?

Just checked.

RT78M, dead straight, no scoring. Not had a great deal of use as I switched to different wheels.

chakaping – yes please, just mailed you. cheers

RT77 / RT78 / RT79 are all interchangable. A long as it is still 180mm then you can use pretty much anything.

great, front sorted, just need a post mount to post mount 180mm rear adaptor now….
