Mid 90's Trek 720 Multi Track upgrade questions
I inherited a 1994 Trek 720 Multitrack and I'm pretty sure it has low quality drive train group. Here is what is all listed from Bike Pedia:
Component Group Shimano Altus C50 / GripShift
Brakeset Cold-forged alloy w/Shimano Tourney levers brakes, levers
Shift Levers Grip Shift SRT-300i
Front Derailleur Shimano CT50 GS
Rear Derailleur Shimano Alivio GS
Crankset Shimano CT-50, 28/38/48 teeth
Is it worth it to upgrade this to a more reliable system? Plus I think I'd rather have rapid fire type of shifter instead of grip shifter.
Also does anyone have any suggestions on what type of group I should be looking at? Also on a Hybrid do they use Mountain bike components or do they have their own class?
Thanks for any tips!
