A new pulley for Shimano 12-speed is here!
Simply replace the original pulley to increase the capacity of the rear derailleur, solving the chain slack issue when using CY4-SHC 32T and 33T.
FEATURES
Swinging Eccentric Mechanism
The guide pulley swings in response to the movement of the rear derailleur due to the eccentricity of the mounting shaft, automatically adjusting the gap with the sprocket to achieve shifting performance equivalent to the original pulley.
Rotation Resistance
The enlargement of the pulley and the use of ceramic bearings reduce rotational resistance.
Friction Resistance (S3 Coating)
A special surface treatment that combines an extremely low coefficient of friction with high hardness. The friction resistance is less than half that of titanium coating, minimizing chain resistance.
SPECIFICATION
Bearings: Ceramic
Teeth Count: Guide Pulley 12T / Tension Pulley 16T
Compatibility:
Shimano 12-speed
FC-R9250 (DURA-ACE)
