I am helping fix up an old bike (1987 Trek EX560 steel, 126mm dropouts)
with minimum $$. The bike has a Shimano 105 (FH-1050) rear hub with a
Uniglide 6-speed cassette. The rear derailer is a Shimano 105 (RD-1051).
Can I upgrade to a 7-speed cassette? Can I install Shimano 7-speed SIS
bar-end shifters even the cassette can't be upgraded? If not, will a 7-
speed indexed downtube shifter work? The current setup has a friction
downtube shifter that I would like to replace.
BTW, I found an obscure web site that seemed to indicate that the FH-1050
is 6-speed only, and that the FH-1051 model is able to have 6 or 7 speeds.

Any ideas?
