and old man i buy parts from has several freewheels with the largest cog being a skiptooth, are these hard to find and are they worth buying? thanks

Are they 3-spline or thread-on?

Are you sure they're freewheels? Are they single speed?

not sure about the threaded or splined but they have about 5-6 cogs on them.he told me that they thought the skiptooth on the larger cog made for smoother shifting onto it. they are old so they may be threaded

theres actually one on ebay, says its a schwinn, goes for about 40 bucks, so it might be worth getting them. i can probably get them for about 2-3 bucks apiece.

Sounds like you're talking about Shimano 5 speed freewheels where the largest two cogs are skip tooth. Are they gold/bronze colored?

I have just acquired this as well off an old Schwinn sports tourer.

It was not my bike, we were fixing it up for a friend to ride and i noticed the skip tooth freewheel but removed it since it thought it was funny and he needed a proper 6 speed freewheel.

Not trying to hijack this thread but more info please!

Not to sure on specifics I was there to buy some spokes and noticed them hanging from the rafters. He's going out of business and called me to see if there was anything I wanted before he sold anything to the public.

I've seen an early Shimano 5-speed freewheel, 14-34, two largest are skiptooth. The only problem is that it takes the small early Shimano removal tool. Other than that it works fine.

Have one made by shimano on the Moto.Very smooth shifting.

thats it.thanks

This is on EBay for $37.



Not likely selling, but gives you an idea.

And who made the "Schwinn Approved" Model J, or Model F, or Model G? Made in Japan, but no other maker info. I have a couple. Has the Regina type spline.

$37 for a freewheel missing half its teeth Good Grief!!

Skip-tooth (1" pitch on the largest two cogs) freewheels were standard on the '73-'76 Schwinn World Voyageur/Voyageur II and '71-'75 Sports Tourer. That particular one happens to be a "Model J" (made in Japan by Shimano) from a '73-'76 World Voyageur/Voyageur II, which came with 14-17-21-26-32T cogs. It originally had a gold anodized finish, however I believe the seller treated this specific unit to an oxylic acid bath that unfortunately ate the gold finish off along with any rust. This version has round lightening holes in the larger cogs:



I've observed that '75 and later versions of these freewheel clusters came with much larger "Shimano triangular" shaped cutouts in the larger cogs, which made the entire unit about 2 oz. lighter overall.

The '71-'75 Sports Tourer came with a similar "Model J" (Shimano) skip-tooth freewheel and cluster, however it had wider range 14-17-22-28-34T cogs with what seems to be a black phosphate coating along with a modified freewheel having a lip for a snap ring to attach an integral high-gear chain guard (standard on most Schwinn freewheels at the time). Here's a picture of one on a '75 Sports Tourer showing the larger lightening holes and high-gear chain guard:

Not worth buying. Those things are boat anchors.
