Jack Kane Battle Axe SL

Battle Axe SL Carbon Frame

Not everyone craves a pure-race machine because it can be too taxing on one’s body, so we designed our Battle Axe SL. We never want to sacrifice your ride quality, so our goal was to maintain responsiveness, lightness, durability, yet find the right balance between stiffness and compliance. We designed around you — every tube serves a purpose.

The Battle Axe SL is the curviest frame we offer, but the curves are not for simply looking good. 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 aero wheel well “axe” is pronounced for those desiring to reduce air flow and shield their wheel from the wind. The unified chain stays help minimize flex while sprinting/pedaling to maintain torsional stiffness, which leads to efficient pedaling and preventing fatigue. All of these traits combined create one exceptionally smooth machine.

Our philosophy on our tapered headtube: We want to maximize stiffness in the front by trying to evenly distribute 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.

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