Revolutionary pulley wheel set from AbsoluteBlack, built in a completely different way than seen before.
The pulley wheels reduce noise by up to 12 db compared to standard pulley wheels from SRAM.
The upper pulley wheel has 12 teeth and the lower one has 18 teeth, which reduces friction on the chain compared to the standard 11 tooth pulley wheel. In addition, the pulley wheels are made with higher teeth for more precise gear shifting.
Bottom pulley wheel is where the revolution starts. It is built up with a greater rotation on the ceramic bearings, which means that the rolling resistance is lower than before.
The arm itself is made less rigid so that it flexes a bit. This also gives more cash change, contrary to what many people think.
Fits Shimano Ultegra and Dura-Ace R8000/R8050 and R9100/9150 series.
Comes complete and assembled, ready to put on the rear derailleur.
Two extra spacers are included in the set
