Why We Like The Shimano XT SM-RT86 Rotor

Shimano’s XT Brake Rotor, the SM-RT86, sets itself apart from Shimano’s lower-tier offerings through its use of an aluminum core to transfer heat away from the brake caliper. This, combined with the finned heat sinks in Shimano’s XT and XTR-level brake pads, combats heat-related brake fade. We appreciate this construction because it translates to consistent, reliable braking even on long descents.

Awesome Rotors

I've put it through the wringer

5' 9"

Couldn't be happier with these -- Shimano makes a great product. Running these now on both my bikes (a hardtail XC and a full suspension). Great linear feel, quiet, and all the stopping power needed. I've been riding on these year-round for about 18 months now and they have worked flawlessly rain or shine. Most all of my riding is on beginner & intermediate single track with steep but short hills, although I did spend a full day last summer doing nothing but harrowing downhill runs at a bike park (fun btw!). That gave the brakes a good workout....no issues.

I have a 203 up front and 180 in back paired with a set of M9120 brakes and I have no complaints.
