Bura SL Frameset 2013
Excellent price on a sub 800-gram frame in brand new condition. Limited quantity available.
The Neilpryde Bura SL is the frameset of choice for the United Healthcare professional cycling team because of its ultra-lightweight 780 gram frame weight combined with race-winning stiffness. The rear triangle incorporates ultra-thin seat stays to tune the ride for the perfect balance between power transfer and compliance.
Exoskeleton technology incorporates carbon fiber ribs and gussets in strategic locations such as the top tube/head tube junction as well as the top tube/seat tube junction for optimum power transfer and riding performance. Developed initially for the Diablo model, the Exoskeleton design has been further refined through finite element analysis and applied on the Bura SL.
Other cutting edge technology employed includes one-piece stays and PU molding. A stiffer, lighter and more responsive bike can be built by reducing the number of joints in the construction of a frame, as extra bonds result in additional carbon required just to bond the numerous pieces together. Neilpryde developed a unique molding process for the rear triangle that enables the chain stays, rear dropout and part of the seat stays to be molded in one piece, reducing weight and creating a stronger, more durable rear triangle. Neilpryde engineers use a PU mandrel, instead of a traditional, silicone one, for more precise control of wall thickness and to prevent "fiber wash" - the misalignment of fibers during the molding process. Used in forming of the intricate head tube and seat tube joints and bottom bracket shell which are critical for ensuring precise handling and power transfer.
In case you are wondering, Neilpryde began manufacturing high-performance carbon fiber products in the late 1980s. They were launching the innovative Matrix system carbon fiber masts and booms to the windsurfing world, at a time when the Tour de France was being won by greats like LeMond, Delgado and Roche on steel frames. In the last 25 years, Neilpryde has been at the forefront of carbon technology and manufacturing processes collaborating with companies like BMW, allowing Neilpryde to develop lighter, more responsive, robust and durable record-breaking products and to foster new technologies and advance the performance of their bikes.
