Replacement sprockets

[GeorgeT]

Time to change the sprockets on my track bike (I will replace the chain too). Sprockets question: steel or aluminum/alloy? Brand preference?

 

[Hooli]

Steel front and rear. The weight savings aluminum rear sprockets make on the street is insignificant.

Thanks. Chain? (O-ring or not)

 

[Hooli]

O (or X)-ring.

Steel on the sprockets.
