Wheel wobble
Have just noticed that my rear wheel has a slight deviation when on the ground - approx. 1mm either way.
My brakes are 1mm from either rim.
When the bike is suspended and held there is no discernible lateral movement. The spokes appear to be equally tensioned with the drive side slightly tighter.
As I'm doing a sponsored ride week friday should I have it looked at? or am I being over cautious?.
I've not noticed any judder or handling probs. prior to the discovery.

your brakes are a bit to close if their only 1mm from the rim....you wont be getting the full power from them - mine are around 5mm each.
1mm of wheel movement isn't terrible - a good wheel builder will be able to true that out for you; good idea if your unsure.
drive side spokes are generally tighter then no-drive side due to the rim off-set, nothing to worry about that0 -

Not sure what your "..on the ground." comment means. Also noticing 1mm without the wheel being in a truing stand is guesswork.
Same guesswork with "...spokes appear to be ...".
Brake pads are way to close at 1mm.
If you have wheel issues, and it worries you, or even think you have them then find out, but guessing won't tell you a thing.0 -
'on the ground' means the wheel is situated on the ground, and the wheel moved on the contact point pivot.
re spokes, as I don't have any way of quantifying the tightness of them that was my best guess as I didn't think that putting a number to the value of tightness would help, other forums suggest you test the tightness of spokes on a weekly basis and pther than having a tightnessmeter how else can you get an indication.
1mm is 2.5 times the width of the '1' so for me it allows precise feathering of the brakes., so in total 2mm within which parameter the wheel runs true. To my mind 5mm either side (or I - I) either side seems quite a long way from the rim, but each to his own eh.
The only reason I gave indications was so that I could receive an answer within normal parameters - is the situation within normal or way outside giving cause for concern.0 -
Out for ride today - great being semi retired - decided to pop into LBS on way home.
Problem boiled down to the rear drive side dropout being loose, tightned up and on the way all for free so thumbs up for steve at Yarm cycles.0
