Ask Dr. Wally

I simply couldn't resist posting this from CycleDog. Check it out!

Dear Dr. Wally

My auto mechanic filled my tires with 100% nitrogen, claiming that the tires lose pressure more slowly and that gives better mileage. Should I do the same with my bicycle tires?

Dear Curious

Do not fill your tires with nitrogen! Straight, 100% nitrogen is a poison! Instead, go to your local bike shop and ask for imported air. The hipsters are using Fiji air, but that's merely a fad. Better products are available from France and Italy, where fresh air is collected from some of the famous mountain stages in the Tour de France and the Giro. This makes your bike more than 10% faster, so bike shops employees often want to keep it for their own use. Go to your local shop and insist on imported air.

Don't let them bait-and-switch you into accepting any of those cheap CO2 cartridges, either. They're full of stale CO2 from New Jersey and they often infect your tires with Vittoria beetles.

Dr. Wally
