After a lot of rumors about prototypes and almost 4 years of development, Rocky Mountain’s new DH bike is finally here. While the prototypes seen were mostly made of aluminum, the new Maiden is a stunning carbon work.
Not satisfied with abandoning 26 “wheels, Maiden accepts both small and medium rims without sacrificing geometry. Additional adjustments in angle of attack and new suspension design form a long-course bike, perfect for racing, days in the park, or for simply plunging downhill.
Using a frame for two wheel sizes, the Carbon Smoothwall construction is used for all frame, links, chain stay and seat stay. Pivot axes with Pipelock tongs generate wide pivots that allow lightweight components. All pivots use Enduro Max cartridge type bearings.
The details of the frame include PressFit 107 central movement, 157mm spacing rear axle and ISCG 05 chain guide holder. The steering lower spacer is removable, and together with a secondary position for the rear axle allows the use of both sizes. Wheel system called the Equalized Wheel Concept. The position of both wheel sizes maintains the central movement and the angle of the fork in the same position. In addition, the Ride-4 suspension system allows 1/4 ° changes in angle of attack without changing suspension settings.
The internal routing of cables is future-proof, compatible with Di2 electronic gearbox and with internal support and very discrete for battery. Finally, integrated protection was included in the frame to protect the carbon, with a shell molded just above the central movement, at the bottom of the pipe, suspension protected by the lower pipe and chain stay protector.
On the suspension side, the Maiden was built using a specific damping curve designed to capture the best attributes of the 4-bar suspensions. In order to provide a pedal with an emphasis on cushioning small bumps, while still providing sufficient support in the mid-stroke and also in sag, the Maiden uses a 40 degree angle on the upper tube of the rear triangle, which remains low at the beginning Of flexion and high at the end, allowing the use of lighter springs. Using a nearly constant rate of increase, the system design is user friendly with suspensions and allows for more effective adjustments.
The pedaling efficiency announced is 140% with wheels 27.5 and 100% with 26. The increase of the chainstay has been limited to improve the sensitivity to small impacts. To improve the performance of the suspension during braking, the Rocky’s Autonomous Bracking design utilizes a virtual swingarm concept. The virtual axle starts behind the bike and extends backwards as the suspension squeezes, ending in front of the bike. The idea is to avoid stiffening of the suspension during braking, which causes the traction to break.
Working together with BOS nad suspensions, Rocky chose the company for its bumper, effective adjustments and build quality. BOS suspensions are found on all Maiden, both front and rear with 200mm stroke, except for the Park version, which uses X-Fusion suspension.
Available in four different models, all running at 27.5, the top of the Unlimited line comes out. The Maiden World Cup is an incredible bike, followed by Pro and Park. The frames will be available with BOS Stoy RaRe rear suspension. Bikes and frames will be available at the end of October around the world. Stay tuned to Rocky’s website for more specs.
