Trek's strongest, lightest carbon yet
OCLV Carbon is Trek’s patented carbon fibre process, the result of more than 25 years of experience building the world’s finest carbon fibre bicycles in Waterloo, Wisconsin, USA. Experience matters, especially when working with a material that holds seemingly endless possibilities but presents such unique challenges as carbon fibre. To understand the best technology, you have to build it, and Trek have been doing just that since 1991.
Why OCLV Carbon?
A well-built carbon frame dramatically reduces weight compared to metallic materials, while maintaining the strength and stiffness that high performance bicycles and their riders demand. This is where Trek’s pioneered and patented OCLV Carbon—an acronym for Optimum Compaction Low Void—process comes in. OCLV Carbon frames begin with the best materials available. Utilising defence-grade carbon restricted from exportation outside the United States, Trek has spent countless development hours perfecting the construction of a variety of weights and types of carbon (cloth, unidirectional, etc.). The OCLV process is best explained when broken down into two parts:
Optimum Compaction: Carbon is layered into a series of plies compacted to the ideal fibre-resin ratio. The process starts with cutting carbon fibre from large sheets to a specific shape which is then placed into a mould. A combination of heat and pressure then compresses the sheets of carbon into a carbon lug. This combination of heat and pressure is OCLV’s most essential and closely guarded equation.
Low Void: Voids are the spaces that exist between the layers of carbon fibre that comprise a component or frame. Minimising these voids is the primary goal of quality carbon engineering, as more voids translates to reduced strength and durability of the composite material. OCLV Carbon exceeds aerospace standards regarding the number of voids in its material.
In addition to sizeable reductions in weight, the largest advantage of carbon fibre frames over another material are the limitless shapes that the material can be moulded into. Different shapes exhibit different strength, stiffness and aerodynamic properties.
Trek utilises Finite Element Analysis, a comprehensive software simulation toolkit, to tell us exactly how different shapes will respond to different riders and riding surfaces. We utilise proven theories of fluid mechanics through Computational Fluid Dynamics in order to explore the aerodynamic properties of various designs. Our bikes are conceived with computer-generated designs, fluid-dynamically assessed and finite analysed, and the resulting shapes appear seamlessly machine-made. At the end of the day, these complex scientific investigations are applied in a hands-on, ground-up process that combines multiple moulds with a variety of carbon materials to result in a magnificently engineered and largely hand-built product.
Mountain biking is about pushing the limit of where your bike can take you. Riding on every conceivable surface in hostile conditions takes a toll on any material. To develop OCLV Mountain, Trek’s engineers developed a methodology borrowed from the aerospace industry to ensure their frames were up to the challenge: Retained Strength. The philosophy is simple and based around the single question of how durable a frame remains following impact. By employing different composite materials in unique layups specifically in typical high damage areas, Trek’s engineers have created frames that now retain their ability to bear load after an impact surpassing even their aluminium counterparts.
Taking durability to another level, Trek’s development team created Carbon Armor, a highly refined elastomeric designed to slow down and spread the distribution of a sharp impact to the frame. Carbon Armor essentially decreases the immediate impact of a rough hit the frame feels, leaving you feeling more confident than ever to go after that next drop.
Built to last
Trek builds bikes to last and they stand behind every one that bears their name. Just as the first Trek hand-welded over forty years ago in a red barn, their first full carbon frame is still under warranty. All OCLV Carbon bicycles come with a limited lifetime warranty, because Trek believe that more people riding bikes is in everybody’s best interest.
