Shimano 105 missing downshifts.
I have 9 spd 105, and occassionally, when I go to down shift, usually onto the biggest cogs, the lever moves with absolutely no resistance, and of course, no shift. I let it return and shift again and it works. I cleaned it out with solvent and haven't been able to check it yet, but if its not fixed, any ideas?
