Guerrilla Gravity Announces Two New Megatrail Models

"As a highly refined and extremely versatile trail bike, the Megatrail is built for everything from conquering high-alpine adventures to shredding bike park laps, or just slaying your after-work rides. And when it’s time to turn the Rad up to 11, Gravity Mode™ provides a 30-second, one-bolt geometry toggle that transforms the bike into a downhill dominator--it's like having two bikes!

The Megatrail's design achieves best-in-class pedaling, next-level cornering, and downhill authority. The leverage curve works well with both air and coil shocks, providing support while pedaling, small bump sensitivity, and progression for hard bottom-out resistance regardless of shock choice. Extremely well-tuned anti-squat characteristics and mid-stroke support create a very efficient pedalling platform.

We used our background in racecar engineering to create the Freedom Linkage, a versatile platform that allows you to dial in your ride characteristics based on local terrain and rider preferences via shock tunes; the base tune is designed with advanced riders in mind.

Frame Features

• Trail Mode and Gravity Mode™
  • Trail Mode: 150 mm travel, 13.4" BB, 66.2º HA
  • Gravity Mode™: 165 mm travel, 13" BB, 65.5º HA
• Freedom Linkage using proprietary Horst Link implementation
• Steeper seat tube angle maintains consistent geo as the saddle is raised and lowered, improves climbing efficiency
• NUTS (Necessities Under the Saddle) Bracket keeps your flat changing essentials easily accessible (and lightens your load)
• Bottle mount in front triangle
• Premium Enduro Maxx cartridge bearings last longer (they have more balls)
• 6.6 lbs. (2,993g) frame with hardware (size Medium, no shock)

It also utilizes our approach to design that focuses on a high level of refinement to eliminate unnecessary complication. This creates a platform that's made for goin' fast, yet is easy to maintain and built to last. Plus, it's built right here in our shop. Those are pure American welds (f* yeah!)!"

Frame Fittings

• 30.9mm seatpost (34.9mm clamp)
• 49mm headtube, fits tapered steerer tubes
• ISCG05 chainguide mount
• 230x65 mm shock
• Threaded 73 mm BB spacing (no creaky press fit BB here!)
• 55mm chainline
• 12x148 rear axle, offset 3mm to the driveside for optimal chainline and clearance
• Universal Syntace rear axle and derailleur hanger
• ISO brake caliper mount
• Max fork travel: 180 mm
• Max tire size: 27.5x2.6

The Megatrail SS

"Turning your local trail into your very own slopestyle track, the SS lets you pump, jump, and weave through the woods. With an exceptionally lively platform, this is the bike for those that value playfulness more than smashing the super-gnar. Plus, with Gravity Mode™ available, you still have the downhill chops when going gets rough...er.

The shorter travel Megatrail sibling has 135 and 145 mm travel in Trail Mode and Gravity Mode™, respectively. It uses the same platform at the "full-strength" Megatrail, so you have the same frame stiffness and ride qualities, but with a "fun size" suspension package that allows you to run up to 27.5x2.8 Plus tires.

* The Megatrail accepts forks between 150-180 mm of travel. Changing the travel +/- 10 mm creates a head angle (HA) change of +/- .4º and BB height change of .1" (3 mm).

** Please note that with a steeper seat tube angle reach numbers may seem longer compared to the "average" reach numbers of other bikes. For further sizing advice, please email us.
