Cost of maintenance of a roadbike For $10-$20 you can pick up the tools to do the tune-ups yourself, including brake and gear adjustments, replacing brake pads, and checking all the important bolts to make sure they are tight. They pay for themselves after the first use. You won't be able to replace the cassette, or replace the cranks but most of the regular maintenance you should be able to do yourself. |

What tools on a multi-tool do I actually need? The only reason I could think of for having a couple tools you don't need is to help out other cyclists when they have an issue. It's amazing the number of people who will ride around without any tools at all, or will ride around without some tool they need because they forgot about that one bolt or screw that uses that specific tool. You could probably bike for years without needing a screw driver, because the only thing you'd use it for would be your derailleur adjustments (why haven't they switched to allen keys?), but it doesn't take much extra space to carry around a couple extra things. |

Why are single-speed bikes with disc brakes hard to find? In many jurisdictions, it's illegal to sell bikes with only a single brake (and rightly so in my opinion). A fixed gear plus a front brake would get the job done, but if you have a single speed, it's advisable to have both front and rear brakes in the even that you have a cable break, or have some other kind of brake failure. Even on my fixie I have both front and back because in an emergency situation you don't have time to get your feet into the position for skid braking, not to mention the increased stopping distance if you have to brake with your legs. |

Saddle or frame shape for painful Coccyx? Moved. Like I said though, I really don't have any experience, and don't know whether it would fix your specific problem. So it might be helpful to wait around for a bit to see if you get some better suggestions. |

What is the width of Giant CR41, 32-hole rims I still don't think you'll be able to figure out the size without measure, mostly due to the bike I linked to which had CR41, 32 hole rims with 25 mm tires. CR41 is most likey just a code that determines the material and other feautres of the rims without restricting it to a single size. Kind of like how there's many different sizes of Continental GP 4000 tires. You'll have to measure if you want to know the size. Also, a ruler is probably not a great tool to use, since as @DanielRHicks said, you need the inside measurement. You'll need something that can fit inside the rim. |

What is the width of Giant CR41, 32-hole rims From what I'm seeing, those don't look like the original tires that would have come on that bike. The Giant TCR 2 is a road bike, that currently comes with 700x23 tires. This bike model came with CR41, 32 hole rims, and 25 mm tires. If these are the rims that are on your bike you'll be fine with 28mm tires, and it's likely that somebody put the largest tires they felt they could safely put on the existing rims. |

What tools on a multi-tool do I actually need? 30 tools? Does that include 30 distinct types of tools, or 30 tools once you add up the various sizes of allen keys and spoke wrenches? Also, along with what @PeteH said remember to put you tools back in your carry pack after trying them at home. I actually have 2 sets of tools for this reason. Too many times I've forgotten to put the tools back with my bike stuff after fixing something at home. |

How to calculate bike stand-over height using frameset geometry and wheel radius? @DanielRHicks Yes, It would most likely be possible, these numbers don't show that value. If you had a picture of the frame, you could probably estimate it based on some of the other measurements. Although now that I think about it, if you had a decent picture of the bike, you could probably get a good idea of the standover height from just one simple measurement and inferring the scale of the picture. |

What should I look for in an indoor cycle trainer? Actually, My Cyclops Fluid2 is a mid-range trainer that doesn't have any difficulty adjustments. however, the gearing on my bike provides more than enough range for my workouts. |

Can a chain-lock be better against cutting than a U-lock? Even if it didn't swivel, you could cut it at the bottom of the "U" far from the shackle, from there, you could probably get enough leverage with your hands (or hands and feet) to bend it sufficiently to remove it from the bike. |

How to calculate bike stand-over height using frameset geometry and wheel radius? Seems like it would be impossible without having the angle of the top tube. If you think about just dropping the top tube to a lower height, you could do that without changing any of the other numbers that are given. |

Evaluate hill gradient I have an Oregon 450 which is a lot cheaper than a Garmin 800, and it gives me readouts of meters/minute or meter/sec as my "climbing speed". It has a barometer in it, so it's supposed to be more accurate than just GPS for altitude. I'll have to keep an eye on that next time I'm doing a climb to see how well it works. |

Is having your hands “on the hoods” of drop handlebars safe for braking? I have a touring bike which has a much more relaxed posture, while still having drop bars. This allows me to ride with my hand on the drops most of the time. It's a little less aerodynamic than a road bike, but a lot more comfortable. |

Evaluate hill gradient I do use Strava and like it. They do kind of put an emphasis on comparing you against others, which can be both fun, if not a little demoralizing. They break up your ride into different sections that allow you to see how your time compares to others who have done the same climb. You can just ignore the standings if you want. |

Evaluate hill gradient Strava is another popular site that you can upload your GPX file too. They offer quite a bit for free but also have some advanced features for those willing to pay for a membership. |

High pressure water cleaning and chain lube Yeah, if you're a pro mechanic working on pro bikes, and your components are provided as part of you sponsorship deal and replaced frequently, go nuts, it's the fastest way to clean a bike. But definitely not recommended if you want to improve the longevity of your parts. |

Does frame size inside a particular model affect the ride characteristics of the bike? Along with the first comment, I would venture to say that if it's true for the smallest, it's probably true for the largest, or if you change the stem, drop the bars a bit, or if slide the seat forward a bit. All these things can change how a bike feels. The fork is always the same size to accommodate the same size wheel and allowing the brakes to reach the rim, So you can't really just scale a bike and have different sizes have the same feel. If you can't test drive the bike, perhaps you can persuade them to do a free fitting, with a free stem exchange to ensure it fits you as best it can. |

Italian bottom bracket Shimano BB-6400 fixed cup tightening - what tool? @alex How does that allow you to measure the torque? Seems like it would be very easy to over-torque something when using the frame as a giant lever. |

Number of gears for a racer Probably worth noting that the number of gears on the cassette (in the back) won't do much to determine the "range" of gearing, but really determines the size of steps between individual gears. I have an 8 speed (11-32) with way more range than most racing bikes, but the gears are further apart so I sometimes feel like I can't get in the right gear. It's likely that an old 14 speed bike will have just as much range as a modern 20 or 22 speed racing bike, but the steps between the different gears will be much larger. |
