Thanks for that, I'll look when I go today.

I've never used a compressor, I have a Bell hand pump I use.

Newer, better quality bikes have "Presta" valves instead of the car type "Schraeder" valves.

Many people will tell you that Presta is better....Presta was designed for bikes. It's narrower, which allows it to fit on thinner rims but that's really about it.
I've seen bikes with the holes drilled out to allow Schraeder valve tubes.
You'll either have to get a pump that will work on Presta valves or an adapter. They are easy to find and are cheap. Probably a dollar or two at Walmart...

If you are going to a bike store or Walmart you might want to consider a new pump, one that allows both type valves.

You should never use an air compressor on bike tires. The air volume in a bike tire is very small and you will at some point blow an expensive tire using a compressor. That is an expensive lesson as you'll surely buy a pump after that.
That said, I'd like to see a poll showing how many people use a compressor...

I brought this back because I have another issue with my bike. It sounds pretty retarded (I know), but I can't air up my tires, the valve stems are different than I've seen before, is this common for road bikes? This is the first one I've ever had/ridden and I was all excited and can't ride it because my bike pump doesn't work on them?? Any ideas or thoughts??

A suggestion for informal bike stand - Hang it from the ceiling.
Two hooks in the ceiling, nicer if you have garage or basement. One rope from a hook to the handlebar stem and one from the other hook to the saddle - you're all set.

To work on your bike just turn it upside down and let it balance on the seat and handlebars. You can adjust it and clean it like this.

Do you have any friends who ride? Can they duplicate the problem? It may just be a shifting issue, especially on the cheaper bikes. The DWs MTB has a front der issue but it's only because she's not quite got the knack of shifting it just yet.

If you don't want to fix it yourself, take it to a bike shop and get it done (and see if you can watch). Front Der adjustments are easy for a bike mechanic. They aren't that hard to do for normal people either, PERRYR has a good link for you to get instructions...

Here's a great article that will help you set up your front derailleur.

I suggest getting a decent book on bike maintenance. Many many people are going to tell you how only their local bike shop can be trusted with the care of their sophisticated machine. The reality is that it's a bike. You can do all the regular maintenance yourself.
Maintain it and care for it, even if it's a cheapo. All bikes have similar components. Better derailleurs are set up and adjusted just like the cheap ones but are easier to adjust, work better, and last longer (both the part and the adjustment.
I suspect that your bike has a loose front cable or the derailleur moved out of position. Or it was left in the rain, cables frayed, gunked up......

A general suggestion to anyone that is looking for a bike but can't afford a good bike, that used bikes are a better choice than a cheap new bike. Learn how to maintain it yourself and you'll have a high quality, reliable bike.

I am not an expert but you are right it takes some adjustments to some screws to get it right. I got lucky and a friend who likes bikes will fix and or adjust my families bikes anytime I ask. I do watch him but haven't attempted it myself. What I would suggest is to find some youtube videos that will show you how to do this. It will help.

Hello all, I am having an annoying problem with my bike and really don't want to pay to fix it. It is not a fancy bike, just a basic $100 bike. I decided I would pay for it and now I can't find a decent priced shop to take it to in my area.

The front has 3 gears (1,2,3). When I am riding I have trouble getting it to go into all 3. It likes to stay in the 2nd gear. Every now and then I'll try to shift and it will go into one or the other but not both. I've read online that you just adjust some screws to tighten up this sort of thing. So, if you are good at this, I'd love details. If not, hears a specific question: what can I use to hold up my bake so that I can turn the pedals and work on it without it touching the ground. I don't have a trainer or anything like that.Any ideas???
