Hammer Road SL

We are putting our aluminum frame production on hold indefinitely to make space for new projects. Stay tuned we have some rad stuff cooking! 👽

The Hammer Road SL is a zero compromise frame designed for the modern road rider. The combined qualities of aerospace grade aluminum and carbon fiber create an unparalleled ride that is fast and aggressive but also comfortable for long days in the saddle.

This frame has the best of both worlds, it has the lively feel, stiffness and reliability of an aluminum bike with the weight savings and vibration dampening of carbon fiber. The result is our top of the line ride with cutting edge materials and technologies that is handmade to size just for you. 

From top to bottom we reconsidered what a modern road bike can be. We designed the Hammer SL to have clearance for 32c tires for fast rolling comfort and traction on rough roads as well as compact geometry and thru axle flat mount disc dropouts that give you a solid and confident platform for sprints and steep descents.

The Hammer SL features a full carbon fiber seat mast that saves weight while improving the road feel by absorbing small bumps and vibrations. We worked with the engineers at Enve Composites where they make each carbon tube custom to our specifications. 

Our CNC dropouts, bottom brackets, head tubes and seat mast topper have been reconsidered and fully optimized for light weight and performance. The result is increased stiffness, braking power and overall ride quality while cutting weight. 

Integrated Seat Mast

Our custom molded carbon fiber seat mast gives the best of both worlds, a trusty metal bike with the lightweight and dampened ride quality of carbon. Lightweight, fast and comfortable.

Machined Dropouts

Our in house designed dropouts are minimal, lightweight and versatile. We designed them to keep your frame future proof and crash resistant. With the use of a replaceable hanger system and syntace inserts 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.

Custom Geometry

We offer custom geo to our customers for the perfect fit. Download and fill out our fit sheet, or we will partner with your local fit studio.

Internal Routing

All cables, hoses and wires live inside your frame away from dirt and grime keeping that shifting crisp and maintenance to a minimum.

Tuned Ride

Our wide range of tubing with varying wall thicknesses and butting profiles allows us to tune our frames based on a riders size, weight and riding style. From sprinters to climbers and everything in between, we have you covered.

Make It Your Own

Each frame we build is designed specifically for the customer. We do not duplicate paint jobs, so your bike is one of one. We will work with you to help bring your dream bike to life.
