Here were products.
Those were divided into four groups such as the racing model, the touring and 10-speed model, the BMX chain-wheel, and the BMX stem.
1. The racing model
Aero-Mighty was the highest grade model.
There were AS and GS as inferior models of Aero-Mighty. All of them had streamline arms.
2. The touring model
AT which was PCD 110-74 mm, GT which was a reasonable model of AT, and PX which was often used for mass-production randonneur were put in the lineup.
AT was a forerunner of professional chain-wheel of MTB.
It was equipped with the PCD 74 mm special mount on the back side of the PCD 110 mm 5 arms which was direct descendant of Mighty-Tour.
Therefore it could be equipped with minimum 24T sprocket.
We can say that AT was prototype model of subsequent chain-wheels for BMX of each maker.
PX which had five pins was familiar to veteran cyclist.
A ring of PX was interchangeable with a ring of TA Cyclo-Tourist, and Storonglight 49D.
The form of chain ring was almost same as TA Cyclo-Tourist.
