Tightening and loosening spokes on alternate sides by only a small amount in each iteration of truing. Remember that not only does the wheel need to be true side to side, it also has to remain round. And you can really screw things up if you over-tighten spokes. Many people have trued many wheels without having to use a truing stand. They do it with the wheel still on the bike. It's a good skill to have if touring. Then you can true a wheel on tour or on a long ride if needed. Err, my 'truing stand' is an old set of (28"?) forks.

I think my bike is plain wore out. I need a better bike, but everyone is out except those bikes costing $800+. Does anyone have any mountain bikes in stock? Andy I pick up my rim tomorrow which had one spoke replaced and it was trued. $11 And a Park Tool truing stand is only $299.95 :-) -- Cheers, John B. I built mine out of leftover plywood and angle aluminum. Errr... I was replying to a guy who had problems adjusting a Vee brake and you are asking him to build a truing stand? Horses for courses, as the British say. -- Cheers, John B. No worse than you recommending a $300 trying stand to a guy who?s not willing to spend $800 on an entire bike :-) Ah but I wasn't recommending, I was comparing the $11 he paid to fix and true his wheel to the $300 (actually $299.95) he might pay for a stand to do it himself. -- Cheers, John B. Truing a wheel in the bike is no less accurate, the result no better and no worse than using a truing stand. Building a series of wheels all day long under a good light in a nice clean truing stand and surrounding workstation is greatly more efficient and comfortable, but that was not the OP's problem. If I remember he broke a spoke and the wheel went out of true. Whereupon he took it to a shop that charged him $11 to replace the spoke and true the wheel. Which, if I recall, took a couple of days. Compared to locating a spoke that would fit, cobbling up some sort of gizmo to use for a truing stand, getting a spoke wrench that fits, finding the spring loaded clothespin to use with the fork if that is used as the truing stand and all the to and froing it would take for a guy who had a problems adjusting a brake to get the wheel trued I suggest that the $11 is not only the cheapest but the best solution. -- Cheers, John B. I agree he found a suitable resolution. but 'clothespin' ?? I'm not usually big on organic, natural and recyclable but for this purpose I prefer my left thumb. Use the spring loaded clothespin clipped to one side of the fork as an indicator of run out. see https://flatbike.com/truing-a-bike-wheel/ third photo down for photo of a commercial device with the finger pointing at the gizmos that the clothespin substitutes for :-) -- Cheers, John B. meh. I already own a left thumb and it's literally 'at hand'. But... with the clothespin one can use both hands to spin the wheel... Wheeeeee :-) -- Cheers, John B. If youve used the cone wrenches properly, you shouldnt need two hands to spin the wheel. PS: I prefer using a Sharpie to mark the high spots, then I dont have to remember where they are. A quick wipe of solvent on the brake track and youre ready for the next pass. But usually there are both low and high spots and it is usually better to attempt correct both problems as you go otherwise it is quite easy to have a wheel no run out but not centered in the fork. Particularly the rear wheel where the spokes on one side are at a different angle than those on the other side. -- Cheers, John B. I use the Sharpie on both sides of the rim to catch the outliers in each direction. If it’s a wheel that needs more work, I also have a dial indicator that mounts on my truing stand. Give the wheel a spin and the moving pointer gives a good indication of what the average location is, as well as the size and shape of the major wobbles. |

Yes, a proper dial indicator. I’m not sure if it’s calibrated, but I’m sure it’s good enough to true a bike wheel. I had it lying around for years, and when I built the stand, I noticed that the mounting arm had the same thread as some surplus IKEA table leg mounts, so I screwed those to the stand so I can move the indicator around. I hacked together a plastic “shoe”that fits on the end of the dial indicator shaft, so that I’m measuring the deflection over a small area instead of just at one point, and the whole thing works quite well. It makes no difference in real life, but it’s nice to be able to say to yourself “That wheel is true to +/- 0.010”. |
