If your thinking about getting into track racing get on this. Cheap as your ever going to find and you’ll never have to buy another cog/chainring again.
I saw that and was tempted but I know I’d end up hunting a full Superbe track group around it and that would be costly!
How many do you need though? I think I only used a 14 and 15T sprocket and 49 and 50T chainring. That’s me though… 17T NJS sprocket is unusual isn’t it?
i think its common, may now be harder to find tho…i had a nos 17 teeth NJS one
i’ve used everything from a 13t to a 16t, and from a 47t to a 51t. having that range rules.
But you’re a professional Brendan.
I started with a 50t and 14, 15,16, that gets you 84", 90" and 96" add a 49 & 51 and you can fill in the gaps. Some trackies obsess and will change both chain and cog just to get an extra 1/2" but until you know better go with something straightforward. Most times you aren’t fit enough and that is why you didn’t win…
he wasnt always…
