KOGEL BEARINGS rear derailleur pulleys 2nd generation 12-14 teeth | Full Ceramic | Shimano Dura Ace R9200 | black / blue
These oversize derailleur pulleys are specially designed for the current Shimano Dura Ace R9200 road bike rear derailleurs. The original rear derailleur cage can be retained when using the Kogel 12/14 oversize pulleys. The upper pulley has a narrow/wide tooth profile for better chain guidance. This ensures optimum shifting performance despite the larger pulleys.
2nd generation
Kogel's second generation derailleur pulleys are dimensioned so that they fit into the standard derailleur cages from SRAM and Shimano and the highest possible number of teeth is utilized. The pulleys themselves are milled from aluminum and have a tapered edge on the teeth to prevent the chain from jamming when it starts dancing on jumps and rough descents. In addition, the height of the teeth has been increased to ensure better chain retention.
What remains unchanged are Kogel's super-smooth ceramic bearings and the choice of seals.
Full Ceramic Bearings
For the best performance, full ceramic bearings offer the lowest possible friction and are designed for use in the toughest conditions. They offer unparalleled smoothness and durability.
Road Seals
A minimal contact seal designed for the smoothest possible running.
