Bike tire changing practice on Sunday
Bike tire changing practice on Sunday.
I have a spare tire tube for my road bike, and handy foot pump, preparing for a flat tire, but I haven't used my handy pump. I put air in tire with a bigger air pump at least once a week, keeping pressure near 8bar.
I have viewed a few time videos about how to fix flat tires, changing tubes and tires, but I'm not sure I'm able to do actually. I had been thinking that I need to practice how to attach the tube and tire to the wheel rim. I was reluctant because my bike was much more stronger to flat tire than as I had expected it be, as long as I keep air pressure regularly. I didn't want to intentionally take the risk of having flat tire by my poor skill. Finally I decided after I had flat tire on the way of annual maintenance, and fortunately the shop noticed it and fixed it.
It was 11:30 a.m. that I started the training. I detached the front tire from the frame, deflated it, and detached the tire and the tube from the wheel completely. I used 2 tire levers to begin working with the tire. It wasn't good time to begin, because I had to have lunch on the half way of the work. I moved the wheel, the tire, and the tube temporarily indoors to have lunch.
After I had lunch I restarted my training. It was time to attach the tube and the tire again instead of changing, because there had been of course no problem with the current tire and tube. Before I began put the tube into the rim, I inflated a little to get rid of twists of the tube. I put the bead of one side into the rim, then put carefully the tube within the rim, so that the rim wouldn't bite the tube. Now it was time to put the bead of the other side in the rim. I had viewed the videos of how to, but where to start varied by site, so I began with the area near the bulb. I made sure the label of the tire was at the position of bulb. I put the bead in the rim carefully again. It seemed that the tire was somehow attached, but there seemed to be something wrong with near the area of bulb. When I watched a video carefully, then they nipped bulb, and moved up and down to adjust the position of the tube. I worked carefully again. It looked all right for that time.
Tire attachment section (probably) completed. Then the turn of my portable handy air pump. I could have used bigger air pump and I could have done more efficiently, but it was a simulation of flat tire solution on the way, so I should inflate with my handy pump. It was so small that it was really hard to inflate. Finally I pumped 110 times (I intended to pump 120 times, but it was really hard to pump any more), and got the pressure of 6bar, 90psi, enough pressure to ride again if I ride carefully enough not to give great shock to bike on gaps.
This work will actually be required when I cope with a flat tire, or changing tires or tubes to get higher performance. The more used to I get, the more secure I feel when I ride longer as long as I have enough equipment on my ride.
