2017 Guerrilla Gravity The Smash Ride 1

(discontinued)

What began as a friendship within Colorado's once thriving downhill racing scene has since turned into a full-time bike building endeavor, and the partners heading up the Denver-based Guerrilla Gravity bike brand continue to push ahead with interesting new designs. Month after month they keep exceeding projections, and we're certain a good portion of their continued organic growth is a result of listening to the people.

Their latest creation, The Smash, is about as true to their roots as a trail bike can be. "Guerrilla" is a community driven effort to spark change, and "Gravity" is the funnest part of mountain biking. This 140mm travel 29er came about by taking feedback from existing Guerrilla Gravity riders who wanted more compliance and more travel than the 29-inch Trail Pistol mixed with the DNA of the ultra-capable 27.5 Megatrail. With a goal of making a ride anything type of bike with a balanced overall feel, this rig is meant to be equally at home crushing big backcountry descents and ripping bike park laps. The best part? It's like two bikes in one thanks to a clever suspension feature.

During the five years Guerrilla Gravity has been in business, clawing away at making a name for themselves and a dent in the bike industry, it almost goes without saying that they've learned a lot. From how to make their business more efficient to how to narrow in on increasingly tight tolerances, in many ways their latest crop of bikes are the company's next generation of designs. Not only have they improved various usability aspects, but their new designs are also more modular and easier to manufacture. Like many larger brands they are able to carry consistent features (and sometimes tubing, etc) from bike to bike, creating a more cohesive package.

The Smash has been in the idea bin for around two years, and four months ago they decided to pull the trigger and make it happen. With frames available starting this month, the short timetable is a testament to how quickly the small brand can move. The bikes are designed and manufactured in-house, and their "holistic structure allows them to maintain tight quality controls, have a short and efficient supply chain, and offer riders extensive customization options."

Their no-nonsense approach is evident when looking at the finer details. Things like external cable routing, a threaded bottom bracket, large diameter headtube, easily accessible frame hardware, a bottle mount, and the clever spare tube/tool NUTS bracket will make it appeal to many. Opt for the raw color and you can simply whip out a Scotch Brite pad the next time you lay it over to restore the finish.

Compared to the Trail Pistol, which we previously noted had a slightly flexy rear end, this new ride features a significantly beefier and stiffer back half thanks to the use of the same seatstay tubing as the burlier Megatrail.

You'll also find ample tire clearance, even when sporting some proper 29x2.5-inch tires, but unlike the Trail Pistol this one isn't a plus-size tire compatible ride. Why? Simply because it's a more aggressive bike and Guerrilla Gravity didn't feel it made sense.

Crush & Plush Suspension Modes

One bike, multiple personalities? That's definitely the case this time around depending on the shock choice and suspension configuration. The Smash has both "Crush" and "Plush" suspension modes that you can select by flipping a chip in the rear shock mount. As with all Guerrilla Gravity bikes, The Smash was designed with versatility in mind. Changing modes impacts the suspension leverage curve and how the bike rides, but has no impact on the available travel.

Riders can choose between Crush Mode and Plush Mode to dial in the suspension platform that’s ideal for their local terrain. Crush mode has a more supportive mid-stroke for flow trails and all day trail rides, while Plush mode is softest off the top, making it the go-to for plowing into rocks at mach-chicken.

For those that have yet to taste mach-chicken, it's damn good, especially with some Guerrilla Gravity seasoning. Plush mode's added compliance allows the rear wheel to get up and out of the way in a hurry to prevent you from getting jarred to bits. Those searching for an efficient, supportive, poppy ride that you have to push harder into to get to bottom may find Crush mode to be preferable on big rides, fast and smooth singletrack, or flow trails.

"Compared to our other models, The Smash’s leverage curve is tuned to be softer off the top, where most of 'the smashing' occurs, and then have more ramp up for hard hits."

Switching from Crush to Plush is a one minute job that can be executed on the side of the trail when conditions call for it. An o-ring around the flip chip ensures they don't go flying when you push them out of the frame and keeps everything secure.

The dual mode feature stems from Guerrilla Gravity engineer Matt Giaraffa's time in the car racing world. Similar to how you can swap dampers or any number of settings in a race vehicle to suit course conditions better, they wanted to work something similar into this (and every Guerrilla Gravity) bike.

"We all want our bikes to be dialed in exactly for what we're doing. Your preferences are going to be different than mine and mine from yours, so we always try to incorporate that into our bikes. That, plus bikes are expensive. We're not trying to get someone to buy a whole new bike because they want it to ride slightly different, so it makes the ownership more valuable if the bike can be adjusted to different preferences. Creating versatile bikes is important to us."

Air & Coil Shock Options

From the get-go The Smash was designed to work with both air and coil shocks, though all but one Guerrilla Gravity employee runs the coil.

Riders can also choose between an air shock and coil shock. Designing a platform that works well with a coil shock was a priority given the bike’s intended use: smashing whatever is in front of you.

"As a general guideline, we recommend running an air shock for a lighter weight trail setup and for those that don’t have exceptionally rocky or loose terrain, while a coil shock is ideal for those that prioritize small bump compliance and traction over weight."

By carefully considering the suspension kinematics, all shocks were able to be tuned to the middle of the adjustment range to allow the bike to work for a wide range of riders. The RockShox Super Deluxe air shock comes with one volume spacer installed which allows room for more or less ramp on a rider-by-rider basis.

Also interesting is the use of a relatively long 57.5mm shock stroke for the bike's 140mm of travel. This is neat because the low leverage ratio results in a 180-pound rider needing a 350 pound-per-inch coil spring rate, which has a lower weight penalty than the beefier springs required for many bikes when swapping from air to coil.

Geometry

*The Smash accepts forks between 140 and 160mm of travel. Changing the travel +/- 10mm creates a head angle (HA) change of +/- .4º and bottom bracket height change of 3mm (0.1-inch).

Looking the numbers over you're bound to see a few things jump out at you, including the longer than normal reach values, sizable wheelbases, and steep actual seat tube angle. That steep seat angle is key to their creation, allowing you to ride a longer and more stable bike that doesn't feel cumbersome when seated.

"The Smash utilizes the same steep actual seat tube angle geometry found on Guerrilla Gravity’s other models. It’s important to note that it's the actual seat tube angle, as effective seat tube angles can be misleading. A steep actual seat tube angle allows for an upright, efficient climbing position at any saddle height."

Compared to a bike with a "bent nail shape" seat tube, Guerrilla Gravity's take maintains more consistent geometry as the saddle is raised and lowered. This improves climbing efficiency for all riders, especially the long-legged ones among us.

On The Trail

Not long ago we tested the shorter-travel Trail Pistol during Vital's 2017 Test Sessions. While awesome in its own right, the bike required us to pretty much pin it non-stop to really make the suspension work for us. That's fine when you've got the energy to keep up the pace, but as you tire it can become more difficult to hang onto. Knowing that The Smash was designed to be a bit more supple but with added bottom-out support, we were eager to see how it'd translate to the trail. Combined with Guerrilla Gravity's lengthy chassis and a name like "The Smash" we hoped for good things as we set off on two days of testing on four very different types of trail areas in Durango, Colorado.

Setting our size medium test bike to 30% sag while seated, the bike provided a similar amount of rear wheel sag as the Megatrail to help with that off the top feel. We had the opportunity to ride in both suspension modes using both an air and coil shock for a total of four combinations:

Crush Mode / Air Shock

We kicked things off with a warm up in the high country with a lap on Engineer Mountain Trail, which features big views, a relentless climb to the top, and a ripping high-speed descent at a moderate grade. The bike was sporting a 140mm RockShox Pike fork and Super Deluxe RCT air shock.

Its length makes it quite hard to turn around tight corners. While this is an area where many bikes struggle, it was readily evident that this was a big shortcoming. Riders with trails covered in switchbacks will want to look elsewhere.

It was on this trail that we also experienced the only major downside to The Smash – its length makes it quite hard to turn around tight corners. While this is an area where many bikes struggle, it was readily evident that this was a big shortcoming. Riders with trails covered in switchbacks will want to look elsewhere. Never in the last several years have we had to adopt such an odd technique to get a bike to come around a turn. Provided you have wide sweeping corners, bermed or otherwise, it works well however.

What's The Bottom Line?

Part monster truck, part bicycle, The Smash delivers a highly tunable ride to suit a variety of trail types thanks to two suspension modes and customizable build options. As the name suggests, it'll shine brightest for the person who loves going all out in ugly, rough, and rocky terrain with an excellent ability to carry speed through the chunky bits. Our suggestion? Embrace the true nature of The Smash. Opt for a longer travel fork, wider front tire, and coil shock, then drop it in Plush mode and let the real fun commence.
