Guerilla Gravity Megatrail

Guerilla Gravity Megatrail

I hadn’t even heard of this company 3 months ago but at the suggestion of a couple people who responded to my “What bikes should I ride at Outerbike?” post on mtbr, then reading a long thread about it and checking out their web page I knew I had to ride it. I love small companies started by bikers who are also engineers and are passionate about both. And it’s designed and manufactured all right in their shop in Denver. The Guerilla Gravity guys didn’t have a booth at Outerbike but they agreed to meet me in the late afternoon to show the Megatrail. We met up at Amasa and did the Hymasa to Ahab loop.

The Megatrail is a linkage actuated single pivot bike with adjustable geometry via a two position shock bolt that goes from Trail mode which has 66.5 degree head angle to Gravity mode which drops the bb, lengthens the WB slightly and slackens the HA to 65.5 degrees. The frame looks and feels stiff and burly. I was expecting a heavy bike on par with my 34 lb Knolly Chilcotin but it felt a couple pounds lighter than that when picking it up and felt a couple pounds lighter than that when climbing up the trail. With the bike in Trail mode and the CCDB Air Climb switch on this thing felt quite spritely and responsive going up. It was easy to lift the front end across cracks and gaps and up onto ledges and the rear end followed without squatting or kicking. In my mind the Megatrail is definfitely a bigger bike, more on par with the Nomad, SB6c, Giant Reign, Spartan, etc. but certainly climbs with the these light, mini-link, carbon wunderbikes as well. Despite being a bit heavier than the lightest of these, it didn’t feel heavy or sluggish at all while climbing especially with the CS switched on.

But what the MT lives for is rugged, highspeed, baller descents. When you switch into the Gravity Mode it’s like pulling a mini DH bike out of your pocket. Matt from GG called it the Beast Mode. It becomes lower and slacker and even more stable. It is also very stiff and structurally sound and there was no hint of flex. This particular bike had spent the summer at Keystone Bike Park as a demo and it still felt tight and quiet (except for a creaky Headset that needed a rebuild). Gravity mode was a nice improvement when descending but I wouldn’t say it was night and day. However it started getting dark on us and we weren’t really able to fully unleash the Beast and let it run. Matt was really wanting me to see this dual personality and wanted me to bag my second day of bike demos and go do the Whole Enchilada with them the next day. This bike was so fun I almost agreed to do it. Magically though, when in the trail mode it feels very efficient while climbing and competes very well with bikes like the Nomad and SB6 in this aspect as well.

I liked the bike a lot and the size medium Matt put me on fit great even with a short stem and wide bars. This bike comes in both 26″ and 27.5″ flavors. Matt had both frames there and I got to ride them both. Honestly, the 26″ version climbed very well as I said, but the 27.5″ climbed even a bit better and maintained speed through choppy and more shallow descents slightly better. Overall though, I liked the 26″ version better. It was more compact feeling and maneuverable, accelerated quicker, and felt more BMX tossable. Just a really fun bike. It was also set up a little more to my liking with and MRP Stage fork that was very good. It was at least as good as the Fox 36 and better than the Pikes I had ridden earlier in the day. Whereas the Suntour Auron on the 27.5″ version was not quite as stiff laterally or as plush in its travel. The 27.5 was sporting the DB Inline which worked really well but I thought the DB Air on the 26er was just a bit better. The 26er also had a more agreeable bar/stem relationship for me. Changing these things would probably sway me back to the 27.5″ but I was surprised how much I liked the 26er.

To summarize, the Megatrail does compete with the latest greatest carbon AM/Enduro bikes but you have to be willing to flip on the CS and change out a shock bolt to really extend its range. If you dig small homegrown, made in the USA companies, and want something that’s not like all the other bikes on the trail, the Megatrail may be for you.

I give the Megatrail a grade of A+


MRP Stage fork. I liked it a lot. Wide bars, short stem also like a lot.

Long front center felt good and handled really well. No allowance for front derailleur. Man up.

Matt wheelying away the golden hour. This is the only picture I took of the 27.5″ version. The front and rear triangles are both designed and built specific to the 27.5″ Megatrail.

    • Thanks for the correction. I must’ve misunderstood or misheard what Matt said about that. I’ll edit the text to reflect that.

  2. I rode Will’s Mega Trail at MBO August 2015. Equipped with the Push Elevensix shock. The only climbing was on a short fire road but it offered a firm climbing platform. Going downhill the back tire was glued to the ground. Going over small bumps that normally led to little jumps led to manuals! Very fast and stable descender. A very fun bike to ride.

    • Thanks for the update. I thought the MT stuck to the ground impressively well with the DB Air. The Push ElevenSix must be another level.

  3. Nice review. I’ve owned a MT for about 6 months and just switched from MRP/CCDB to DVO Diamond/Jade coil. Wow! I love the plush of the Diamond’s first few inches of travel mixed with the more progressive remaining travel. That mated to a well designed coil opened even another dimension to this rig. I tested many sexy carbon bikes before riding this and the MT beats them all. The adjustability is a beautiful thing. I go to sleep at night thinking about my next ride. Just rips!!

    • are you still recalling liking the Jade Coil on there? Ive got the same setup as you (MRP Stage and CCDB CS) and found a good used jade coil. Still climb ok with the jade?
