We know it’s not just about the weight but what you do with it, too. BURAsl was purely performance engineered for the highest stiffness to weight ratios and most efficient and direct power transfer. And this happened to result in 710 grams of raw desire. That is it: bare minimum paint – maximum performance. The only thing we piled on was the unflinching NEILPRYDE attitude, which weighs nothing.
BURAsl front triangle is made from NEILPRYDE C6.9 uni-directional carbon fibre, the highest modulus suitable for bikes, and incorporates our proprietary Exoskeleton technology, first developed for the award winning DIABLO. Additional layers of directional 3K carbon are carefully applied by hand in the bottom bracket and head tube to increase power transfer and steering accuracy, respectively. External carbon fibre ribs integrated in the key joints of the monocoque front triangle ensure the BURAsl frame responds immediately each time you step on the power and jump for the sprint.
Drawing on our 25-years of composites manufacturing experience, a new molding process was developed for forming the intricate head tube and seat tube joints, and bottom bracket. The result: significantly improved control over the frame wall thickness and elimination of fibre wash during molding in the areas critical for achieving the desired frame performance.
When engineering the rear triangle, a unique one-piece chain stay, drop out and seat stay mold was developed. This enabled the reduction in the number of bonds, while allowing for continuous strands of carbon fibre to be run through the rear triangle. Combining this unique design with the “chopstick” thin seat stays resulted in the perfect balance between power transfer and ride compliance. Carbon fibre front and rear drop outs, a PressFit 30 bottom bracket, and carbon headset cups further reduce the frame weight without sacrificing durability or performance.
BURAsl is available in two modules – either mechanical, compatible with external cable routing for the ultimate lightweight frame, or internal Di2 wiring for that ultra sleek look and dialed drive train shifting.
