CAPACITY BOOSTER (big pulleys) "ZERO FRICTION" version specially designed to work with SHIMANO 12 Speed drivetrain. Non-metallic full ceramic bearing lubricated with a special dry lubricant has successfully reduced the friction to practically zero.
Just swapping out Shimano original pulleys to Sugino "CAPACITY BOOSTER" increases rear derailleur capacity and prevents chain slack when crosschained in small /small when CY4-SHC 33T or 32T is used*.
*For 34T and 36T, either Shimano original pulley or CAPACITY BOOSTER can be used.
*For 32T and 33T, the use of CAPACITY BOOSTER is required.
"CAPACITY BOOSTER" perfectly fits Shimano 12-speed drivetrain, works with the standard cage on Shimano derailleur and boosts derailleur capacity and shifting performance.
①Swing Eccentric MechanismAs 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 "ZERO FRICTION"Non-metallic full ceramic bearing lubricated with a special dry lubricant has reduced the friction to practically zero.
③Friction resistance (S3 coating)S3 combines high hardness with super low friction coefficient which is less than half that of the titanium coating. So, the chain resistance could be reduced to minimum.
Compatibility:
ZF12SDA : SHIMANO RD-R9250 (DURA-ACE)
ZF12SUL/105 : SHIMANO RD-R8150 (ULTEGRA), RD-R7150 / RD-R7100 (105)
Chain : SHIMANO 12 speed
*Please select ZF12SDA or ZF12SUL/105 depending on your rear derailleur. These 2 versions are not interchangeable.
Guide pulley 12T / Tension pulley 16T
Material : CNC aluminum alloy
Finish : S3 Coating
Bearing : Full Ceramic (sealed)
*Set includes 2 pulleys (guide & tension)
*Use only“neutral” cleaning agents for Super Series (S3 finish). Liquids and others which contain acid or alkali will harm finished surface and can cause malfunction to the product.
*For maintenance, clean it with parts cleaner or in an ultrasonic cleaner and dry it completely.
*Don't use a wet type lubricant for ZERO FRICTION, as it will increase the friction and collect dirt and dust. Use only a dry PTFE lubricant spray when the lubrication is necessary
