Possible to get bigger spurs?

You know you're exactly right. I ran through the numbers again on the speed calc and they came out fine. Somehow I must have screwed something up before, not sure where I went wrong though.

I looked on the Caster site but their web-store seems to be pretty incomplete right now. I'll have to give them a call and see about the 10/43, but I think the 13/43 will work fine.
