The new Orbea Occam is designed for mountain bike lovers. Developed with Advanced Dynamics technology, this new frame provides 123 mm of travel for the purest Trail and All Mountain adventures. We have designed it in two materials we have honed to perfection: Carbon (Orbea Monocoque Silver) and Hydro-formed Aluminum (Orbea Hydro).
Efficient: We put in your hands a bike with optimum performance in Trail and All Mountain terrain. A machine that allows you to pedal with minimum suspension interference.
Dynamic: The work done by Advanced Dynamics software has resulted in a bike with a high absorption capacity and optimum performance whatever the terrain. In other words, you have at hand a fast, stable, comfortable bike… A bike that will take you anywhere and that will motivate you to take full advantage of the mountain!
Reliability: Trust is everything. Whatever the terrain, the Occam reassures the rider thanks to the Advanced Dynamics Technology: The wheels float over unevenness and respond to the terrain keeping traction on the most demanding climbs and the most complicated descents. This continuous contact is what enables you to go faster with greater confidence.
Lightweight: On both the Silver and the Hydro model, we have achieved the low frame weights that riders demand while keeping the durability that makes our bikes legendary. If you want an agile, manageable machine with nerve, that’s what Occam has to offer.
Advanced Dynamics
Advanced Dynamics is the fruit of a long process of reflection, analysis and research on dual suspension bikes. Until now, the technologies applied to these bikes were based on flat kinematic analysis plans and two dimensional diagrams. Orbea brings to the table a virtual analysis where all variables are taken into account: accelerations and relative speeds at each point of contact, suspension transfer on each type of terrain, rider weight, even tire size and pressure all studied for the first time. Advanced Dynamics is supported by unique software tools through which our engineers can obtain a very accurate vision about the behavior of the bike before it is built. By adding this information to real-world feedback obtained in tests with prototypes, Advanced Dynamics becomes the perfect tool for creating dual-suspension bikes.
Based on this knowledge we have created the most efficient 123 mm travel bike on the market. Careful pivot placement creates a machine that allows you to climb anywhere with minimum suspension interaction. Meticulous custom tuning of the FOX shocks has allowed us to optimize suspension sensitivity to the extreme.
The linkage we have designed for the new Occam, dubbed Diamond Link, controls the ratio curve established by the Advanced Dynamics System. The first part of the curve is tuned to increase leverage over the shock, giving the suspension enhanced sensitivity around the SAG position. We continue with a second slightly more progressive section which allows full shock travel while neutralizing the tendency of air shocks to wallow in mid-travel. The result is unlimited plush travel that rivals the feel of a coil shock at a much lower weight.
Orbea Monocoque Silver and Orbea Hydro-formed Tricone Aluminum
The new Orbea Occam is built in Silver Carbon and Hydro Aluminum. The Silver version is composed of a blend of high and mid-modulus carbon fiber to provide stiffness and high impact resistance. It is this precise combination of fibers which gives a maximum Young Modulus score and great durability, translating into a high performance bike which is robust enough to last.
The aluminium model is created in Hydroformed Orbea Tricone Aluminium, an extremely light material with impressive mechanical properties. It incorporates aluminium, silicon and magnesium and receives two thermal treatments at temperatures up to 565 º C. The tubing is manipulated by complex triple butting and hydroforming processes to provide minimum weight with high levels of reliability.
Concentric 9-12
Look at the rear of the bike. What do you see? Nothing? Look again. Now you see a pivot at the intersection of the chainstay and swing arm. This is one of the constructive solutions that we have worked for the new Occam: minimizing weight, providing stiffness and safety and facilitating the use of direct-mount disc brakes.
There are times in the cycling world that we endeavour to innovate to the extreme, when there are simple solutions that were invented over a century ago. This solution was patented more than 100 years ago and today is of great interest as it provides a long-existing solution to complex new suspension and braking issues. In addition, the unique interchangeable design of the Orbea C9-12 allows the use of both traditional hubs as well as super-rigid 12 mm through-axle hubs. (X12, 12×142, 142mm ….)
Innovative Trail Geometry
Advanced Dynamics and extensive testing have led us to an aggressive, nimble and progressive geometry. Under the assumptions of a revolutionary trail/all mountain bike, we had to design a versatile and efficient machine which was fun at the same time. A steep seat angle, slack head angle and ultra-short chainstays translate into an optimal pedalling position for climbing and reward the rider with maximum control and stability on every descent.
Seat Tube: 74’5 and 73’5 °: Whatever the climb, you´ll always pedal well. The 74’5 ° (with 120 mm fork) and the 73.5 ° (with a 140 mm fork) seat tube angle provide an optimum pedalling position, keeping rider weight centered and balanced.
Head tube: The new Orbea Occam will be available in 120mm and 140mm fork configurations. The first yields a head angle of 68’5 ° and the second reduces the head angle to 67’5 º. This option allows riders to set up the Occam for exactly the descending style they prefer.
420 mm chainstays: Have you read that right? Occam has the shortest chainstays of any trail bike on the market. This compact design provides a great handling machine that excels on tight, twisty trails.
Highway cable downtube: The Downtube Cable Highway cabling system is another solution that provides clean lines and simplicity for the new Occam. We have brought the cable through the upper part of the diagonal tube with which the interaction with the suspension is eliminated and as a consequence with the pedalling.
THT: Just like its big brother Rallon, the Occam Silver takes advantage of a tapered, 1 1/8-1.5 headtube. A tapered headtube allows for a more robust front triangle, increasing stiffness and riding precision.
Sealed Bearings: The Occam share the same sealed bearings constructive solution with the Rallon. A bike with 4 pivots would have 8 bearings. Ours has 10. Why? The sensitivity offered by this bike is unmatched because typical pivot point bushings or bearings have been replaced by high-quality sealed bearings, including the use of bearings on the shock mount. With this we get an extreme rigidity at pivot points, greater shock sensitivity and the dramatic reduction of stiction.
Direct Post Mount: Why use unnecessary hardware between the frame and rear brake calliper when the brake can be mounted directly? We have eliminated two bolts and an adapter creating a cleaner, lighter and stiffer attachment, minimizing braking noise and flex.
