Looking at purchasing new brake rotors to go with existing XT calipers. Need a pair of 6-bolt 180mm. Is there any point in not sticking with Shimano (possibly RT66)? I’d be tempted to try Uberbike if there was another sale on. Does anyone have a specific rotor to recommend? Mostly for XC / trail riding, not gnarcore DH.

One benefit of sticking to Shimano is that you know it’ll be the right size.

Other makes of this mid-sized rotor can in fact be 183mm and 185mm, although it should be obvious when buying. A 185mm rotor might hit in the inside of your calipers.

Shimano are only ever 180mm, so you can’t go wrong.

Just stick with non-spider SLZ/ZEE (RT66).

I got a pair of those RT66 rotors in the sales after Christmas. Made the Deore brakes on my single speeder loads better then whatever after market shonk was on there.

Thanks for the tips, I think I’ll opt for the rt66 then.

I’ve got xt ice thingies and the braking is ace, they also look ace

I’ve just got some Uberbike ones, really like them so far. They had a 17% off code on their Facebook page recently.
