I have an old road bike, that I converted to a hybrid bike, I just use it for small tourings. Some time ago I changed the handlebar, the brake levers and the tires.
Recently the derailleur broke up, it was in bad shape and there's no way to repair it, so I just want to get a new one, also I would like to replace the shifters, as they are the old ones that are on the frame, and put triggers like an MTB.
The bike has a 6 speed cassette, I was thinking in a cheap Shimano Tourney derailleur but I can't happen to find trigger shifters of 6 speed on online stores. My idea would be to put a 7 speed shifter with just 6 speeds and someday change the cassette.
What you think? Would be possible to put a 7 speed cassette? Any other suggestions?
