If your GRX derailleur is getting noisy or not shifting smoothly anymore, these genuine Shimano pulleys will get it running like new. This is the exact same quality you get from factory Shimano components - no cheap knockoffs here.
The set includes both the tension and guide pulleys, so you're replacing the whole moving assembly. The bearings are buttery smooth and the tooth profile is optimized for GRX's specific chain requirements. Installation is straightforward if you're comfortable working on drivetrains.
What I really appreciate is that these are official Shimano parts - the fit is perfect and the durability is exactly what you'd expect from a premium brand. No weird compatibility issues or questionable manufacturing like some aftermarket options.
Perfect for when your original pulleys are worn, damaged, or just need an upgrade. Your shifting will be crisper, quieter, and more reliable. If you're maintaining a GRX groupset, having these on hand saves you from downtime when pulleys eventually wear out.
