The angularity of the Orbea Orca Silver is unmistakable, and it?s a striking quality that leaves you with a lasting impression. At first glance, it looks almost brutish, like its planar design is there to skew its radar signature at some terrifying top speed. It shares this same overall shape with the more expensive Orca Gold, though this one makes use of a materials mix that leaves all the performance out on the road without producing such a lasting effect on your wallet.While the Orca has been around for a good number of years, its recent re-design has upped the ante considerably. Where the older bike used more traditional rounded tube shapes, this one nearly ventures into art deco. However, the tube shaping isn?t all about good looks. Orbea uses what they term as SSN (size specific nerve) technology to produce frames that offer the same comfort and performance characteristics across the size range. More specifically, each frame size has specific carbon lay-ups and tube dimensions. This way, a 125lb five foot seven mountain climber doesn?t have to suffer the otherworldly stiffness that would be necessary on a bike built for a 180lb six foot four classics rider. Otherwise, the angular tube shapes and sometimes pronounced edges are the result of FEA (finite element analysis) and the intent to create resistance to flex in critical areas like the bottom bracket, seat tube, and head tube junction.That said, Orbea uses some particular shaping in the seat stays and fork legs of the Orca Silver and Gold models to absorb road vibration. They call it Attraction, and you won?t find it on the Orca Bronze. Take a close look at the abrupt bends above the full-carbon dropouts. Their shaping allows some shear movement between the long axes of the straight segments. While this improves comfort over coarse road surfaces, it has no effect on the stiffness of the rear triangle with regards to power transfer. Make no mistake, the Orca Silver leaps when you punch on the pedals. Orbea molds the Orca Silver frame and fork as a monocoque. Each of these is a homogenous structure without bonded joints where failures, either structural or cosmetic, can occur. With fibers running continuously along the length of the tubes and through the intersections, the total strength of the bike is increased along with the durability. The Orca Silver is made with Orbea?s Silver grade, high modulus carbon fiber. The difference between this model and the Orca Gold is easily quantifiable in numerical terms -- for another thousand dollars you can save 130 grams and get an admittedly exquisite clear coated carbon weave finish. Out on the road, you?d be hard pressed to discern the difference. Ultimately, the gold is a bit stiffer as well as being lighter. It?s not a stretch to think of the Orca Silver as the Ultegra of the Orca line. With performance nearly indistinguishable from the top of the line model, why pay more?Like its more expensive sibling, the Orca Silver uses a BB30 bottom br
