KOGEL BEARINGS derailleur pulleys 2nd generation Road Seals | 12/14 Z for Shimano Road

The 12 and 14 tooth counting pulley wheels from Kogel Bearings and make your Shimano Road drive more efficient. Due to the large outer diameter of the pulley wheels, the chain itself moves less, it turns more slowly and there is less friction. In short, the bigger rolls make you faster. To further reduce friction, Kogel relies on its tried and tested ceramic bearings. These ensure that the rolls run smoothly and have a long shelf life. The rollers are made of aluminum in order to achieve the lowest possible wear.
The original derailleur cage can be retained when using the Kogel rollers. (L - lower = lower roller, U - upper = upper roller)

2nd generation
Kogel's second generation derailleur rollers are dimensioned in such a way that they fit into the standard derailleur cages from SRAM and Shimano and the maximum number of teeth is used. The rollers themselves are milled from aluminum and have a tapered edge on the teeth to prevent the chain from jamming when it starts dancing during jumps and rough descents. In addition, the height of the teeth has been increased to ensure a better hold of the chain.
What remains unchanged are Kogel's super pliable ceramic bearings and the choice of seals.

Road Seals
A minimal contact seal, which ensures the smoothest possible run.
