The Hammer Gravel Steel is our most versatile frame in our lineup. We took everything we learned from years of racing and riding our Aluminum Gravel frames and applied it to the quality ride and feel of Steel.
We selected our favorite mix of heat treated thin wall Columbus steel mixed with our die formed and custom butted signature profiles to make a gravel frame with all the stiffness in the right places while keeping the silky ride that steel is known for.
Build it as a gravel racer, all road rig, light tourer or super commuter. Custom geometry mixed with a tunable tubing selection lets us adapt this platform to your needs.
Our asymmetric rear end keeps your sprints lively, while our formed and butted Steel tubing allows us to tune your frame to your riding style and desired use. Our use of digital fabrication technology is as important as the hands that make your frame.
From Road To Gravel, And Everything In Between
Looking for an All Road rig? A Gravel Bike? A Cyclocross machine? A Gravel Racer? A Light Tourer? The Gravel Steel can be manufactured to your spec, with tweaks in material and geometry, your frame can hit all of the right marks for you and your needs.
3D Printed Dropouts
Our dropouts are minimal, lightweight, and versatile. We designed them to keep your frame future proof and crash resistant. With the use of a replaceable UDH hanger system, you can never ruin your frame by bending your derailleur hanger or cross threading your axle. You can simply install a replacement and get back on the road.
Premium Tubing
Mix of Columbus and seamless 4130 Steel tubing, butted and die formed in house to your specifications.
Tuned Ride
Our ability to cut, form, and weld in house, coupled with our wide range of tubing with varying wall thicknesses and butting profiles allows us to tune our frames based on your size, weight, and riding style. From sprinters to climbers and everything in between, we have you covered.
Custom Geometry
We offer custom geo to our customers for the perfect fit. Fill out our fit form, or we will partner with your local fit studio.
Make It Your Own
Each frame we build is designed specifically for you. Our tube selections and geometry create endless combinations, and when it comes to finishing, no two paint jobs are the same. Your bike is a one of one machine. We will work with you to help bring your dream bike to life.
