Shimano Pulley Set (Jockey Wheels)

Surgical Shifting. Silent Engagement.

The Shimano Universal Pulley Set includes a precision-engineered Guide Pulley (top) and Tension Pulley (bottom). Designed with Shimano’s proprietary tooth profiles, the Guide Pulley features a specific amount of "lateral float" to compensate for minor cable stretch and indexing imperfections, ensuring your chain finds the target cog every single time.

Why a Fresh Pulley Set is a Maintenance "Must":

• Restored Shifting Snap: Worn pulleys develop "pointed" teeth and lateral play, leading to hesitant or "ghost" shifting. A fresh set provides the sharp engagement needed for instantaneous gear changes.

• Whisper-Quiet Drivetrain: As pulley bearings wear, they develop a distinct "grinding" or "chirping" sound. These pulleys feature high-quality internal bushings and seals for a silent, smooth-rolling experience.

• Super-Fluid Drive™ Geometry: Specifically designed to work with Shimano chains, featuring chamfered edges that reduce friction and chain wear.

• Industrial Strength Composite: Forged from a high-density, low-friction composite material that is far kinder to your chain than aftermarket metal pulleys, significantly extending the life of your entire drivetrain.

• Centeron G-Pulley Technology: The upper guide pulley utilizes Shimano's Centeron design to allow for subtle self-alignment, making your derailleur more "forgiving" and easier to index.

• Massive Compatibility: This kit fits a huge range of Shimano derailleurs across the families, making it the perfect "emergency spare" for any toolbox.

Technical Specifications:

• Tooth Count: 11T / 11T

• Quantity: Sold as a pair (1 Guide, 1 Tension)

• Bearing Type: High-Precision Bushing / Shielded

The Alegro Perspective: In the shop, we call the pulley set the "hidden tune-up." If your chain is new and your derailleur is straight, but your shifting still feels "vague," it’s almost always the pulleys. Most riders wait until the teeth look like "shark fins" to replace them, but swapping them once a season will keep your drivetrain feeling elite and prevent premature chain wear. It’s the cheapest way to buy back that premium Shimano feel.
