I am having problems with my Shimano RX 100 brifters. I recently alligned my rear derailer. I find that although shifting down gears is fine, as soon as I try to shift up a gear it skips all cogs and goes to the upper limit(smallest rear cog), set by the limit screw. Does anyone have any advice? I think it may be too much tension in the cable but am not sure.
Any help would be greatly appreciated thankyou.
