One set sold a while back for $6 plus shipping. Several other sets have sold recently for $10. Are you using too many search words?
There is a set of 105s right now, with only one bid ($5). I hate to ruin it for that bidder.
On the OPs topic, it shouldn't work, but right now, I have Suntour 7 speed DT shifters, running a Suntour Superbe Pro 7 speed RD, with a seven speed Shimano freewheel, and KMC Z50 chain.
Tricky part with Cannondale is they usually use a flat adapter plate, whereas most bikes used curved ones. I have picked up flat adapter plates out of the LBS old parts bin.
If I am not mistaken, all Shimano DT 7sp SIS shifters are interchangeable, except Dura Ace. I'm sure I have a few in my bin.
Are these the shifters being discussed? They work fine with the Shimano Deore derailleur and 7 speed Shimano cassette pictured.
From the earlier discussion and data-points, I would assume that your Command Shifters are a 6-speed version, and that the detent-less shift goes out past the shifter's original hi gear position, to your smallest 7s cog.
As such, it should work perfectly with no need for cable-anchoring tricks or cassette re-spacing.
Well, at some point in the distant past, it looks like one of the four prongs on the freewheel was broken during a removal attempt. I assume I must be the guilty party (I'm the original owner, and I think I'm the only person who ever did any work on it), but I have no recollection of the attempt.
Anyway, with a proper 4-prong tool, the shop made a removal attempt this week, and another prong broke off. So, I guess that freewheel is staying on this wheel forever.
So I am still searching for a good way to lower the lowest gear ratios with a Plan B or Plan C. I'll start another thread to discuss options.
Thanks the input, everyone.
Since this thread popped up again- not that it's in the original premise- I was surprised by this:
I have a 1986 Schwinn Voyageur, I had acquired an Avocet wheelset with a 5 Speed Suntour Winner FW- something like 14-34.
When I was building it for myself, I put on a set of Suntour XC Comp derailleurs.
Since I'm building it to sell it- I put on some 6sp DuraAce 7401 shifters and immediately set it to friction- because I knew it wouldn't index.
Last week I had it on the stand and just for giggles, I set it to SIS- and it indexes PERFECTLY.
