Features- Carbon frames are generally manufactured as a "monocoque" structure. This means the entire frame, or significant parts anyway (front triangle, or rear triangle) are molded as a single piece. The bladders that are used to pressurize the frame during molding are difficult to control and may result in additional resin left inside the frame. While this can ensure good continuity of the carbon fibers through that part of the mold, all monocoque frames still require that frame parts be glued together. Marin employs this manufacturing technique where it makes sense, but in the road category, we primarily use T3 construction, also know as "tube to tube". In this technology, each frame tube is individually molded, which allows us to precisely control the wall thickness of each tube, resulting in ride tuning perfection. Then, each tube is laid into a fixture that positions them to precisely the angles required for that frame, where they are then bonded into place, and reinforced with an additional lay up of carbon, before going into the heating ovens. This extra care results in absolute minimum weight, perfected ride feel, and a bike that you won't want to climb off of. - An interchangeable cable management system for 2014 carbon hardtail, cyclocross and road frames. - Formed seat tube assemblies found on carbon Marin Endurance Fit & Pro Fit road bikes and Cyclocross bikes to maximize energy transfer and rider comfort. - Press Fit 30 was developed by SRAM as a variation of the BB30 standard. BB30 required that bike frames be precisely machined to allow bearings to be directly pressed into the bottom bracket shell, in order to accept crank sets with a 30mm diameter aluminum spindle (hence the name BB30). - The Rapid Vibration Suppression system is our tuned seatstay forming process designed to reduce shock transmission between the rider and rough road surfaces. - Marin uses tapered forks that have a 1.5" lower diameter, but then taper to a 1-1/8" upper diameter. This reduces weight, but keeps very high strength where it's needed, at the base of the steerer tube, where it meets the fork crown. - Competition-based geometry that blends classic European road racing geometry with a more contemporary riding position and frame dimensions that focuses on agility and responsiveness.
