Stop when you want to.

At the end of last season, you promised yourself you'd finally buy some fresh rotors in the spring, so don't put it off. If you're running 6-bolt disc bakes, grab the Shimano SLX RT66 6-Bolt Rotor and make sure you'll be able to stop consistently on the muddy, rough trail conditions you're bound to encounter in the early part of next season. A steel construction promises durability without a hefty price tag, and strategically carved mud-shedding slots throughout the rotor's body help your pads stay cleaner and less crusty on wet days.

  • 6-bolt disc rotors that keep you stopping with precision
  • Slots throughout body help shed mud and debris
  • Durable steel construction holds up to trail abuse

  • Familiarity: I've put it through the wringer

Although the RT-86 Ice Tech rotor theoretically runs a bit cooler, these rotors do the trick quite nicely at a very reasonable price.

No complaints Here

Great quality rotor at a really great cost. Put these on my partner's mountain bike and she is psyched. If you are entry level to intermediate no need to splurge on rotors.

Does what its supposed to do at low cost

  • Familiarity: I've put it through the wringer

I put these on a new wheel set I ordered that didn't have the center lock. Ordered these and they have been great. Didn't cost too much and have stopped me when needed. I am more of a XC rider so I don't know how they would perform under more DH type application.

Good budget rotor

  • Familiarity: I've put it through the wringer

It's a mid-range product, but it performs flawlessly. It won't ice you, but that's ok. Yes, there are lighter ones, as well as fancier ones, but if you need to stop, this will work.

Nice and cheap

    Great rotor for the money. Not quite as nice as the XT but also not as much $$

    Good So Far

    • Familiarity: I've used it several times

    I switched over from the dark side of SRAM to Shimano and didn't want to drop the $$ for Ice Tech rotors. So far so good, when I heat these rotors up in combination with the resin pads, I get some nasty squealing at the end of the ride when everything is really hot. I am trying to figure out if it's the rotor or the pad. Other than the extreme heating issue (that might be caused by the pads) I have been happy with these rotors.

    Needed some inexpensive rotors to replace on my commuter bike. These rotors work great!
