I ride non-stop since I am 4, my father gave me one bike each 4 years until 18. Since then I am changing components and assembling new bikes. Now I have seven, including tandem, home-made recumbent, fixed gear, city-bike with generator and internal-gear-hub, freeride full-suspension.
I have been bred on XC mountainbike (raced a bit), and enjoy technical terrain, as well as light freeride, randonneuring, and touring. I also like to try to smoke my friends and acquaintances on group rides (and so do them).
I tend to do my own assembling and mainteinence, and am known among friends for a natural willingness to solve mechanical problems "in the field", even those not on my bike. I like to read about deep intricacies in bicycle mechanics, being a strong fan of a lot (but not all) of Sheldon Brown approaches.
Recently, I am engaged on bike as transportation, bike advocacy, and political-related-bike-issues, and participate in a lot of local groups, mostly nightbikers, weekend rides (not club rides) and Critical Mass.
My short-term bike-related goal is to have equipment and energy to commute all-year round (my winter is very rainy), and my long term goal, more like a dream, is to be full-time involved with bikes, professionally (most probably designing/manufacturing or selling stuff).

Fixed Gear Chainring Centering Remind that these tight-and-loose spots may be caused by chainring, cog or the very chain being "off-center". If you spin the pedals with the bike upside down and there is not a regular pattern of tight-and-loose, perhaps even more than one part is off-center. That tends to happen more with cheap parts. |

Good locks seem awfully heavy At cafes, people usually keep looking at the bike, and cafes usually are in relatively safer neighborhoods, I think. |

Does frame size inside a particular model affect the ride characteristics of the bike? +1 for real world examples. |

Replaced Shimano Bottom Bracket, now front derailleur won't shift to largest gear Is the crankset the same? Some cranksets "sink deeper" in the bottom bracket, so if you have a different crankset, that might be an issue. Besides, even the same crankset sinks differently around different bottom brackets, due to spindle taper. If that is the case, do you think it's possible to tighten the bolt a bit more? That would bring the crankset closer to the front derailer. |

Why is cycling on a road so much faster than cycling on a cycle path? If we agree that, by design, road surfaces are constructed smoother than bike paths (which seems to describe reality worldwide), then I think this is the best answer. +1 |

Why is cycling on a road so much faster than cycling on a cycle path? Exactely the same thing in Brazil. (by the way, isn't this answer actually a comment?) |

Disabling back-pedal brake @DanielRHicks I also remember old, bulky bikes being ridden over and over and over and never having a chain replaced OR a chain-skip... Something must have been lost in the way... :P |

Disabling back-pedal brake Is there a WIRE activating the brake? Shouldn't the very backpedalling activate the brake, without need of a wire and a lever? Confusing... |

Is cycling better than walking to lose weight? Never forget the possibility to use the bike BEYOND your commute, since once you get minimally fit, you could get really far and/or really fast, having the bike as an extra, "free" tool to exercise (besides being an utilitarian mean of transportation). |

How to get back on the road again? Yeah, the roads I ride with these conditions have a ramp caused by new asphalt only on the main road, not the side lane. I'd say lightening the weight on each wheel going over the ramp is important, but I find a bunny hop is too critical if the traffic is that heavy as described. |

Formula to calculate Single Speed Chain Length from Chainring Size, Cog Size, and Chainstay Length (well, actually you have to get the radius from number of teeth, but that is "natural" too...) |

Formula to calculate Single Speed Chain Length from Chainring Size, Cog Size, and Chainstay Length Actuallly it's just move things to the right side of the equation, leaving "L" (chain length) isolated on one side. |

Formula to calculate Single Speed Chain Length from Chainring Size, Cog Size, and Chainstay Length And, just in case you want to find the "magic gear" for a vertical dropout bike, I think it's risky, since minor variations on the parts themselves can make the chain become too tight or too slacky... Not to mention the ideal length will quickly vanish as the chain wears out. (well, just a thought) |

Formula to calculate Single Speed Chain Length from Chainring Size, Cog Size, and Chainstay Length I have made a strikingly question before, although I wanted to find chainstay length while you want to find number of chain links. Should this count as a duplicate? bicycles.stackexchange.com/q/8608/2355 |
