These Kogel pulleys are designed for the SRAM Eagle 12 speed 1x mountain bike derailleurs and have a narrow-wide tooth profile for better chain retention. Cross seals only. The specific upper 12 & lower 14 tooth pulley wheels are built to last with aluminium cogs and serviceable Grade 3 ABEC-5 Hybrid ceramic bearings. This cross seal version is built for off-road. Cross seal versions offer the best durability, regardless of the weather conditions.
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.
