No, 31 is correct. I am going to a 13 front 31 rear. I had to order the 31 tooth rear sprocket from the UK.
If I were sticking to a 428 chain, then the 41 tooth would indeed be correct. I think it may be confusing because I used a 39 tooth sprocket to test out gearing combinations with my current 428 chain setup so I could decide what sprocket I wanted to order for the 520 chain setup. Since the sprockets for a 520 chain are larger in diameter for their given teeth counts due to the 520 chain pitch being 5/8", they use fewer teeth.
That in itself is probably confusing because why not just order the 31 tooth sprocket? Suffice it to say that I could order the 39 tooth rear sprocket for the 428 chain off of Amazon using gift card cash earned for free as a work perk. The 31 tooth I was considering buying required my own money lol. I was contemplating going taller than even the 17/43 on a stock tire, so I was trying to decide between a 30 or 31 tooth rear sprocket. Hence the 39 tooth experiment.
EDIT: Random update. I was going to wait to order the chain, but I came across a DID 520 VX2 X-ring chain with master link for $62 with free shipping. That's 15 bucks less than I paid for my EK O ring chain. Normally this chain would be around $100...The catch is, it's 120 links... Guess I don't have to worry about it being too short lol.
