The Complete Dummies Guide to Changing a Flat Bike Tire

All too often many instructional books or videos omit important information because the author or creator has mastered the skill and done the task countless times and forgets to include the truly obvious things that confound newbies.

This is the way it is for me with changing a bike tire.

I was venturing out into the world today on my first longer ride with clipless pedals when I felt my tire go over something and then felt that ominous bumpy feeling. And once again, looking down, I confirmed my suspicions: My tire was flat.

Unlike that ride last year when I had no cue as to how to remove my rear tire, I am now an advanced newbie! I removed my rear wheel (hint: You should put the bike in the lowest gear and loosen the rear brakes first).

Then I whip out my tire levers, spare bike tire, and CO2 cartridge. I was in a residential neighborhood and a guy mowing his lawn stops by and asks if I'm far from home and if I know what I'm doing. I reply that I'm not far from home and I try to act like I know what I'm doing. I even think I remember what to do from watching YouTube videos.

I remember that one must insert the tire levers into the tire bead. (Hint: First let ALL AIR OUT of the tire. Then, go around the rim and push the bead with your thumbs, making it easier to remove.)

But in the process, I break both tire leavers and get frustrated. I call my husband, but we're not having a good day, so I decide that I'll get my own self home. I prepare myself for a long walk and a slow ride....but then I remember the CO2 cartridge and put it into the tire. This gives me enough air to get halfway home. Then, I proceed to do a slow ride home.

After watching more YouTube videos and analyzing the situation I realize what went wrong. Most videos and other instructions neglect to show a close up picture of HOW TO INSERT THE TIRE LEVER!!!! Start near a spoke. The curved part of the lever hooks under the tire bead. The little hook at the bottom hooks around the spoke. Did I mention that all air must be out of the tire before you start??!!!

Below are some good YouTube videos on how to fix a flat tire:





Here are step-by-step instructions from eHow.


Glad this occurred on a ride around the neighborhood, rather than a long out-and-back ride. Now, I'm truly ready to venture out into the world. After all that, did I mention that I did fine with clipless pedals? :)

Clipless Pedals

You click your right foot in
and twist it right out
You click your left foot in
and twist it right out
You click booth feet in and turn them all around
That's what it's all about!

Right after the Howard Life TriColumbia 75K ride, I decided the time was right for clipless pedals. One Friday afternoon, I walked into the bike store with my bike and shoes and announced that I was going clipless.

I researched various pedal systems online and took note of what others use. In the end, I chose a Shimano SPD double-sided pedal system because I liked the idea of recessed cleats that I could walk in when I got off the bike. In a sense, I made the choice of pedal systems a while back when I got mountain bike shoes.

The store installed them for free and then mounted my bike on the trainer so I could try them out. Everyone standing nearby in the store had a story about falling off, which really inspired confidence, and they suggested that I practice in a parking lot. The store staff person told me that the hardest part was to know where the cleat was without looking down. It would be easiest to get my foot out of the pedal at the bottom of the cycle, he said, although I could exit at any point. I had a hard time detaching my foot from the cleat, and the staff person loosened the tension. After that it was much easier.

After a few tries in the store, I headed to the parking lot of a nearby elementary school. I clicked both feet in. "This is great!" I thought. And then when I couldn't get the second foot out, I fell, coming down hard on the bar of the bike and skinning my elbow.

As I recuperated from the fall, I naturally did some Internet searching on the subject and asked for some helpful tips. Here are my favorites:

* Practice on the trainer. Click in. Click out. Do it 100 times. Or, put your bike in front of the TV and clip in and out while watching TV for the evening. Build that mind-foot connection so that you can clip out when you think of it. Like twisting a doorknob before opening the door. Hint: I find that it helps to press down a bit and then rotate your foot out.

* Practice in a large, flat parking lot. Clip in only one foot at at time and practice alternating your feet. Then practice clipping in and out with both feet. You do not always have to be clipped into the pedals.

Today, I practiced in the morning on the trainer, and then rode around in a nice big flat parking lot. I tried one foot, then the other. Then both. I didn't fall once. And I'm crossing my fingers.

Postscripts

On the weekdays, I once again alternate running with cycling and each session, I make it a goal to clip in and out 100 times, alternating feet, going fast and slow, and pushing big gears and small. All this while watching Fuel TV which gives me an interesting perspective into the youth counterculture of extreme sports.

On Memorial Day weekend, I drove my bike to an industrial/office area which features a lot of large parking lots. I started out in the parking lot, practicing with my pedals. Then I drove around the 2-mile loop a number of times and then practiced with some stoplights. Another successful ride. I can't wait to go on longer rides again.

A New Kind of Pain at the Pump: Credit Card Fraud

I am by nature a very routine person.

Today, I left for work. As soon as I got in the car, I remembered that I was down to a quarter tank and needed to fill my tank up. So I made the trip over to my favorite gas station at the local village center. I've been going to this gas station for years because it's easy to get into--not like the other gas station closer to my house where you need to squeeze past parked trucks and perform some complicated driving maneuvers to get into an open space at the pump. At my favorite station, I drove right up to the same pump I always go to and then swiped my credit card into the machine.

And that's how I became a victim of credit card fraud.

As I was driving to work, my husband received an automated phone call from the bank saying that my credit card account had been flagged for fraudulent purchases. He sent me an e-mail asking me to go online and check my account, saying that there was a problem with it. When I went online, I had trouble getting into the account to check it, so I wrote down the number and called the bank.

I was asked if I made any Internet purchases that morning, and I said no. I was asked if I'd used the card, and I was prompted to recalled the gas purchase on the way to work. I was told that several small purchases were made on the card to test it, and then Internet purchases were made. The fraud was detected and the card was shut down within an hour of the purchase. I'll receive paperwork to erase the fraudulent purchases, and I hope it will not be too much of a hassle to rectify this.

I couldn't believe that the gas station had stolen my credit card information. I've been going to this gas station for years, and I plan to take this up with the gas station manager tomorrow.

Card Skimming
Out of curiosity, I did a search on Google and found out that what happened to me is part of a growing problem. The majority of credit card fraud occurs at gas stations (61.6%) and drug stores (14.3%), according to a Google summary of a Science Direct pay-per-view article.

At gas stations, thieves can install small skimming devices at the gas pump that are hard to detect which steal credit card and debit card data, According to an article in USA Today. The skimmed credit card data is then used to create duplicate credit cards that are used at the victim's expense. The theives will "test" the card with several small charges, and if the account holder doesn't shut off the card, much larger purchases are made, according to David Loshin's blog. Banks and credit card companies use algorithms to flag cards with suspicious purchases and card activity.

Some police departments are trying to place sticker seals on the pumps that gas station employees check daily...that's if the gas station employees aren't the cause of the problem. Other gas stations now require customers to enter their ZIP code, according to a story in The Boston Globe, because a thief is not likely to know the ZIP code for the card. This may be an especially effective deterrent in suburban locations where there are several ZIP codes in close proximity. I recall being asked to enter my ZIP code at another local gas station, but not this one.
