Overview
What does the Dura-Ace Di2 RD-R9250 pulley set bring back to your drivetrain?
If your Dura-Ace Di2 12-speed rear derailleur has racked up serious miles, this pulley set is the simplest way to restore that brand-new, friction-free feel. The kit includes both the guide pulley and the tension pulley designed specifically for the RD-R9250, each running on precision sealed bearings with dust covers that keep contamination out and pedaling efficiency up. Worn pulleys are one of the most overlooked sources of drivetrain drag, and swapping in fresh ones makes a noticeable difference the first time you spin the cranks.
Built to the same exacting standard as the rest of the Dura-Ace R9200 series, these are the genuine Shimano replacements, not aftermarket lookalikes. Installation is straightforward for any home mechanic comfortable with a derailleur, and once they're in, your shifting goes back to that crisp, silent Di2 character it had on day one. If you're refreshing a race bike for the season or just keeping a high-end build running like new, this is the right set.

Good questions
Get to know Shimano
There's more to Shimano than this one product. Our Shimano page has the full Shimano lineup we carry and more about the brand.
Visit the Shimano page →Which derailleur does this pulley set fit?
The RD-R9250 Dura-Ace Di2 12-speed rear derailleur. Other derailleurs, including Ultegra, use their own pulley sets.
What is included?
Both pulleys: the guide pulley and the tension pulley, each 11 teeth with sealed bearings and dust covers.
When should I replace my pulleys?
When the teeth look hooked or worn down, or the pulleys feel gritty or loose when you spin them by hand. Worn pulleys add drag and can make shifting less crisp.
