Shimano

I have Shimano Sora and my brother has Shimano 105's..... Is there a huge difference?

Yes. In weight as well as tolerances, which leads to better performance.

What Hack said. However, I understand that Shimano made some improvements to the Sora components for 2012. The thumb shifter is no more, although I really liked it on my Defy, and the derailleurs are a bit smoother when shifting. I haven't ridden a bike with the new Sora line, but this is what the guys at the LBS are saying.

Ask StormStrikes he went from Sora to S105.

For what it's worth, neither will make you a better rider.

All you get is crisper, more reliable shifting. Especially under load.

I am also looking to upgrade from Sora to 105. I want to swap both the shifters and the rear derailleur.

For those who don't care as much for weight or performance gains, and only want to get rid of the thumb shifters, there is also Shimano Tiagra. I swapped the shifters on my Trek 1.2 from Sora shifters to Tiagra so I could get the lever shifters. I have no complaints about those, and they cost less than 105.

Sometimes a headwind is really a tailwind, and sometimes a tailwind is really a headwind, to your development. Deep Thoughts.
