Tracking problem
I finally found the root cause of my problem with the bike not tracking
properly. Trek hybrid, no shocks, tires are 700x35c just a touch of crosshatching treat, almost looks bald. The third lbs guy to look at it spun the tire and said 'you have a shimmy in the tire. The tire may have been put on incorrectly and the bead of the tire might not have been in the rim straight'. It's a small and hardly noticeable section with the tire is off true for about 8 inches, and it's definitely the rubber tire portion, but you have to spin it a time or two if you're not used to looking at tires. He said he spotted it when spinning my front wheel and checking the brakes. This guy was really nice, b/c he gave me a quick tune up while putting on my SPDs. If he'd looked like Halle Berry, I'da...well, you know. ;-D I noticed the lack of tracking when holding the back of the saddle and trying to roll the bike forwards. Despite my trying time after tme to do this and keep the tiny bit of correction going with tilting it, this bike will -not- track straight; thus I can not ride it without hands, and you -need- to be able to ride no hands when you're going over 90 minutes to two hours, imo. If this doesn't fix it, maybe the headset needs examined or something. So I'll have 'em look at this, and probably change the tire. -B |

Huh? How'd you get that opinion? I'm curious too. My first bike wouldn't ride no-hands at all. Not even a little bit. I rode a double century on that one (10.5 hours on the bike). -- Dane Jackson - z u v e m b i @ u n i x b i g o t s . o r g "I don't see anything wrong with being arrogant and not at all helpful." -- Paul Tomblin |

Huh? How'd you get that opinion? That's so you can sit up and stretch your back, change your gloves, get somthing out of you back jersey pocket. I used to be able to ride for 5-10 min at a time no hands, totally stable on my old steel Sears&Robuck schwinn-style twelve-speed. Most old timers will say 'sheesh, if you're not in a race, pull over sit and eat'. But guess what? At some point you'll want to eat on the bike or change your gloves or shirt, and if you don't practice it, you won't be able to do it. It's also nice, if you need to clean your glasses, and you've brought some tissue, after a rain storm. Part of bike handling 101 regardless; iow, you may never -need- to use that skill, but you should have it and be comfortable doing it, imo. I picked 90" to 2 hours as the point at which some ppl start eating and drinking during the ride. You say 3 hours, I don't disagree. -B |

You say 3 hours, I don't disagree. Well, it's your opinion. I'm of the opinion that if I need to stretch or eat or whatever, I'll get off the bike. I'm not a pro so there's no need to do other things while riding. I don't need the hassle of getting hurt needlessly. Income to protect, responsibilities, etc. YMMV. BTW, I usually get off the bike at about 20 miles, so your 1.5 hours is about right for me. |

I don't need the hassle of getting hurt needlessly. Income to protect, responsibilities, etc. YMMV. Not trying to be argumentative, but I don't expect to fall off the bike at speed, but I still ride and I go down hills and reach 35mph. That's gotta be more dangerous than riding no hands to get something out of your jersey back pocket, such as a dispo. camera. BTW, I usually get off the bike at about 20 miles, so your 1.5 hours is about right for me My experience may be different, b/c I don't equate riding with no hands as dangerous at all, given you don't pick the wrong time or part of the road to do it sparingly. I'm not advocating riding that way to impress the babes or anything. It isnt' even so much that, as it's irritating to -not- be able to ride no hands, even coasting, and take off your sunglasses and put on your spares. So you telling me you're just over-cautious, or that never having done that you have none of the skills. You'll never get on a unicycle, then? Just askin', not trying to be a butt. I've never even come close to getting hurt or even a hint of it, and I used to do it a lot with my paper route. I'd fold the papers while riding and throw them up on the porch. As I said, it's part of bike handling, imo. Sure, elect not to do it much, but don't totally avoid having the skill set. -B Several of my cycling books talk about it, and one mentions it's necessary skill, but not sure of their context. I'll look it up if you like. |

The only time I don't do it is when I'm in a pace line. I don't use aerobars then, either. I think they're pretty equivalent. I'll sometimes ride a 30 mile loop entirely in the aerobars. I did it once no-handed just to see if I could. |

Tell me you rode a double century and didn't eat on the bike? Didn't want to sit up once and arch your back? Gnarly. -B |

I went through a bunch of clif bars, some sandwiches, juice, water, etc. I can do all that one handed just fine. Heck I used to reach into my trunk bag side pocket and pull stuff out with one hand on the bars. Didn't want to sit up once and arch your back? Gnarly. No actually.
