The legendary Sugino 75 model pro track racing chainring, in either, the original, classic Silver anodized finish or the Satin anodized Black finish.
The Sugino 75 chainring is 144 pcd size, so you will need a crank set like the Sugino 75 and Grand Mighty models, or Shimano Dura Ace models. Generally, any pro-racing quality track crankset will be 144 size.
Most cheaper, 'street' cranks will be 130 pcd.
The Silver Sugino 75 model is approved for use in pro keirin racing in japan, and therefore features the NJS stamp of approval.
It is one of the most popular pro racing chainrings of all time, and is still being used by pro riders in Japan and worldwide...perfect for street applications too!
This chainring is designed to be used with a standard track 1/8" size chain.
