Ultra-high performance oval inner chainring, CYCLOID SHC and CAPACITY BOOSTER (big pulleys) specially designed to work with SHIMANO 12 Speed drivetrain.
CYCLOIDⅡmechanism
CYCLOIDⅡis the non-circular chainring developed uniquely by Sugino.
“Autofocus mechanism” assists your pedal stroke to remain smooth and efficient at all time so that your pedaling technique can be dramatically improved. Thus, CYCLOIDⅡis the innovative high performance chainring, totally different from any other ovals
Super Hill Climb
*Special design, ultralight non-circular chainring perfect for hill climb and long ride.
*Super small inner chainring 32T or 33T not available from SHIMANO offers great performance gain at hill climb.
*Using #804 bolts will ensure that the overall weight will be kept down.
CAPACITY BOOSTER
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.
Compatibility :
SHIMANO FC-R9200 / RD-R9250 (DURA-ACE)
Chain : SHIMANO 12 speed
CY4-SHC-12S
Size : 32, 34T for SHIMANO 50T / 33, 36T for SHIMANO 52T
P.C. D. : 110mm (SHIMANO 4 Bolts)
Material : CNC aluminum alloy
Color : Black / Gold
CAPACITY BOOSTER-CB12SDA
Guide pulley 12T & Tension pulley 16T
Material : CNC aluminum alloy (S3 coated)
Bearings : Ceramic (sealed)
*Not compatible with RD-R8150 (ULTEGRA) & RD-R7150 & R7100 (105)
*Set includes 1 CY4-SHC-12S inner chainring and 2 Pulleys (guide & tension)
*FC-RS520 which is 12-speed crankset with equivalent features to 105 is not compatible with CY4-SHC-12S.
*Front derailleur needs adjustment.
*50-32T and 52-33T gearing setup exceeds drivetrain capacity and have slack in the chain. Sugino large pulleys perfectly fit Shimano 12-speed drivetrain, work with the standard cage on Shimano derailleur and boost derailleur capacity and shifting performance.
*You can use the original bolts that came with your SHIMANO crank or #804 for SHIMANO (sold separately).
