Czechloslovakian 5-Speed Freewheel

Anyone run one of these things on a bike they own? All it says is " Made in Czechloslovakia Velo "

I'm going to swap out the current freewheel on an old Cannondale mountain bike for something more road ratioed

IIRC the Velo badge was one of several under the umbrella of Motokov Praha (export group) back in pre-1989 times. Do not know if it continues on today.

For an exploration of Czech cycles and fittings you may wish to explore here:

Pedaled a tour through Prague, 91, not long before the Slovak /Czech dissolution into 2 states ,
not long after the Warsaw pact dissolved, either..

Cannondale bought hubs.... etc. wheels may not be original .. I have to guess that they're British thread...

good luck..

Hi, Juvela posted the same example in question. I have that old Cannondale SM600 I picked up last December. It's wide range freewheel isn't necessary here on the prairie so I thought to swap out with another (like that old Czech). There's a Czech one just like it at the local community bike shop for grabs. I'm not set on obtaining it and would fit the Cannondale with whatever works just so long as it's economical (like the Czech one is). There is almost always a modern solution available out there in parts but most times at multiples what I paid for the whole bike. Another thing, is if the Czech requires a special removal tool then I'll just leave it there.

That must've been a cool ride. No shortage of top quality beer there after a day stomping pedals. Birthplace of Pilsener, right?

One common snag one encounters on fitting a used multi-cog gear block is tooth wear on the small, and possibly next to smallest, cog. This gives rise to skipping under pedal load. There is a measure of cog interchangeability amongst brands but it is limited. The later editions of the Sutherland workshop manuals have charts covering this. The Velo brand may not be covered in these tables.

From its outward appearance it looks like it may be similar to Regina.
