El Martillo CX

"The Hammer "

Steeped in tradition from years of building classic mountain bikes, our El Martillo CX frame has become a classic in its own right. Our aggressive race proven geometry, coupled with our legendary manufacturing skills and Pro-Tour proven smooth welds yields a light yet stable, off-road worthy cross frame that is every bit a work of art as it is a racing thoroughbred.

With sloping top tube, mud clearing chainstay yoke and wishbone seat stays, traditional STI cable routing, Ventana proprietary drawn, butted and ovalized tubing, and US cross racing inspired geometry, El Martillo CX will have you grinning from ear-to-ear and will leave all others drooling in your wake. And with our optional sliding dropouts, El Martillo CX is a road worthy commuter with a perchance for attacking any and all singletrack connector trails in between with a vengeance.
