Know before you buy
No, this set is specifically engineered for the Shimano Dura-Ace R9100 rear derailleur. It is not designed to be cross-compatible with other series, such as Ultegra or 105.
You should consider replacing them if the teeth on the pulleys appear sharp or 'hooked' rather than flat-topped, or if you notice increased noise and friction during shifting. If the pulleys have noticeable lateral play or the bearings feel gritty when spun, it is time for a fresh set.
Yes, this is a complete kit that includes both the guide pulley and the tension pulley, ensuring you can refresh your entire derailleur cage at once.
Yes, both pulleys in this set feature sealed bearings. This design helps minimize friction and protects the internal components from road grit and moisture, maintaining smooth performance over time.
You will generally only need a standard 3mm or 4mm hex key to remove the pulley bolts. It is a straightforward process, though you should be careful to note the orientation of the guide and tension pulleys, as they are specific to their positions.
