Friction gear systems are a lot simpler to adjust, because the movement of the derailer cable can be modulated as you ride, every time you change the gear- they require less cycle maintenance. Modern index shifting systems are a little more complicated because each ‘click’ must release the exact right amount of cable to allow the derailer to move the correct distance to move the chain from one gear to another. Setting up and adjusting a derailer is not difficult and requires only basic tools, but there is a methodical procedure to follow.
On a very sunny Saturday I had a rear spoke break - you can imagine that no shop was willing to promise a quick repair! I was so fortunate to find this shop and will come back - Andy not only told me to come down and he'd get it fixed, he had his assistant work with another couple while he measured, cut to the right size, installed and trued the wheel while I waited! It was awesome, and the whole place had a great feel and good people. Best of all he charged a very fair $20 for all that work - I would have paid a premium for the quick service! After experiencing lots of attitude at other shops and poor service, this was a real find. I hope you will check them out, they have a great selection of bikes and accessories too! Good people and good craftsmanship should be rewarded.
It’s both surprising, and not, if you think about it. The way I’ve usually seen it happen is first the rear tire goes flat, then the front one. My theory is that both tires went through the same pile of glass/thorns/metal bits and they both picked up junk. the reason for the flat occurring on the back first is because there’s more weight on that tire, so the offending article works its way through the tread more quickly.
Whether you ride a single, 7, or 10 speed bike or anything in between, you will need a slightly different chain. The major difference is that they come in varying widths to accomodate the different spaces between the gears, but quality of construction is also a factor in choosing a chain. Inspecing the chain should be a part of your regular cycle maintenance procedure- It’s important to keep a chain well lubricated, but oil will also attract dirt and so different oils for specific riding conditions are available. Remember to clean your chain regularly to get the longest life out of it and the gears.
