Oversized Performance

Looking to upgrade or replace worn-out pulleys? Stock pulleys on most derailleurs are made of plastic, which makes them susceptible to flex and premature wear. Upgrading to Kogel oversized ceramic pulleys will reduce drive train friction, improve shifting accuracy and save you from making trips to the shop to replace worn out pulleys.

Here's what makes these pulleys awesome:

• Larger pulleys reduce chain deflection... a fancy way of saying "lower friction"
• Larger pulleys mean slower rotating bearings. (yet another way of saying "lower friction")
• Bomb-Proof stiffness for snappy shifting
• 7075 Aluminum for longer life than stock plastic pulleys

Plus, Kogel Derailleur Pulleys are:

• Easy to install on your existing derailleur cage
• Made with high-quality materials designed to resist wear
• Covered by their two year, Guaranteed Performance Warranty on the bearings

Features:

• Standard "cross" seals for optimal balance of durability and ceramic efficiency
• Optional "road" seals for even better efficiency
• Full ceramic 'Not For Instagram' bearings for the ultimate low friction free spinning experience.
• Oversized pulleys with the highest tooth count that will fit on your stock cage, because size matters.
• Easy installation, simply replace the stock pulleys on your derailleur.
• Serviceable bearings and seal kits so you can keep your drive train running smoothly
• Top-tier grade 3 ceramic balls for the best ball quality you can get (Ball grade rates the roundness of the ball)
• ABEC 5 bearing tolerance for the best support in a cycling application
• Hardened steel races that won't deform over time
• 2-year Guaranteed Performance Warranty on the bearings, so you can feel confident and secure about your next two seasons of riding
