Finally went out to ride my bike again today. Last Friday, I'd walked to the local bicycle shop to waste my money on invest in various essential biking accessories, but the combination of bad weather, intersemester schedule lapse ("Are you staying up until 2 a.m. or something?" "Err..."), and the bicycle shop being closed Mondays meant I put off actually riding until today.

First, I went out to pump up the tires (first taking Dad's running stuff off the handlebars). Whereupon I realized I had no clue how much air they needed. So: up the stairs to my laptop and the Webbernets, which promptly informed me that (1) my bike was worth less than a meal at Taco Bell and (2) I needed to know the size of the tires. Back down the stairs, borrow a ruler, 1-1/8 inches is about 28 mm, and - back up the stairs - assuming 35 kg load per tire (reasonable) that makes 80 psi. Back down the stairs.

Then the helmet. I do most shamefully confess - after ten minutes of irritating helmet-adjusting, I simply gave up, pulled everything tight that could be tightened, and said, "Good enough".

(I also skipped putting on my LED taillight. Ironically, the headlight, which I did put on, was absolutely useless.)

After all the aggravation, I was quite glad to walk it out along the sidewalks to the nearest bike trail. And I was ecstatic to be riding again. There is very little I enjoy more than cycling - the effort required to maintain a pace my hindbrain reads as fast is quite easily within even my untrained capacities, even on (slight) uphills.

That said, I was feeling a little woozy after the first 1.5 miles, so I stopped in at a gas station to buy candy and energy drink. After that, I was doing quite well.

Anyway, in the end, I skipped the bicycle shop. After all, it was a cheap, old bike, and I was going to meet with some of me bro's friends (my acquaintances) and play "Left 4 Dead" at the internet cafe this evening. I'll go some other day.

Much fun, today.

You're funny. Everybody else I know would just put a little air in the tire, give it a squeeze, put a little more in ... rinse and repeat until the tire feels good and solid.

This is the first I've ever heard of someone measuring their bike tire size and calculating pressure based on that.

Well, I mean, I had a pressure gage right on the pump ... may as well use it!

'Sides, I don't know enough to tell whether the tire's under- or overinflated. I just wanted a ballpark figure, and I'd forgotten how stiff it should feel to the hand.

Usually it says on the edge of the tire what the correct PSI should be.

It may have, actually. There was a lot of mud on that tire.
