Of all the ways to respond to my (ineffectual) little joke, you chose aggression.
Any saddle sores that need lancing?

The Langster should be a standard track BCD of 144

Bolts don't come with the ring so if you don't have any you'll need single speed bolts not for doubles.

Token chainring - no problems. We have a Token chainset here and it's been.....well, it's just done it's job, which is pretty much all you can say about it.

Token chainring is probably 144. The Langster will probably be either 144 or 130 as both are fairly common on the track - the spec online might tell you. There is also a way of measuring distance between bolts, but I can't remember the formula. Probably online somewhere.

Bolts will not come with chainring - you will need to use the existing bolts on the chainset.

Steel is a good material in the industry. Such as 4140 steel, m2 steel and etc.

How does this affect choice of material for a track sprocket? Which industry? Are you just advertising
