I'm a noob and I hear a lot names and model numbers thrown around with Shimano. Can someone explain their names and levels? I know deore is Midlevel and Ultegra is the best (i believe)
Also, When a Walmart bike has Shimano, does that mean its decent quality or do they also have a "junk" line for cheap bikes?
My trek 7500 has Deore lx group I'm assuming that means everything is mid-level decent parts.
