Rocks, roots, and obstacles are there to be enjoyed — Orbea Rallon
This is the Occam’s big brother, and the Rallon takes over in impossibly difficult terrain where the Occam heads for the trailhead. Its 150mm of rear suspension provides another inch of travel to soak up truly rugged trail obstacles with ease. It’s a product of the same Advanced Dynamics technology as the Occam, so bump absorption is only part of its bag of tricks; it pedals as well as it descends, and this is why it’s such a perfect bike for riders who like to earn their descents by riding to the top.
We used Advanced Dynamics to model the suspension function with different riders and terrains, and we were able to optimize the location and length of the suspension pivots and linkages to shape the leverage rate curve to work in harmony with the spring rate curve on the custom-valved Fox RP23 XV air shock. The result is a rear suspension and linkage that we call Lambda Link, in reference to the shape of the graphed leverage rate curve. The leverage ratio change results in a bike that feels like it is coil-sprung without the weight penalty. By saying this, we mean that it responds easily to small bump input, provides a firm mid-stroke for pedaling efficiency and stability in deep berms and through whoops in the trail, and it pushes through the progressive, rampy end-of-stroke spring rate to give you full travel over big hits.
Since we intended the Rallon to be super-capable and to be the bike that you’ll reach for when you expect the unexpected, we created it with our Enduro 3 Geometry. The balance of high-speed stability and steerability for technical terrain was paramount. It’s been optimized for suspension forks between 150 and 160mm of travel. With the shorter fork, the Rallon has a 68° head angle and a 73° seat angle. Choose this configuration if you tend towards riding slower, more technical trails. The longer travel option slackens each angle by a degree, and it slows the steering a bit. This option makes the bike more stable at high speeds and through cobble filled, rutted descents.
Either way you build it, the Rallon is meant for serious abuse. It’s created from our hydroformed, triple butted aluminum tubes. It is TIG welded and heat treated to T6 before we apply the finish. The massive tubes in the front triangle give it outstanding torsional stiffness, and along with the tapered head tube the combination makes for precise steering in even the sketchiest of corners. In keeping with the stiffness of the front end, the rear suspension pivots on sealed cartridge bearings at every point and is anchored by sturdy 28mm bearings on the main pivot. We even support the main shock mount with bearings instead of the usual bushings. This helps to create a suspension that is as active as possible to respond to bumps big and small and one that remains as smooth after a few season of hard riding as it does out of the box.
The Orbea Rallon uses our Downtube Cable Highway routing system to ensure optimum performance and to complement the sleek design of the frame. The underside of the top tube also has threaded inserts to add an optional Highway Cable Kit for a seatpost remote. The Rallon is designed to use either 150mm or 160mm forks, and it is built with an interchangeable dropout system that can accommodate standard quick release or 12x142mm rear hub configurations.
