The Bombora, a "gravel bike" if there ever has been one. It is essentially a slightly sportier version of the Evasion. The biggest difference between the two is the Bombora has a 68mm bottom bracket shell, so it takes a road crank. It's ditched the Rocker Dropout for a simple 12mm thru axle dropout. It has a slightly lower trail number, but just slightly. It is designed around a 650b/ 27.5" wheel with a 2.3" max tire size. It has lighter tubing than the Evasion for alittle less weight and more speed for when you wanna ride MidSouth. The Bombora is still sporting all of the braze-ons to have some racks, fenders, or whatever you want hanging off of it. A great do-it-all bike from multi-day trips, commuting to and from work, or getting out for a fast rip.
IMPORTANT: The Bombora is NOT a mountain bike. Yes, we know it fits a large tire, but the tube set is light. Think about it as a "plus" size tire gravel bike. We keep the tube set light to keep the ride quality opulent. That means its great for bombing some road/ groads, but its not meant for single track or a big chunky jeep trail full of rocks and huge ruts for you to run into square on. If you do ride it on that kind of stuff and break it, we will not replace it.
Build Notes:
Designed around a 650b/ 27.5" Wheel with a 2.3" max tire size.
If you want to run it 700c, your max clearance will be a 48mm tire.
Takes a ROAD crank. Ideally 1x with a maximum 44 tooth chainring. You can set it up 2x, but it's on you to figure that out.
The Bombora uses Flat Mount Calipers front and rear. If you're struggling to find a brake setup, the Crust Palm Oil Brake Kit will help solve that problem.

Front and rear thru axles are included.
