[RBW] Re: WTB: 7 spd bar end shifters

[twowheeledtexan]

Thanks for the info. I think I'll try the 8 of 9. Yes, I'd like indexed 
shifting, currently have Silver shifters but I prefer the indexing.

I'm shifting 7 with *Riv bar end pods* 
 and my old Zeus downtube levers 
- works great



Rivendell also sells* silver shifters in bar end pods 
* and these are very good 
ratcheted shifters.

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.
