I've heard that every 3 years Shimano upgrades their component groups & the lower end groups basically inherit the technology from the higher end stuff.
ie: 2008 105 is equivalent to 2011 Tiagra.
I've used both (2008)105,& Tiagra(2011) on CX bikes,I prefer the 105 much better.
IMO the 105 feels smoother when I shift,Tiagra is clunky sometimes.
Could it be adjustment,probably.
I also like the finish of the 105 over the Tiagra.
Why hasn't anyone mentioned Dura Ace 7800/7900?
I thought we we talking about "high end"?

The rear wheel isn't hooked up in this video, but you get the idea.
The cable tension and more importantly, the resistance, needs to be right in order to be able to do this.
If you've got tight bends, bad cables, etc...you won't get that last click.
Starting at the smallest cog, it'll do 2 shifts on the first full sweep and then 3 on every one after that. I have 2 bikes with 6700 that will do it. My buddy's bike with 105 5700 will also do it.
That said, my 2nd bike with 6700 could initially do only 2 on a full sweep. It's an SL3 Roubaix with internal cable routing. Once I got everything dialed in, it now does 3 per sweep.
The earlier stuff is not as picky. It will do 3 with crap cables, bends, etc...though they didn't run the cables under the bar tape then (a big source of friction in a lot cases).

That would sprain my wrist. I would prefer one at a time with a teeny throw, but that's why there's vanilla and chocolate.
