I want to have a new road bike, but I'll build it myself by buying separated parts and putting it all together. I was wondering about the quality of components, and how better the top brands are to the bottom ones.
Ok, let me put this way: shimano has pretty good parts from all it's line up, right? But besides weight, what is the difference between, let's say, the 2200, the Sora and Ultrega? Does the Ultrega group lasts a lot longer than the 2200? Is it more reliable? Will the 2200 skip gears? Will it break sooner or lose the tuning faster?
Does a regular person notice some difference or it's more a pro thing?
The reason I ask is that my old mountain bike have the Alivio group, which still works beautifully after 10 years of use, and after riding some bikes with XTR and Dura Ace I couldn't feel much difference. Sure, the top ones were new and all, but the gears still where changing as they should and the wheels rolling as the needed to.
