| Description | The 2011 Rocky Mountain Vertex 29 bike takes everything Rocky have learned over 30 years of manufacturing and racing bikes and created the same race winning performance in a 29" wheeled frame. Based on the winning Vertex platform but completely redesigned around the 29'er wheels. The evolution of Rocky Mountain's signature race hardtail, Vertex has already been piloted to World Cup victories by Geoff Kabush and Marie-Helene Premont. Vertex features Rocky Mountain's proven race geometry in a super light and stiff package. The Vertex alloy frame features a completely redesigned FORM tubeset, Shimano Direct Mount front derailleur mount, and BB92 bottom bracket shell. Alloy ST3 Geometry Mountain's tried and true sloping top tube geometry gives the riders ample standover height and a short wheelbase for nimble handling in technical terrian. Custom FORM Tubes New custom S-bend seatstays that are circular at the seat tube junction and flare to a rectangular shape at the dtopout. Circular shaped tubes are best when strength is required in all planes and rectangular tube shapes at the dropouts are best for fatigue strength. Larger Tube Junction By using a BB92 BB shell, Rocky are able to increase the size of the down tube/ seat tube junction, which increases stiffness without adding weight. Similarly, the new larger diameter head tube on the Vertex allows for larger junctions with the top and down tubes, further increasing stiffness and strength.
