Best gearing ratio

Ok....so far I’m seeing that a 15/35 would be better for off the line. I’m using a 530 chain along with my 16” wheel which I verified. Just wanted to confirm before I commit.

15 / 35 is based on 630 chain 1/ 2.33 I think

just do the math for the ratio and convert to whatever is the equivalent ratio in 530 chain sprocket sizes

Thanks StreetFighter.

Can someone please state the advantage of converting to 530 setup.

Weight and maybe cost?

Is it a rotating mass thing. The lighter something is the fast you can get it spinning

Lighter and less rotating mass

Found this in a post from 2007;


530 X-Ring chain and 630 O-Ring chain are virtually the same width - they both use 3/8 wide rollers (that's the 30 in the 530 and 630 - that means 3/8" width for the rollers).

Spacing isn't an issue provided you install a spacer washer on the front sprocket.

The benefits for 530 over 630 are considerable - cheaper, better selection, better wearing, and lighter. The cons - really none - except for a couple of bikes where there isn't a readily available 530 rear sprocket (KZ900 LTD uses a unique rear sprocket - so no 530 rears are readily avialable).
