Bicycle Mechanics - Rear wheel not staying true

Hey guys,

I just did a search on the forum and came up empty-handed. I have a Royce Union road bike just like this http://oldtenspeedgallery.com/blog/wp-content/bikes/owner-submitted/lucas-royce-union-supreme-10.jpg and my rear wheel was recently replaced and it was perfectly straight to start off with and was great. But it's only been about 50-60 miles on it now and it's beginning to wobble off-balance again.

I was just wondering what is causing this and how I can stop/avoid it. I ride on some bumps every now and then but nothing extremely major on the roads I take. And im not a huge guy if weight could be a factor, around 165-170 or so.

Just wondering if anyone could shed some light on this for me.

Thanks in advance :)

Your wheel needs to have it's tension checked. And by checekd I mean brought back to spec + normalized. And then stress relieved and re-trued.

Check to see that the spokes have enough tension and that the tension is even on each side of the wheel.

I will do so :) thanks guys

Low, uneven spoke tension is the main cause of a wheel going out of true. Aside from hitting something hard enough to put a large stress on the wheel. A wheel with spokes tensioned at or near the max the manufacturer recommends for that specific rim and with the spokes on each side having even tension ( less than 20% spread - 10% is better) will not only stay true longer but is stronger and more durable.

Thanks guys...I finally got to sit down with it for a handful of minutes and simply tightened up the areas of the wheel that needed it and it is pretty much perfect again :)

Thanks
