  • Shimano SLX SM-RT66 Disc Brake Rotor 203mm

The Shimano SM-RT66 disc brake rotor delivers exceptional performance with its 6-bolt mounting system. Specifically designed for Shimano Zee and SLX disc brake systems when paired with 6-bolt, non-center-lock hubs, these brake discs ensure reliable braking.

Featuring a precisely cut and drilled stainless steel braking surface, these rotors enhance pad clearing in muddy conditions and facilitate cooling under heavy loads, thereby improving pad performance and longevity.

These are excellent quality and give great value for money.

Features:

Larger disc brake rotor option provides consistent brake performance with more power. 220 mm disc brake rotor provides 10% more stopping power than 203 mm. Easy to install anti-loosen plates help secure disc brake rotor bolts in place
Resin/Metal pad compatible

 

- Durable Construction: Crafted with Shimano's advanced technology, these rotors are designed to last, ensuring consistent performance and durability against wear and tear.

    Brakes as new again

    My old rotors were contaminated with a bike cleaner of some kind. My own doing too.

    Tried to clean them, boiled them and set fire to them but this is the only way......new rotors.

    SLX Disc brake rotor

    I have had several of these in the past - they are fab. They look great and work really well and are not too expensive. Biketarts price was the most reasonable of all the reputable bikeparts suppliers.

    Service was incredibly fast - delivered on the second morning after placing the order.

    All in all, very pleased with my purchase.

    Good price and does the job

    I have not fitted this one yet as I am waiting for an adapter to come back in stock with Uberbike but I have one on the front already.

    Great stopping power and a great price, delivery was quick.

    Shimano discs - sintered compatible - great price.

    High quality as expected from Shimano. Disc arrived boxed complete with 6 new retaining screws and the 3 retaining tabs. As a note, the screws are have blue thread lock pre applied - a nice detail that save messing around with the usual bottle of loctite.
