gear booster CAPACITY BOOSTER 11 SPEED – SUGINO STORE

gear booster CAPACITY BOOSTER 11 SPEED – SUGINO STORECAPACITY BOOSTER (Big Pulley Set) specially designed to work with SHIMANO 11 SPEED drivetrain. Just swapping out Shimano original pulleys to CAPACITY BOOSTER increases rear derailleur capacity. *For CY4 SHC 32T and 33T, the use of either Shimano GS rear derailleur or CAPACITY BOOSTER is recommended. For OX2 901D 11Speed, "CAPACITY BOOSTER" can be used with Shimano rear derailleur either SS cage or GS cage *For inner ring CY5 SHC 27T, use a GS cage.

CAPACITY BOOSTER (Big Pulley Set) specially designed to work with SHIMANO 11-SPEED drivetrain.

Just swapping out Shimano original pulleys to CAPACITY BOOSTER increases rear derailleur capacity.
*For CY4-SHC 32T and 33T, the use of either Shimano GS rear derailleur or CAPACITY BOOSTER is recommended.

For OX2-901D 11Speed, "CAPACITY BOOSTER" can be used with Shimano rear derailleur either SS cage or GS cage
*For inner ring CY5-SHC 27T, use a GS cage.

Easy implementation
☑ No need to change the cage on Shimano derailleur!
☑ Even SS (short cage) can increase the capacity!
☑ No need to change chain length!
The capacity can be increased without the need of a special cage nor a GS (long cage). Also, there’s no need to add links to the chain. Thus, you can cut down on unnecessary spending and time. *Please determine the correct chain length according to Shimano instructions.
①Swing Eccentric Mechanism
As the axle is fixed eccentrically, the pulley resonates with the motion of the rear derailleur and adjusts its position to cassette cogs automatically. So, shifting is just as accurate as it is with the original pulley.
②Rotational resistance
The bigger pulleys require less rotation and won’t bend the chain as much. So, the chain can run with less friction. Thus, the ceramic bearing can fully exhibit its performance.
③Friction resistance (S3 coating)
S3 combines high hardness with super low friction coefficient which is less than half that of the titanium coating.　It realizes super smooth disengagement with the chain and suppresses general noises occurring due to the running of the chain on metal pulleys

Size : Guide pulley 12T & Tension pulley 14T
Material : CNC aluminum alloy (S3 coated)
