Hi,

I'm in the process of purchasing my first hybrid and I was wondering if anyone could explain to me the difference between the Shimano components and their importance? Is there really a big difference between Tourney, Altus, Acera, and Alivio? Does it make a big difference as to where they are used (ex. Shifters, Front/Rear Derailleur)? I'm a bit confused on the Shimano front. What should I be looking for?
