Precise control with the SM RT66 disc
The SM RT66 brake disc delivers consistent braking power and plenty of confidence on trails, tours, and in everyday use. Robustly constructed from stainless steel and optimized for modern disc brakes, it lets you get the most out of your bike.
Consistent power in any weather
With the SM RT66, you're getting a durable 6-bolt disc brake for your bike. It delivers consistent braking performance, even in wet, steep, or technical conditions. The one-piece construction ensures stiffness and a direct response, allowing you to fully concentrate on your line.
Perfect for sporting activities
Whether on a mountain bike, trekking bike, or e-bike, the SM RT66 is approved for both organic and sintered brake pads, making it extremely versatile. The large contact area ensures good heat resistance and stability, so your braking performance remains predictable even on long descents.
Quickly assembled. Securely fixed.
Thanks to the 6-hole mounting system and included locking plates, you can install the disc quickly and reliably. The self-locking plates prevent the screws from loosening, ensuring everything stays in place, mile after mile.
