Ever notice how tired you can be after riding on rough roads? It’s because our bodies have to absorb the never ending vibrations our bikes ride over — taxing us both physically and mentally. So, how could we reduce the amount of road chatter your body takes in? We designed our Battle Axe SL.

The Battle Axe SL is the curviest frame we offer, but the curves are not simply for appeal. They serve a purpose. The dual seat stays are bowed to minimize high frequency road vibrations all the way up to the seat tube. Why should you care? It means a smoother ride for you. If your local rough roads are wearing you down, this frame will help alleviate that nuisance. The winged seat tube “axe” is pronounced for those desiring to reduce air flow turbulence to the rear wheel. The unified chain stays help minimize flex while sprinting/pedaling to maintain torsional stiffness, which leads to efficient pedaling and minimal power loss. All of these traits combine to create one exceptionally smooth machine. We never sacrifice your ride quality, so our goal is to maintain the big three — responsiveness, lightness, and durability. We have found the right balance between stiffness and compliance. We designed around you — every tube serves a purpose.

Our philosophy on our tapered head tube: We maximize stiffness in the front by evenly distributing stresses and loads the bike faces during rides/races. As a result, the ride feels more reliable and assured. We achieved this with the beefier 1-1/2″ bottom.

Female riders have the option of having the frame model be “K Pro Carbon” instead of Battle Axe.

At no point did I feel like the bike was wasting any of my energy. Descending is confidence inspiring on this bike. The first real descent I rode was about 3 miles long with the last 1/3 of a mile between 15-18% with tight twisting turns and it felt like I was on rails. I felt like I looked like a moto GP racer navigating a chicane. I was able to move the bike under me effortlessly and lay it from side to side quickly and with kind of poise that can get you in trouble! ~BikeRumor
