View Full Version : Wheel out of true

I was adjusting my brakes on my bike tonight, and noticed my front wheel is slightly out of true. About 1mm in one spot.. they are Ksyrium SSC wheelset. Are these wheels much harder to true.. with only this slight bit out of true should I truly worry about it? I'm not perfect at trueing wheels yet, so good chance I would make it worse by doing it :) Just the thought of them being out of true bugs me. The wheels are roughly 1.5 years old right now.

If you have the two tools it is no different than any other wheel. There is one to keep from twisting the spoke and the other is splined to fit the nipples.

Yeah I have the tools in my garage.. still sitting in their bag. Every wheel I've plaid with has been standard 32/36, I'm just a bit nervous to touch these. I guess if I make it worse I can just take it to my LBS.

I would not sweat it to much, 1mm is just a quarter to half turn adjustment. If you find your self turning spokes like a madman, then step back, think about it and maybe take it in to a shop.

OK, newbies, this guy is talking about a low-spoke road wheel, not some 36-spoke ATB wheel. Over-torque a spoke on these, and you've got a $200 piece of wall-art.
Kev, if you need to ask, you shouldn't be asking here. I'm sure Ksyrium has some literature on the subject and they are the ones you need to be asking. For a good wheelset like yours, spoke tension is critical and a tensiometer is something you should consider investing in.

Probably not worth messing with.

Unless the out-of-trueness is right at the spoke, which I doubt, you will have to finess at least two or three different spokes to bring it into true. The odds of making it worse far, far exceed the odds of making it better. For 1 mm, I don't think it's worth it.

I have been thinking about investing in a Tensionmeter lately, especially with the new park one only being $50 now. I know 1mm seems like so little, I did not even notice it when riding my bike earlier in the day, just when aligning my brakes. I enjoy working on my bikes, but if it is much harder to true this wheel I might just take it down to the LBS. A older wheel that is worth less then $100 I don't mind trueing and is good practice, but on my $700+ wheelset.

I am a newbie to this forum but not to bikes, it is how I make a house and car payment. I have built more than 700 wheels(including rebuilding Kysriums and Shimano's min. spoke wheels.) I do frame repair, restoration and, with my wife, do custom paint. It is just a wheel, pay attention, be careful, make small changes.

Should you true the wheel perfectly Murphy's law states that the bladed spokes will no longer be straight :)

You get a special tool with the wheels to true the wheels, so you can keep the spokes in correct position.
