Ultra-high performance chainring, with superior functionality to any other ovals, specially designed for OX Compact Plus+ crank.

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

"What is Autofocus mechanism?"
When the forth is applied to the pedal, the chain moves outward. You feel the ring increases the diameter as the chain runs higher on the ring. As amount of moving will fluctuate by the force applied, it maximizes the benefits of non-circular ring, and assists your pedal stroke to remain efficient.
*there is no need of pedal stroke analysis to identify peak point or adjustment of mounting position.
*As positional relation with outer ring is fixed, excellent shifting is ensured.
*Special tooth profile prevents chain-drop.

Super Hill Crimb
*Special design, ultralight non-circular chainring perfect for hill climb and long ride.
*Super small 27T available, which gives you gearing 44/27T, lowest in Compact plus+combinations, and helps you to ride up steep slopes.
*Perfect shifting and no chain drop, a chainwatcher is not necessary, which can trim your bike weight.

Material : CNC aluminum alloy
Chain : SHIMANO 11 speed
P.C. D. : 74mm
Size : 27T, 30T (Inner) for “Compact Plus+” system only, use CP110S 44T or 46T outer ring

*Front derailleur needs adjustment.
*We recommend to mount a long cage rear derailleur, for example RD-○○○-GS.
*Some gearing setup numerically exceeds front derailleur capacity.
However, CYCLOID is designed for Shimano 11speed and works perfectly fine with it.
