Hi,
Are you after just shifters or shifter/brake combo?
If you are are after combo's and are running canti's I have a set of Shimano Alivio in silver and black.
Only used on the road - although used they are in good nick, shift well and have plenty of life in them. Made in the days when Shinamo only produced good gear and not the mass produced rubbish seen on many cheap end bikes of these days.
I can send photo's if needed.
Jules
