i just got my custom carbon evolo from guru about a week ago. only have two rides on it so far (bad weather and moving don't leave a whole lot of time for riding), but it is a wonderful bike. the frame has a 74.5 degree seat tube angle with approx. a 55cm tt. the head tube is tall also, so that the frame can accommodate my somewhat short torso compared to my arms and legs. the frame is extremely stiff, but still extremely comfortable. before ordering this bike i rode a madone (number escapes me, but it was one of the top models), and look 585, and an orbea orca. they were all very nice rides in their own way, and i probably liked the 585 the best. the guru does not feel as light while riding it as the 585 did, but it is. it has absolutely no flex at all, and the bottom bracket can not be moved. it is a very smooth bike, and really makes the road disappear. The bike it obviously rather short, and it really turns like a race car. it definitely does not feel as tall as it is, and the alpha-q fork that they have chosen to pair it with seems like it was the right choice for this frame. i am 6'1", 163 lbs., chaser/sprinter. The build:
guru evolo custom carbon, white/red
easton ec 90 zero setback
fizik arione red/white aqua-sapone team edition
fsa sl-k handlebar
deda zero100 stem, black.
rolf vector pro tubulars (just cracked the rear hub flange, so they are out of commission for a bit).
bontrager xxx-lite carbon tubular team edition
look carbon pedals
with the bontragers, cages, and full saddle bag, the bike weighs 7.25.
the moral of the story - guru makes a very nice ride. i have seen their ti work also, and the welds are stunning. if you are looking for a custom carbon ride, i am sure that you could do a lot worse than these guys. they make their own everything - tubes and joints - and from my short experience, do a very good job of it all.
