Is this Shimano Ultegra 2005?
The Bike is a Kona Kona Deluxe 2005 model. (Pic from kona.dk)

Thats the 05 Ultegra, 10sp, hollowtech 2 cranks and the shifters in that ugly position.

In that photo the cranks look like a cross between 2004 DA and the old 1996 low profile DA (one of the best looking cranks ever).

The shifters look like a bulky version of Dura Ace 10spd or a cross between old and new Dura Ace.

There is also a slight change in the brake caliper design - More like it's predecessor, DA.

The R derailleur looks very similar to it's previous one.

Other than that, the rear triangle on that bike is quite nice.

It's the full 2005 Ultegra.
