The 19 Tooth Foundation

Spin Smarter, NOT Harder!

Our Mission

The 19 Tooth Foundation uses default website templates to bring shorter gear ratios to the fixed gear riders of San Francisco. Our mission is to help others to enjoy their urban fixed gears by spinning smarter, not harder.

Comfort

47:19 is objectively the best ratio for the San Francisco area. One could vary the chainring a bit.

Speed

Did you know: Many riders are faster with a shorter ratio!**


Tires

With 19 or 38 skid patches, you can take off those Thick Slicks and shred like you've got tire money!


Dedication

Many become so dedicated to the 19t cause that nothing else will do!


Knees

People ride street with track ratios then say "I liked fixed gear but my knees couldn't take it" - but did they ever try a 19t? No.*


Don't Call Us; We'll Call You!

We don't want to spend a lot of money on this tbqh. We've already done so much for the world.
