i just received my 15 tooth sprocket and while installing it i noticed it was narrower than the stock one, it did fit the chain perfectly, just narrower, is this normal?
Stock is the 530 chain. Not being too well versed I'm guessing you might've gotten a sprocket for a 520 chain. 520's are narrower, lighter than the 530's.
Yeah that's the same thing they did to me, when I ordered my 15 tooth. They sent me the jt sprocket in the 520 not the 530. They told me to keep the 520 and they would send me a new 530 worked out pretty good.
I'd probably get on to them for a replacement before you ride it around too much. It might feel fine but wouldn't all that extra play in there cause it to slap around and wear prematurely?
Thanks for posting! I'll be sure to check if I ever have to replace mine.
