How can I make a 120mm track hub work with 130mm spacing?
I have a set up 120mm track specific wheels that I would like to use to conver my brother's old Puch 6 speed. I haven't gotten his bike yet to measure, but is there some kind of way adapt the 120mm to a wider hub like 126mm or 130mm?

Add spacers between the cones & locknuts.
You might need a longer axle. |

I would take the wheel to a decent shop and ask them to sell you what you need.
They can also measure the axle and help you determine if you need a longer one. |

Where can I get these spacers? Ebay? Any name brands. Thanks:)

I did this with an axle that I bought at my LBS, works fine. You could also order one from Harris. http://sheldonbrown.com/harris/axles.html

"Spacer" in this case is just another way to say "washer".

He could probably pick them up at his local hardware store. He only needs 3mm on each side to space to 126mm and 5mm per side to space to 130mm. A regular flat washer per side should do it. If it's close (say 124 or 128 mm), the natural spring of the rear triangle will make up the slack.

If it's steel, you can always cold set it.

What does cold set mean?

Not recommended for aluminum frames. |
Reviving an old thread :)
Is it possible to use this AC track hub (120mm) on a 130mm wide frame? Hub: TRACK|REAR If so, do I need a bolt based axle as opposed to a quick release to fit the spacers? |
if that hub is attached with a couple of bolts, and it looks like it is, you could just slip a 5mm washer between the end of the hub axle and the dropout. one on each side. the bolts may be too short, so don't get your hopes up.
you might want to look at how the axle is assembled. it might offer a cleaner solution. |
Just search against my name for hub specs...
...you'll see plenty of write-ups on how to get the standard spec you need when converting a hub. =8-) |
