_MRP2846Last year at a press event, I spied a Rocky Mountain employee riding a prototype 27+ FS bike based on a converted Rocky Mountain model.  I was sworn to take no pics, etc, but it was most likely what led to this…the Pipeline.

The Plus bike freight train rolls on.

The video is pretty hilarious and it echoes and parodies some of what you might be reading or hearing in the innerweb or in bike shops or trailheads…do Plus tires “Dumb down the trails”?

Well, I sure cannot ride like Wade and never will, and I do not have that kind of riding terrain around here, but it resounds within me as well…27+ is not even hitting its stride yet and I cannot imagine it not revolutionizing how we look at trailbikes in the future.

The Pipeline certainly slots into the more aggressive end of things, but there is also the Scott Genius LT Plus, the Ibis Mojo 3, and the Specialized FSR 6 Fattie to choose from.  There will be more.  It will be interesting to see what Trek does here as well as Cannondale, when they jump into Plus.  ‘Cause you know they will have to.



Wheel Size: 27.5+

Intended Use: Aggressive Trail

Front Travel: 150mm

Rear Travel: 130mm

The confidence of plus-sized tires in raw, technical terrain is now available in an aggressive trail chassis. The new Pipeline plows through greasy roots and square-edged chunder with authority, while providing near limitless traction on rocky, slippery climbs.

“Early on in testing I realized I could take the ‘stupid lines’ on our local North Shore trails and the big tires would just flow straight through them,” said product manager Ken Perras. “The more technical a line, the more I felt like I was cheating.”

The Pipeline is based on our much-loved Instinct platform. Like the Instinct, the Pipeline is stable and balanced, with a massive range of adjustments available thanks to RIDE-9. A neutral bottom bracket drop and plus-specific fork offset contribute to an intuitive ride feel with excellent steering dynamics.


Riders attacking technical, choppy terrain will immediately feel the benefits of high-volume plus tires. Their large contact patch and lower pressures improve traction, mud shedding, and small-bump compliance for more on-trail confidence.


  • The RIDE-9™ system allows riders to adjust geometry and suspension rates to specific riding styles, terrain, and rider weights. Nine configurations are possible thanks to two interlocking chip inserts that move on two separate axes.


  • Smoothwall™ carbon uses one of the world’s most sophisticated carbon processes to build frames with industry leading stiffness-to-weight, ride quality, and durability. By using rigid internal molds, we are able to perfect the shape of the internal features and eliminate excess materials. We use different types of carbon in specific frame areas to maximize stiffness and impact resistance while minimizing overall weight.
  • FORM™ alloy tubesets are engineered for specific purposes within each frame, ensuring optimized strength, weight, and ride quality. FORM™ tubesets use premium materials to meet our strict requirements.
  • Smoothlink™ suspension stays supple yet supportive through a wider range of gears than conventional single pivot or other four-bar suspension configurations. This patented system reduces both pedal-bob and bottom-outs, while allowing us to fine tune variables like braking and climbing traction across a wide range of intended uses.
  • BC2™ pivots are lighter and stiffer than conventional bearing pivots. Unlike other bushings, our patented system uses a hardened alloy insert that bottoms out to control the contact of the bushing surfaces, reducing the preload that causes stiction and binding. BC2™ Pivots also feature grease ports for effortless maintenance.
