"The Nighttrain is a brand new long-travel enduro bike from RMU. It features the latest iteration of Dave Weagle's Orion suspension design in a 6-bar flexstay layout with a mid-pivot location and dual-idler, dual-chain drivetrain setup. That unique suspension platform controls the 170mm of rear wheel travel on the 6066-T6 aluminum frame. That's meant to be paired with a 170mm fork, though RMU is also offering a "DH" build with a 190mm fork. The Nighttrain rolls on 29″ wheels front and rear."
"The Nighttrain has 12 x 157mm Superboost rear axle spacing, which was apparently needed with the suspension design and the dual-idler, dual-chain setup. It has 136mm Boost crankset spacing and uses a 73mm BSA threaded bottom bracket. The frame features internal routing for the shifter cable and housing, while the rear brake line is routed externally for simplicity and ease of maintenance."

RMU has launched its first mountain bike, the Nighttrain, a long-travel enduro platform built for fast, aggressive riding. The bike uses a 6066-T6 aluminum frame with Dave Weagle’s Orion suspension in a 6-bar flexstay layout with a mid-pivot and dual-idler, dual-chain drivetrain. Rear wheel travel is 170mm, paired with a 170mm fork in the standard setup or a 190mm fork in a “DH” build. The bike runs 29-inch wheels front and rear and uses a 157mm Superboost rear axle spacing, 136mm Boost crank spacing, and a 73mm BSA threaded bottom bracket. Internal routing is used for the shifter cable and housing, while the rear brake line is routed externally for easier maintenance.
