These Pulleys are for ROAD USE only.
Introducing Kogel's "Not For Instagram" Pulleys....The name of these pulleys came from the fact that Instagram videos were limited to 15 seconds. There is no way to show how well they spin in 15 seconds. Since then Instagram has lifted the long video ban and Kogel decided to keep with the name!
These pulleys will fit perfectly on your Shimano Dura-Ace R9000 and Ultegra R6800 derailleurs as an oversize upgrade. The narrow wide tooth profile on the top pulley helps to retain shifting accuracy by pushing every link of the chain. These pulley wheels are built to last with aluminium cogs and serviceable Grade 3 ABEC-5 Full ceramic bearings. (Road seals). This road seal version runs with minimal contact seals to achieve the lowest friction.
Kogel's ceramic derailleur pulleys run on the same trusted ceramic bearings that are used in their bottom brackets. Using aluminium instead of plastics for the wheels makes them durable, especially for off road use
