Cruisin' on my Bluebird
On closer viewing, I'm now of the opinion that the freewheel teeth on the middle and high gears may actually be designed specifically for this system.@dnc1 , glad you were able to get out and give it a good ride. Was the gearing fairly reasonable? It looks like a 46t-48t front; I didn't really look at the rear sizes. I did notice that the freewheel teeth appeared rather "worn" on the 2 smaller cogs. Do you know if that is a designed tooth specifically for these shifting systems, or is it just decades of wear from use? I was wondering before your ride post if that might have affected gear shifting above and beyond the shifting system itself.
While perusing European sales sites I stumbled across an old "Cambio Corsa" frame set for $125 USD (decals were gone so unidentified brand). All I would need to do is spend about $800-$1000 to build it up with the shifting system (I saw the spoke guard on sale recently for $175); that wouldn't even include the wheels or brakes!
Someone else has suggested that this may be the case for some of the freewheels used with these systems and I am curious to know more.
Here is a close up of the freewheel.....
...As you can see, from the cleaned up high gear wheel, it does look more designed, than worn.
Does anyone recognise the manufacturer?
I would be interested to see close up photos of any of your examples @Freqman1 to see if there are any similarities.
