Wheel trueing

[gbb]

Or is that truing ?

Give it a go....i just did with a hopelessly buckled old MTB wheel and i'm amazed how easy it was to get somewhere quite near true, with the minimum of fuss. I just upturned the bike and used that as a stand.
From approximately 10mm buckle to 2 mm in places...easy. Just going to tweek it now and see how it goes.
Read Sheldon Browns page first or there's plenty of other tutorials.

Find and old wheel...give it a go

No. They are both correct versions. The originating final 'e' is commonly dropped in US usage [judgment/judgement] but in this case both spellings are common in the UK.

So there.

In that case I stand corrected

Oh no, now you've done it. You'll get Andy in Sig starting his ranting again now . .

I trued my front hybrid's wheel today it's actually easier than you might think once you've got the giste of it, it was quite a bit off which meant I couldn't have my brake pads that close to the rims or they'd rub. I didn't intend on doing that today, I had noticed my multitool had a couple of spoke keys on it so was just seeing if it would fit and ended up truing my wheel. It's weird though I made a bit of a ballsup at first, you don't twist the nipples (oo-er!) how you think you should it's the opposite i.e. I expected tightening the nearside spoke would move the wheel away from the brake pad, when it's actually the opposite - you have to loosen it and tighten the opposite side. It's much better now, I just hope nothing nasty happens during my commute to/from work tomorrow, like the pinging of spokes followed by lots of swearing .


I found this video more helpful than others I have seen:

Apart from going to silly extremes spokes will normally break if they have too little tension, not too much. The maths showing how a wheel supports its load and why this oddity is the case is available on the web, but don't bother unless you enjoy maths!

Which is weird because I was taught to lace a wheel with tension two thirds the way up the range.
I have never had a failed spoke, unlike the 'factory' wheels where the spoke tension is right up at the top limit.

Interestingly, I was taught by a lady who worked in Wheelbuilding at Dawes Cycles, Wharfdale Rd, Tyseley.
When I bought my Dawes Giro 500, I took the wheels to my LBS and they checked the tensions. The tensions were about 80% of the range, so I loosened them off there and then to 70%.

The spoke tensions on new Treks, Spesh and LeMonds were at over 90% of the range according to the DT Swiss manual.

Several Solihull CC members sufferd broken spokes on their Treks on Sunday rides.

Sounds much like I was shown, 40+ years back by a chap who'd done that at Holdsworth. His rule of thumb was that on normal bikes spoke tension should be about three quarters max. He said they shouldn't be much above that to allow adequate margin in use. In practice I can't measure the tension and have to judge from the note they make when dinged, which when I have had them measured means roughly 50 to 80 %max.

The only time I've ever had more than an occasional failure was going up a hill in Devon when 6 at the back went! I got a bike shop in the next town to check the wheel and the tensions were indeed far too low. Spent a couple of hours at the yoof 'ostel that night sorting it out, and have never since neglected my wheels. If the range of notes when dinged is too great then I pay to get them re-spoked and set up properly.

Wheel trueing is the one thing I don't bother with myself. I had a go once and didn't fare particularly well. I just take it to the LBS now, I've not the patience for it.

Had another go at a really warped budget MTB wheel, just for fun. Bugger, it's 100 times better. Useable on a cheapie bike, i'm getting addicted

To true laterally isn't too difficult but it becomes more difficult when roundness, dishing and spoke tension have to be maintained.

I have a small buckle in my back wheel, will give this a go later the the week!
