Any good 7spd drivetrains out there?
I noticed that Jr's rear derailleur looks a bit twisted after our ride yesterday and there is definitely some added drag in the system. The bike (Cannondale Cujo 20) has a Shimano Tourney 6/7 speed derailleur with a 7 speed cassette. The tourney derailleurs are pretty inexpensive but they don't strike me as great quality either. Anything out there that is a bit better quality? I'm considering upgrading his twist shifter to trigger shifter also.
Any suggestions?
