Rocky Mountain Underground (RMU), traditionally renowned for its high-performance skis, is venturing into the mountain biking arena with the introduction of the Nighttrain, a 170mm-travel enduro bike. This ambitious project is the result of a collaboration with esteemed suspension designer Dave Weagle, best known for his dw-link suspension systems.
Innovative Suspension Design
The Nighttrain features a mid-pivot, six-bar suspension layout, a design Weagle describes as a “new generation Orion suspension layout.” This configuration aims to deliver exceptional performance for aggressive riding styles. Complementing this is a dual-idler, dual-chain drivetrain, engineered to achieve an elevated chainline—a crucial aspect for high-pivot suspension designs. Weagle notes that this setup is the most efficient method to attain the desired chainline elevation. (pinkbike.com)

It boasts internal routing for the shifter cable and external routing for the rear brake line, maintaining a clean and efficient design.
