The RMU NIGHTTRAIN The RMU NIGHTTRAIN is built for riders who want a true freeride/enduro crossover machine capable of handling everything from bike park laps to aggressive backcountry descents. Designed as a long-travel 29er freeride bike, the NIGHTTRAIN combines 170mm of travel with innovative mid-pivot suspension and Dave Weagle’s Orion suspension platform to deliver exceptional traction, control, and support at speed. Its unique dual idler drivetrain and two-chain drivetrain system help reduce pedal feedback while improving suspension performance through rough terrain. Built from durable aluminum, the NIGHTTRAIN stands apart from traditional alloy mountain bikes by blending playful freeride mountain bike characteristics with the efficiency and capability expected from a modern enduro mountain bike. FEATURES Size Specific Geometry and Kinematics: RMU designed the NIGHTTRAIN with size specific geometry and kinematics. This ensures that whether you're on an S1 or S4, that you are getting a bike tailored for you and the way you ride. 170mm of Pure Confidence: With 170mm of travel, the NIGHTTRAIN is built to swallow rock gardens, huck-to-flats, and steep technical chutes while maintaining a supportive mid-stroke for popping off side hits. Precision Geometry: Engineered for high-speed stability without sacrificing the "flickability" RMU is known for. It features a slack head tube angle for the steeps and a steep seat tube angle to keep you centered during grueling transfers. Aluminum Mastery: The frame utilizes 6066-T6 aluminum frame, optimized for a perfect strength-to-weight ratio. DW Dual Idler System: The dual idler system on the RMU Nighttrain 170 achieves universal rear drivetrain compatibility by physically decoupling the crankset from the rear shifting system. ABOUT ORION RMU worked with Dave Weagle to use Orion as a 6 bar flexstay design. This ensures precise suspension tuning and pedaling support. The design is supple on the small bumps, but when you get into berms and want to pop features on the trail, there’s support to work with, and as soon as you get into the bigger square-edged hits, that support gives way to big bump compliance. The harder you push it, the more it rewards you Dave Weagle's Orion Dynamics is the latest in a long line of his industry defining suspension platforms. The Orion design provides an efficient and stable pedaling response on both smooth terrain and in the rough, and without even a hint of pedal feedback. Exceptional mid-travel square-edged bump compliance creates continuous traction in varied terrain so you're always in control. Optimized for single-chainring big range drivetrains, its two short links work in concert to provide controlled lateral stiffness and keep braking forces in check when the trail gets rough. Seated or standing, climbing or cornering, jumping or hammering rock gardens, Orion does it all and does it well.
