Is my local bike shop asking to much money to change a rear cog? Maybe I have a really nice bike shop, but many little things like this I've found they will do this without charge provided you buy the parts from them. This summer, my LBS put in a new stem, while I waited. They also installed the new pedals I bought. The mechanic didn't seem too busy when I was in, so maybe I was just lucky. However, I think that if I had brought in a part that I had bought online or at another store, there definitely would have been some kind of labour charge. |

Air compressor to fill up to 60 PSI It does say how fast it will inflate a tire though. A mountain bike with 26*2 inch tires (660 mm * 50 mm) will (using pi*r^2 * length) have a volume of pi * 25^2*660 mm = 1295250 cubic millimeters which according to google is 1.295 litres. So at 40 litres per minute you could fill the tire from empty in 1.94 seconds. Of course the rating is for free air, without actually having any pressure, bu I'm pretty sure the tire would be filled extremely quickly, and possibly blow out, event if it didn't you'd have to overinflate then deflate to get the right pressure. |

Air compressor to fill up to 60 PSI I agree with @Adrian. The problem is that your tires are deflating. Unless you only use the bike once a month, then they shouldn't be deflating in between uses. If you only use it once a month, that's normal deflation. Using an air compressor won't stop the tires from deflating between rides. Also, air compressors, unless especially made for bicycles usually push a very high volume of air, leading to not being able to easily control the pressure. With many compressors, you could possibly blow the tire out in a few seconds, especially if they are rated to a pressure higher than your tire. |

Pannier for cannondale caad9? That Rivendell one specifically shows some kind of MacBook in the bag. Although it could be a MacBook Air. However judging from the measurements shown, it looks large enought for a 15" laptop (it appears to be about 15" front to back). |

Can I use a hybrid bike tire on my mountain bike? @freiheit: Yeah, but cyclocross tires are also kind of wide, usually around 34-38c. I was talking about something more narrow, like 25c. You probably won't find a knobby tire that is 25c, though you will find wide tires that have no tread at all. |

What type of bicycle would be the most suitable for riding in winter in the city? I've thought about riding in the winter (in Ottawa, still going this year, but alas, no snow) It never occured to me before, but a BMX seems to be a great idea. Has all the required features. Single speed, easier to bail when required,fewer parts, more heavy duty chain, relatively cheap. Maybe even a coaster brake would be a good option, do you have any experience with those, or do you use rim brakes? |

Can I use a hybrid bike tire on my mountain bike? Very useful. Tires of various treads and widths come in all different diameters. you will most likely be able to find a tire with the tread pattern you want in the rim size you already have. I think the only exception is that you won't find knobby tires that fit on a narrow road bike tire. Well, someone probably makes them, but they might be difficult to find. |

Tips for radial wheel truing In the Sheldon Brown glossary (sheldonbrown.com/gloss_tp-z.html#true) a wheel that is out of true vertically is referred to as being "out of round". Perhaps that's a better term for describing the problem here. |
