There’s a decent chance that you haven’t heard of Guerrilla Gravity. They have no worldwide dealer network, they don’t sponsor high-profile UCI teams, and they don’t employ a well-known former frame-builder from the 90’s trying to remain relevant who’s claim to fame is a weird shaped gusset or some such thing that people used to think was important.
What they do put out there is two pretty conscientiously thought-out, hand built aluminum frames fabricated in Denver, CO. A trail bike and a DH bike comprise their line up, and they’re made in America, when very little else on a bike is these days.
I got to test out the Megatrail, as described here:
Full geometry charts are listed in metric and ‘murkin units on the site, and there is also an Owner’s Manual.
Something that stands out here is the seat tube angle. It’s 74 degrees, which for a bike this slack, really keeps it in the game when things get steep on climbs. It also won’t put the seat behind the wheel for the long-legged crowd when they need 8 feet of seatpost to reach their butts. The Megatrail is certainly among the breed of newer longer trail bikes that from the outset are intended to be ridden with short stems, like 50mm or less.
Guerrilla Gravity is kind of unique in what they sell. You can literally build up your own bike, component by component on their website.
Brakes, drivetrain, cockpit bits, wheels and suspension are all represented by the major players, (Sram and Shimano for drivetrain and brakes, Fox, Cane Creek, and Rockshox for suspension) as well as an MRP or Suntour fork if you so desire. It’s not a free for all—you won’t find Marzocchi or DVO in there—but considering how much say you normally get in a prepackaged complete bike sale, it can be pretty damn personalized.
You can also of course, just buy the frame, as in literally the frame with no shock. I imagine they’d probably do any range of build in between those two extremes as well if you don’t like your choices on a particular component.
They also offer the frames in my favorite, 26” wheels. If you go that route, you get half an inch off the chainstay (17.3” for the 650b vs. 16.8” for 26” wheels) and therefore half an inch off the wheelbase of their published geometry numbers, which are for the 650b frames.
I’m 5’8”, which puts me at the upper end of what Guerrilla Gravity recommends for a small. They had a medium 650b demo frame available, so that’s what I tested. The bike showed up in this configuration:
After weighing the demo bike (with pedals), that estimate is pretty damn close. I got 29.8lbs with some no frills Deity flat pedals and WTB Frequency i23 rims, which aren’t listed in their build options.
$5,530 isn’t cheap, but it’s also not out of line with other aluminum completes from most other manufacturers with this caliber of build. In fact there really aren’t that many out there with those parts. I know you’re thinking about that fork, but a solo air RS Pike is the same price, and a Fox 36 Float adds only $235 to the total. They’re competitive at least.
