Yeah, I'm just trying to figure out when looking at bike A with Deore and B with Tiagra and C with 105 and D with Ultegra and E with whatever how to figure out what order they should go in for group quality level.
First you might want to decide what kind of cycling appeals to you, and look for the type of bicycle that best matches that kind of cycling.
Do you think mountain biking might be your thing? Or do you want a bicycle for commuting? Or touring? Or long distance cycling? Or road racing? Or ... what?
And within the category that you choose, what do you want to do with it?
