What difference did/do you notice?
I was going to get the 105, but knowing myself I'd probably hold onto it for a year or two and end up getting the Ultegra eventually anyways...but now I don't know!
For me the differences is in the RD and Shifters. The Shifters on 105 feel a bit rougher in finish and the shifts are precise but a bit rough. I've had 5 bikes with 105 and all were tuned up.
Ultegra on the other hand... the shifters feel a bit more solid and the shifts are like butter no matter. It's a very smooth transition but I can feel that very slight difference.
