The perfect answer to a 2x road style derailleur that can be used for both gravel and road rides. The new clutch based system puts you in control of both worlds. Tighten it up when youre going off road to ensure the chain is tensioned across the rough stuff. Then loosen it off when you plan to head on out to the smooth terrain for efficient pedalling.
The added weight of the clutch compared to road variants only makes the RD-RX800 40 grams heavier and makes you a beast on and off the road.
