Sorry Chuck,

I don't have the chainring you're after.

I just wanted to mention that 51 was the preferred chainring for roller racing. 51 x 14 with an average tire will nail the 303" roll-out restriction.

I suspect that in inch pitch days the biggest gear that guys would have was a 25 x 7 and the tires were fatter then, so it rolled out to 303". Any other theories where the 303" came from?
