Do you need indexing? Friction works well on a 7spd cassette, and you can mix all sorts of things together for that to work.
If you are set on trying to find the now rare period correct Shimano 7spd barcons, I can sell you a new in the box set for $120 shipped. If the rear wheel is a shimano cassette free hub, possibly the most interesting thing to do is put 8 cogs from a 9speed cassette on the 7spd freehub and use 9s barcons. The 9 speed chain you will want for this should work with your current crank and derailleurs. This is called 8 of 9 on 7 if you google it. My strategy to do that was pick a wide range cassette like a SRAM PG950 11-32 and remove the large 32 to make it a 11-28. However since it is likely that your 7spd rear hub will not accept a 11t cog (a few exceptions are STX and RSX) you could also replace the first 2 cogs (11,12 or 11,13) with a single12t or 13t first position cog instead. Riv has stocked a shimano 12-36 on the Joe. I think this is the Shimano HG400, but I'm not sure. That would make a 12-32 by removing only the big cog. Obviously buying a 9s cassette, shifter, and chain to do this is also not cheap, so maybe only makes sense if the chain and cassette needed to be replaced anyway. Note: the SRAM PG950 can be completely dissembled with a small metric allen key. Some Shimano cassettes can be dissembled by drilling out the rivets, but some versions of cassettes from all brands do not have individual cogs. Usually the higher end cassettes have an aluminum carrier and the lowest end shimanos have the largest cogs bolted to the next cog over and don't touch the cassette body. Maybe you could cut them off, but its easier to deal with cassettes that can be disassembled to 9 individual cogs. -Dave J Virginia On Saturday, August 13, 2016 at 1:50:20 AM UTC-4, twowheeledtexan wrote: > > Anyone have any bar end shifters that work with 7 speed Shimano?
