The Guerrilla Gravity Megatrail has a split personality, enabled by one of the more noticeable geo flip chips we’ve ridden. The largely perceivable differences in ride characteristics make the Megatrail a solid climber and a capable descender. Each time we flipped the chip, we had to double-check that we were on the same bike. It really was that noticeable. We also appreciated just how easy it was to change the chip, which meant we found ourselves actually using the adjustment more than many other bikes we’ve tested. To be clear, the Guerrilla Gravity Megatrail climbs does not like a 20-pound XC rig, but it does hide it’s downhill preference pretty damn well.
On our home trails the bike was undoubtedly overkill, but thanks to the 150mm trail mode, the Guerrilla Gravity Megatrail was still lively and light-footed. Scooting up hills with little to no pedal bob during seated fire roads, the bike surprised us thanks to the supportive shock and climb-friendly kinematics. Out of the saddle efforts on technical trails saw a bit more bob, but nothing out of the ordinary for a bike of this genre. Even on gentle flowing trails, testers still enjoyed the bike. It’s snappy cornering in both geo settings let the bike tackle much mellower trails than it was intended for, but that didn’t mean we forgot to let the bike loose like it was intended to be.
To get a better sense of the bike’s capabilities, we brought it up to Mammoth Bike Park for a full beat down. On jump trails, the bike was an absolute blast. Stable at speed, the Guerrilla Gravity Megatrail welcomes long airtime with open arms and slays berms with the best of them. Landing to flat is encouraged and corner slashing is all but mandatory aboard this rig. Even on the biggest hits of the mountain, the Megatrail was more fun in the air than the dual crown DH bikes we brought along on the trip. In its slackened Gravity mode, the bike rides like a nimble and lightweight DH rig without the sluggish front end. We do have one regret that became apparent when we took the Megatrail into the big boy tech lines.
When discussing the build with Guerrilla Gravity, we opted to go for the cost-effective suspension spec, selecting a Rock Shox Super Deluxe RCT shock and a Rock Shox Lyric RC fork. Though the duo is a solid performer for the price (and we’re big fans of value) we struggled with the lack of adjustability in the rear shock over the high speed, chunky rock gardens in the bike park. When riding full-gas, race pace through repeated large hits, the rear end left us feeling like we were clinging to a bucking bronco. Despite tinkering with any and every adjustment that could be made, the shock just simply didn’t offer the damping tunability that an experienced rider would need to fully let the bike do its job. We couldn’t help but wonder what a monster the bike could have been if spec’d with the Push ElevenSix shock. If you’re an aggressive, expert-level rider that’s planning on riding this bike like a full-blown DH rig, we’d recommend ponying up for the high-end coil shock. For anyone else, the Super Deluxe RCT or even the midline coil Super Deluxe are plenty capable and will get you over 90% of terrain without a hiccup.
Though the bike is in a slightly shorter travel bracket, we couldn’t help but draw comparisons to the Pivot Firebird. Both are gravity-influenced senders, yet the Guerrilla Gravity Megatrail does a markedly better job of balancing that ‘send it’ attitude with daily driver manners. Most of us aren’t doing bike park lines and dropping DH trails every day, so it’s important that a bike in this category can be well rounded and versatile. Thanks to the adjustable geo on the Guerrilla Gravity Megatrail, it excels as a do it all bike for the aggressive rider that still needs to climb to keep up with that one annoying friend wearing lycra.
