Chain length question?

[gentlemanjim]

I'm buying new sprockets and chain 17x30. How many links chain would be the correct fit 100 or 102 or other?

to fit A? .......normally your stock lenght will work ok and since chain usually comes with extra lenght it's easier to just slide the wheel forward and cut it, you will need 3/4 to 1 1/8 inch free play in the chain with shocks 3/4 with a hard tail

I was thinking if 104 is stock and I delete four teeth on the rear sprocket I should get a 100 link chain

that sounds logical... <scratching head> I'm wondering if it's just that easy.

- if you reduce the sprocket by 4 teeth, thats fine but can you be sure those 4 teeth are going to be within the chain contact area?

- i would be more tempted to remove 2 links, assuming the chain contacts half the sprocket

- however, once the sprocket is in place, lay the old chain and count the overlap

 

[jayel]

no it doesn't work that way, it's the circumference of the sprocket that's different... divided by top and bottom run ... put the chain on the bike and then cut it.. much easier

Exactly - That's why I consulted you.

Thanks very much,
