Velocite Geos – Light, Nimble and Versatile Full Carbon Road Frame

 

2011 Taipei Cycle Show – March 16th, 2011

Velocite Geos is the newest carbon road frame from Velocite that meets the needs of riders seeking a very light bike that performs at the highest level.

The Geos development started over 2 years ago, code named ULRF – Ultra Light Road Frame. The prototype live testing program commenced 8 months ago across 4 continents covering many rider types and terrains. During the development process, 3 different geometries and 3 carbon fiber layups were tested until Velocite arrived at the current design.

 

Weighing just 996g for a size L frame, the Velocite Geos enters the market positioned squarely among other top of the range lightweight frames. What differentiates it from the competition is the use of a full carbon BB30 shell and an asymmetric 1.5” head tube that takes advantage of carbon fiber bearing races. These features serve to reduce the frame’s weight and increase its stiffness at the mechanical contact points.

Velocite Geos is also differentiated by its use of a sloping design and a compact rear triangle.

“Velocite’s promise is to deliver the maximum stiffness products at the minimum weight, thus our stiffness targets are very high. The only way that we could make a lightweight frame that meets our high stiffness targets was to adopt a design that serves to minimize the tube lengths”, said Victor Major, CEO of Velocite.

“Unlike the other lightweight frames in the market that make use of very thin and long seat stays and increased frame bulk at the bottom bracket, we decided to aim for a frame that delivers higher stiffness. It is often assumed that increasing the frame’s dimensions and bulk at the bottom bracket is sufficient to deliver a stiff frame. This is not entirely correct. While applying force through the crank set, the frame does not bend at the bottom bracket, it bends around the bottom bracket, thus just making the bottom bracket area wider, or larger will mainly just give the appearance of stiffness.” also said Major.

Velocite Geos utilizes wider than usual seat stays and over sized chain stays to deliver a stiff rear triangle. It also features a multi shaped down tube with some sections 60mm in profile. These elements serve to stabilize and stiffen the frame during high exertion efforts and high speed descents. This was validated during the live testing program, where test riders reported that the Velocite Geos is a very good frame for climbing.

Front end stability is assured through the use of an asymmetric 1.5” head tube and the Velocite Bora S full carbon monocoque fork. Additionally, in response to the live testing feedback, Velocite adjusted the carbon fiber layup at the head tube junction increasing the frame’s weight by 50g, but delivering class leading font triangle stiffness.

The Geos also delivers a comfortable ride, especially over larger irregularities. This is in part due to the standard full carbon seat post that is included with the frame, the Velocite TLCS31 (167g). Due to the frame’s sloping geometry, most of the seat post is exposed, increasing its vibration dampening abilities.

Velocite Geos will start shipping by April 2011 and is priced at US$1799 for the frame set that includes the Bora S fork, headset, TLCS31 seat post and a seat post clamp. A 6.05 kg complete bike built with SRAM Force, 3T and Velocite components, and Velocite 38/38T tubular wheels with Vittoria Corsa CX tires is US$ 4999.
