The Rocky Mountain Underground (RMU) Nighttrain is an intriguing addition to the world of mountain bikes, offering a unique blend of innovation and tradition. This enduro bike is a testament to the brand's ability to push boundaries while staying true to its mountain-focused roots. With a focus on dual-sport capabilities and a suspension system that's both advanced and familiar, the Nighttrain is a bike that demands attention and warrants a closer look.
One of the most striking features of the Nighttrain is its dual-idler drivetrain. This design, which uses two chains to overcome the friction of a conventional single idler layout, is a bold move that sets the bike apart from its competitors. The use of two chains is not just a novelty; it's a practical solution to a common problem in mountain biking. By reducing friction, RMU has created a bike that is more efficient and responsive, making it an ideal choice for riders who want to tackle a variety of terrain.
The suspension system, dubbed Orion, is another standout feature. Designed by Dave Weagle, who is known for his innovative suspension systems, the Orion suspension is a 6-bar flex stay design that offers a unique blend of suppleness and support. This system is a testament to Weagle's expertise and is a welcome addition to the world of mountain biking. The fact that the Nighttrain uses a 230x65mm Metric shock, instead of a trunnion-style shock, is a detail that many consumers will appreciate, as it can lead to more efficient pedaling and a smoother ride.
The Nighttrain's geometry is also worth noting. With a long and slack front end and a short rear half, the bike offers a unique balance of stability and agility. The use of a 29" wheel in the rear is particularly interesting, as it allows for better maneuverability around tight corners and obstacles. The bike's overall design is a testament to RMU's commitment to creating a bike that is both capable and versatile.
In terms of pricing, the Nighttrain offers a range of options to suit different budgets and needs. The entry-level complete bike starts at $4,999 USD with Shimano Deore components, while the more expensive XT build kit with electronic shifting and Fox Factory air suspension is priced at $6,999 USD. A pure gravity-oriented option, featuring a 190mm-travel Fox 40, is also available for $6,499 USD. These prices are competitive, especially considering the bike's advanced features and innovative design.
Overall, the RMU Nighttrain is a bike that is sure to turn heads and spark conversations. With its dual-idler drivetrain, advanced suspension system, and unique geometry, it offers a fresh take on the enduro bike category. Whether you're a seasoned mountain biker or a newcomer to the sport, the Nighttrain is a bike that is worth considering. So, if you're in the market for a new enduro bike, be sure to keep the RMU Nighttrain in mind. It just might be the perfect addition to your riding arsenal.
