Weekend Links: App for air pressure, new book from former NYDOT commish, and a tack attack on PCH

Mike Wilkinson sends word that you’re probably riding on the wrong tire pressure.

A lot of people do not have the right tire pressures on their bike. If your bicycle tire pressure is too low, your bike will handle poorly, you’re more likely to get a flat, and it will be harder to pedal. If it’s too high, the ride will be rough without really improving efficiency. What’s the sweet spot?

In 2007 Bicycle Quarterly published an article that recommended setting the pressure so the tire would compress 15% when loaded. That’s hard to measure, but never fear… an app is here!

The app (sorry, Android only) is available from Amazon and Google Play. The cost is $2.50. It has some handy preconfigured options and a custom option.

Entering the numbers for my go-fast road bike, I was surprised at how much the app wanted me to lower my tire pressure. I was happy to see that I had the recommended pressure in the front tire of our tandem, but the app said I should put a lot more air in the rear tire.

It’s great fun for bike geeks like me, and it might give you a better ride for less effort!


Looking forward to reading this new book by former New York DOT Commissioner Samuel I. Schwartz, head of Sam Schwartz Transportation Consultants and the man credited with coining the term gridlock.

So far, I’ve only made it through the prologue and first chapter as I rode home on the subway the other night, and already learned more than I knew before about how we got into this auto-centric mess we’re in, and how we can get out of it.



Streetsblog’s Joe Linton recaps Thursday’s meeting of the Planning Commission, which voted unanimously to keep Westwood Blvd and Central Ave in the LA Mobility Plan.

Wrong though he may be, at least Paul Koretz had the guts to show up in person to argue against the bike lanes on Westwood; fellow Councilmembers Curren Price and Gil Cedillo sent their staff to do their dirty work.

And the Wave newspaper reports on the protest against Price’s attempts to kill the bike lanes on Central Ave.
