Mark Vanek of Marin Bikes goes over the all new 2009 Stelvio in detail with us. It's the next generation of carbon bike from Marin Bikes, a major change from their previous CX7. The new Stelvio features a full monocoque frame structure including a box section bottom bracket for increased stiffness. New profile chain stays add to rider pedal input, resulting in a more active feeling bike. Seat stays are a little different from the previous Marin models as well, they've gone with a split seat stay design, which allowed Marin to fine tune the frame to improve ride quality. The bike is still in development with regional riders as well as a few European riders testing the bike, with a few expected tweaks before final production begins, it won't be long before you can check one out at your local shop.
