I am new to fixed gear so sorry if this is a stupid question; that has been asked a thousand times, or has a very obvious answer.

I have a old road frame with 125mm spacing between the rear dropouts. I am planning on buying a wheel with halo track hubs which have 120mm spacing.

Will the axles on these hubs be wide enough to fit my frame; and if not is there a solution.
Sorry again if this is a stupid question.

Yes they will fit your frame. You need to (or at least should) get 5mm worth of spacers to make it fit perfectly. Since you are making a conversion you may want to put more mm of spacers on one side than the other to help get a better chain line (the straightness of the chain between the cog and chain ring).

You should go to sheldonbrown.com for help in the future. Its going to tell you 99% of things you need to know about fixed gear conversions.

Hm, you're going to be cutting it close, but depending on how wide your dropouts are, it should Probably work. To find out, you'll need to go to your LBS and get 2-2.5mm axel spacers (one for each side), so at least the hub is snug between your dropouts. Problem # 1 solved.

Now try the regular track nuts that come with the hub; if they do not seem to be threading on to the axel far enough, then try some smaller ones found at your local hardware store.

^your a fucking turd.....^

and to the original poster , they will work I have done this before , just beware of the Q factor (the left right width of your chainline) and try to keep the chainline as straight as possible

1.Adjusting your chainline with washers offsets your whole wheel, so it is no longer centered in the frame. If you do center it, then it is sitting in the dropouts crooked. If you adjust the chainline by altering the spacing on the axle you have to re-dish the wheel, and if you use both sides of the hub that going to throw the chainline on the other side way off.

2. Q Factor is the distance from one pedal to the other, aka the "tread".

3. Either squeeze the frame in with your hands, draw the dropouts together with a long bolt, or add a washer from the hardware store on each side, because even stainless steel washers cost less than washers cost at the LBS.
