Ahoy !
I recently ran across an item described as a "cyclo-cross" ring. It is the exact, same thing as on my late 70's 2030 tubing Raleigh (Raleigh badged SR crank with a peened together crank arm & spider) and that I've seen on dozens of modestly priced bikes using that model crank. So, leads me to wondering - why did Raleigh, and I assume other factories, install cyclo-cross rings on bikes that clearly were not intended for cyclo-cross use? I have to admit, that in my green and youthful days, I thought the ring was a futile attempt at a compact chain guard to prevent trouser cuff mangling. For restoration of a "modest" bike from this mid-late 70's period - how common a component, this ring ?
Thanks.
