THE BEST of both worlds
SRAM DD3-30 is a unique shifting system that combines a three-speed gear hub with a traditional cassette body controlled by a derailleur. It gives you all the gearing you need, but simplifies the system by putting all the controls in one hand. This means a bike that's easier to use, and lets you focus on what you love most: riding.
The gear hub can be shifted at any time, even under load or standing still. The cassette provides a wide range of gears for maximum versatility. It's built for the rider who needs lots of gearing options for touring or hilly terrain.

1:1 Actuation is superior by design. Every unit of cable you pull moves the derailleur the same amount. Actuation stays precise and fluid slogging through mud, bouncing off rocks, rutting through roots wherever you find yourself, whatever conditions you're in. It's dependable. Tolerant. Easiest to set up. Easiest to adjust.
- Clickbox Technology™
Low shifting forces through special outside clickbox.
- ESP Technology™
SRAM’s ESP technology refers to the 1:1 actuation of the shifter, meaning the shifter pulls one inch of cable for every inch of movement in the rear derailleur. Other systems have a 1:2 actuation ratio. The 1:1 system effectively reduces cable tension in half, which means easier shifting with less effort.
- Hybrid Drive™
Combination of 3-speed Internal gear hub and external drive train.
