FIXED FROM OLD FREEHUB
By Jussi Panula

Since quite a few people asked me about how I made this fixed system from an old freehub-system, I decided to do some sort of tech article: So here it is, step by step how I made it: First, I took out the freehub at the same time as when changing the hollow axle to bolt-model.

Then I drilled 3 holes through the freehub body, so that those holes went to the axle hole.

BUT then I LATER NOTICED: That the first freewheel (from early –90s) which I used, must have been little softer. I tried later with more recent model, which was too hard to drill, so I warmed it up with a gas-torch and then the drilling was possible.

Then I made the threads with a normal thread-tap, and shortened those 3 stainless bolts to exactly same length as the freehub body thickness, so these (the) bolt ends came very close to the axle-space. After that normal assembly, tighten bolts, assemble the freewheel to hub and axle into it's position...

The place for drillings was purely a guess, well I decided to drill holes as near as possible to inner side, and that seemed to be successful...

Why not use spacers? Well, because I used an early-90s -model freehub, it has threads outside for the 2 smallest cogs of 6-speed casette ;) so the rear cog on my hub is locked with a normal BB-locking ring inside and outside with standard casette lockring+2 spacers... With a newer model freewheel you will need more spacers...

And Why I did this? Well, it's not easy to find real “Track”-parts here in Finland, there are only a couple real (outside) velodromes in the whole country. The White-Eno hub is very expensive here (more than 200€),

and other hubs are difficult to find. I wanted to see if I can use only old parts for this project... It was a success ;)
