No, but I've had sufficient success just keeping an eye out for old lightly used FWs. I'm pretty well stocked up on 5 and 6 speed units. Ex: Saturday at the transfer station I saw a POS mtn bike. The R wheel was removed so I grabbed it. 6 speed Falcon FW, 14-28. I took it home and removed the FW. I was surprised at the quality but not the wear. None. It's actually pretty rare to find a badly worn FW as most bike were just ridden around the block a bit all those years then stashed away then thrown away.

I made a 'tribute' Roholf sprocket checker and I know how to use it, know the feel of good vs worn. This Falcon was just fine. Bit of rust but unused. It's not ultra spaced but will serve on my Voyageur if ever needed. I don't worry about buying ugly new FWs.
