Shimano's Ultegra Di2 is truly exciting because it combines the operational joy of Dura-Ace electronic shifting with a reasonable cost. We have it here on the Orbea Orca Bronze/Shimano Ultegra Di2 Complete Bike. What you'll get is a surprising level of performance. The frameset is made for city limit sprints and long easy rides alike and the Di2 gives you shifting precision and consistency like you've never experienced before. The Orca Bronze frame and fork are made with Orbea's Bronze grade carbon and it's a blend of intermediate modulus fibers that have a touch more elasticity than the higher modulus fibers in the Gold and Silver Orcas. That the intermediate fibers also create a more durable frame is an added bonus for those looking at their first carbon fiber bicycle. The real benefit of carbon fiber is the silky smooth ride. It absorbs high frequency vibrations from coarse road surfaces better than aluminum or steel frames.Like the Gold and Silver Orbea molds the Orca Bronze frame and fork as a monocoque. Each of these is a homogenous structure with fibers running continuously along the length of the tubes and through the intersections. This increases the total strength of the bike along with the durability. There are a few structural differences that separate the Orca Bronze. It uses alloy dropouts and the seat tube here is round where the Gold and Silver have a more sculpted aero shape. This allows the use of a less expensive standard round seatpost and conventional clamp assembly.Otherwise the front triangle uses the same planar styling as the other Orca models. And the tube shaping isn't all about good looks. The angular tube shapes and sometimes pronounced edges are the result of FEA (finite element analysis) and their intent to create resistance to flex in critical areas like the bottom bracket seat tube and head tube junction. Orbea uses what they term as SSN (size specific nerve) technology to produce frames that offer the same comfort and per...
There are tons of jackets on the market that keep precipitation from getting to your skin but few jackets pay as much attention to pulling moisture and perspiration from the inside out as the Marmot Interfuse Jacket. This fully waterproof highly breathable technical shell is lined with Marmot's proprietary DriClime Mesh which is specifically designed to move moisture away from your body and out to the surface of the jacket where it can evaporate quickly. The Interfuse also features Angel Wing movement and Extra Stretch Performance to provide an unlimited range of motion and make the jacket ideal for skiing hiking and even ice-climbing.
