Odd. I've been lead to believe (by members of this group) that seven and eight were compatible. ie.
an eight speed shifter will work on a seven speed cassette.
Of course but that wasn't they guy's question, he wanted to know if you could convert a Sora 7s
shifter to 8s, which you cannot..
Nor can you convert any STI to another speed...some are compatible and there are some
'workarounds'(9s shifters and 8s casettes, via spacers, etc) but no lever conversion is possble.

shifter, no.
But put that 8s casette on the bike and use a Sora 7s shifter and you will not get all the cogs.
