I'll be getting some steel sprockets and probably a Tsubaki sigma chain. Don't want to go 1 tooth down on the front, instead I'm thinking about going 2 teeth up on the rear.
The problem is that most places I've checked offer only 42t rear sprockets. I've read the people have 43's even 44's but I can't find any.
Any idea where I could get a 43 tooth rear sprocket?
Cheers
