Hammer Gravel 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! 👽
Enjoy riding fast on or off road with the Hammer Gravel SL. It is the fast, fun and dirty evolution of our Hammer line. We are bringing the same DNA of our road and track machines to the rough roads.
This frameset is a result of over 2 years of development and testing, we took a deep dive into designing every feature on this machine. We used our asymmetrical Weistec drive side for the stiff and responsive sprints our frames are known for. Our updated T47 bottom bracket is lighter and allows for full internal cable routing for clean lines and grime free shifting. We also redesigned our dropouts for improved shifting, lighter weight and more confident braking.
Our custom Enve Composites carbon fiber seat mast absorbs vibrations and keeps you locked into your saddle when you are racing the dirt roads or dodging potholes. To top it all off we used the trusty Enve seat guts for our superlight ISP seat topper for a slip free and low profile system. This 7000 series aluminum and carbon fiber frameset is designed for long fast gravel roads, punchy climbs and technical descents on multi surface terrain.
We built in a CNC yoke to keep the rear end tight while making room for 700c x 45 and 650b x 2.1” tires. Short chainstays and big clearances keep your ride agile while giving the option for technical riding and grip in tough terrain. Throw some slicks on it and you have an unstoppable city shredder.
We designed our CNC yoke for BIG tires and ample chainring clearance. This 4 axis machined piece is super light, stiff and keeps the rear end short, tyte and agile.
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.
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.
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.
All cables, hoses and wires live inside your frame away from dirt and grime keeping that shifting crisp and maintenance to a minimum.
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.
