Hey I used to ride with you guys about a year ago and have been moving around a bunch since then(I actually ran into aron in sacramento not too long ago). anyhow i remember someone moving down to san francisco and starting a similar group there and since i will be moving to sf shortly i was wondering if anyone knows what the website for that group is.

also there was a chart in these forums a while ago of gear inches and skid patches, anyone have that still?

you're thinking of Kori. She's since moved to Portland for school. There are no shortage of hipster kids on bikes in San Fran, finding a regular ride might be a challenge though.

gear inches: the number of inches you move forward with one revolution of your crank.

# chainring teeth /# cog teeth * 27(diameter of tire) = gear inches

skid patch: the number of different holes you'll wear into your tire given a specific gear ratio and the fact that you always skid with your cranks in the same direction. the higher the better.
think of it as the lowest common multiple of your chainring and cog.
