ProBikes: Two sharp rides from the Giro

While cycling’s grand tours represent some of the best bike racing in the world, they also offer a lot of us a first-hand look at some of the best racing bikes in the world. I spent some time at this year’s Giro d’Italia and sorting through my files, I wanted to share a look at two bikes that really caught my eye in Italy last month. David Zabriskie’s Giro TT bike

While cycling’s grand tours represent some of the best bike racing in the world, they also offer a lot of us a first-hand look at some of the best racing bikes in the world.

I spent some time at this year’s Giro d’Italia and sorting through my files, I wanted to share a look at two bikes that really caught my eye in Italy last month.

David Zabriskie’s Giro TT bike

The only rider to use Shimano electronic in every stage of the Giro, DZ’s bike is special. Due to inadequate length of the wiring harness for internal routing, the wiring is taped to the outside. This DA SL frame has the standard team paint and graphics, since Zabriskie’s “Captain America” TT bike, with special National Champion paint and graphics, blew off of his roof rack and that frame was completely destroyed.

By working with the Garmin-Slipstream team, Felt produced the special lay-up for this bike that is now also used for 2009 production DA bikes and frames.

Gilberto Simoni’s Giro road bike

The Gibo Simoni replica 2009 frame employs a new Dedacciai custom carbon tubeset and is a prototype of a frame that will become part of the 2010 range of the storied house of Guerciotti.

Guerciotti makes use of Gilberto Simoni whose experience, knowledge and ideas make him the perfect product tester. This frame improves on the lightness and stiffness of the Gibo Simoni replica 2008 built last year for the two-time Giro d’Italia champion.

With this new carbon tubeset (it is not a monocoque frame but instead uses separate tubes joined with wrapped carbon technology – making it possible to make any size standard/sloping/custom), Guerciotti claims a weight of 995 grams, including the integrated seatpost. To increase the stiffness of front end, Guerciotti uses a tapered head tube to fit the 1-1/8 – 1-1/2-inch steerer of the new RS Carbon monocoque fork. Custom translucent metallic blue/silver paint makes Gibo’s bike immediately recognizable.

Wrapped carbon technology means builders can make small changes in frame sizes.
