Sneak Peek: Guerrilla Gravity Megatrail - Made in Colorado 13

We have been eagerly following the progress of Colorado-based Guerrilla Gravity ever since the initial prototypes of the GGDH downhill bike, the young company's first offering. When we went to visit their factory/shop in Denver at the end of 2013, we were intrigued to find an aggressive trail bike in the late stages of development as well.

Today, Guerrilla Gravity are releasing the MEGATRAIL (it sounds better in all caps), a mid-travel trail/enduro/all-mountain/do-it-all bike that looks to follow in the footsteps of its bigger brother, the GGDH. The Megatrail is based around the same concept as the DH bike, putting fun first with a roomy cockpit, low bottom bracket, relatively short chainstays, and a slack head angle.

The frame employs a single-pivot, linkage-driven suspension layout providing 150mm (5.9-inches) of rear wheel travel, which has been developed together with Cane Creek for the DBair CS and optimized for air shocks in general. The design goal was to create the perfect mix of small bump compliance, big hit absorption, and pedal efficiency, something Guerrilla Gravity feel they have been able to achieve. High quality Enduro Maxx bearings are used at all pivot locations.

Diving deeper into the details, we find a 142/12mm Syntace axle in the rear, a straight 1.5-inch head tube (giving riders the option to run a Cane Creek Angleset if they want a slacker front end), internal cable routing for stealth-style dropper posts, and a threaded 73mm bottom bracket. There is an E2 front derailleur mount, as well as an optional ISCG5 mount if you want to run a frame mounted chainguide/bashguard. Guerrilla Gravity is also offering a 42-tooth cassette add-on dubbed the "BFC" for those wanting more range out of their 1X drivetrains.

The Megatrail is available with both 26 and 27.5-inch wheels (a 27.5/26 front/rear combo is also possible), where both the front and rear triangles are specific to each wheel size in order to keep the bottom bracket and headtube heights constant. Frames start at $1,925 (without shock), while four complete build kits are available from $3,495 with some customization options.

We'll be throwing a leg over the Megatrail shortly, and we'll be bringing you our detailed ride impressions and additional specs when we do. The bike still has a few secrets to reveal...

To all the size skeptics I say ride the bike. I originally thought the same thing that everyone is commenting about but after riding the bike. I'm 5'10" and will be buying a medium.

MegaTrail eTT on the size small is about the same as a Specialized stumpy large. Huge wheel base too. Whats the cornering like?

Hey Mike,

A lot of back-and-forth went into the sizing after initial skeptics were concerned it would be too long. But once you take the average length stem spec'ed on bikes (60-70 mm) and combine it with the average seatpost offset a lot of folks run (15-25 mm), the number you come up with is not much different for given rider height recommendations. And the small bit of extra room in the cockpit you are left with is good for getting rid of that cramped cockpit feel that a lot of trail bikes have and is what you want if you're trying to rad on the trail (note lengthening downhill bike cockpits)... The bike corners f*ing awesome. The BB is lower than both the Stumpy and the Enduro, both of which have a tall, on-top-of-the-bike feel to them when I tested them getting data together for the MT. Standover is also improved over these bikes because of that, which also increases the "nimbleness" in the corners. And standover on the small frame is even better, bc we were forced to get rid of the bottle cage in the front triangle. We haven't had the chance to test that yet, as that bike was built yesterday, but it looks like it's going to be super playful. Finally, the chainstays are short, which give you a little more snap in the rear.

Feel free to come up to the shop to check 'em out yourself!

Cheers,

Will

Cool I would love to throw a leg over one and check it out. I haven't been down to your shop yet. When I get a min I will stop by!

Size Large Stumpjumper: 24.5" ETT, plus what appears to be about 1.5" of offset at the seatpost and what appears to be a 70mm stem. Adding those extra lengths makes for a butt-handlebar length that's about 2" longer than the Small Megatrail.

I love the looooong sizing of this thing. Like the "*measured with 1/4-inch seatpost offset" makes any real difference lol.

It can make a difference, which is why we mention it. For example, one skeptical rider was questioning the length, as the frame itself was longer than his current rig. Then, after realizing he was running over an inch of offset at the seat post plus 20mm longer stem length, he agreed the MT package made more sense.

5'9" is the borderline between Small and Medium, and also recommended for the size Small.

The Megatrail is designed for short stems, and those numbers include 1/4" of offset at the seat post. Riders that have ridden the MT have agreed with the sizing so far, including people that were initially skeptical of it being too long. Measure the actual butt to handlebar length you're running now, and compare it running 1/4" offset and a 35mm or 50mm long stem on the MT. Most people are surprised that the MT numbers suddenly make sense then.
Or, if you're near Denver, come on down and try one out. We also have more travelling planned for this year for demo rides, so keep an eye out for those.
