Wheel true or not true?
Question: If my rear wheel were not "true" could it feel like a rythmic
thump or vibration? I have noticed these feeling since I put this wheel on my road bike, a few hundred miles ago. Ken -- More of my mind dribblings: http://mind-dribble.blogspot.com/ And my homepage: http://kcm-home.tripod.com/ |

Ken -- More of my mind dribblings: http://mind-dribble.blogspot.com/ And my homepage: http://kcm-home.tripod.com/ I would think it more likely that you have a flat spot (as opposed to the wheel being "out of true" horizontally). Most truing stands have a gauge/pointer thingy to determine this. If it's bad enough to feel, I would guess it's bad enough for you tosee it with the tire off and the wheel spinning. |

thump or vibration? A regular thump-thump-thump is from a flat spot or bulge in the tire. An out-of-true wheel wobbles laterally -- spin the wheel and watch the rim at the brake pads. RFM |

In doing so, you may see that the cause is something else. The eyes are a much more precise diagnostic tool than the posterior in most cases. -- My email address is antispammed; pull WEEDS if replying via e-mail. Typoes are not a bug, they're a feature.

With the wheel off the ground (hang bike with rope. etc.), spin the wheel and sight along rim and brake pad to see if the wheel is out of true in the vertical plane. Make sure the tire is mounted evenly. Wiggle the wheel to detect any bearing play. |

Well i did that and it was pretty apparent that it was out of true, I worked the spokes a bit with it still mounted on the bike and it "looks" alot better, I need to ride it to see or feel if it still has the thump.

once i put the tube in some weird way and the valve stem made a huge
bump in the outside of the tire, though that was probably on an older bike with schrader valves. you could not see it on the outside of the tire but it was harder in that spot and you would definitely feel it every time the wheel turned. i think what i did was to get the valve between the wheel and the tire somehow. wle. |

Well this is an old bike w/schraders as well, and after I worked it on the rim a bit, my eyeballs tell me it is truer, and I notice the thump has lessened. I am sure the rim is not completely true due to the method I used. But it is better than it was, and what is left could be in the tire / tube themselves, or like someone else replied it could be a flat spot on the rim. I think a new wheel is probably in order. |
