The Hammer Gravel Steel Plus is one of the most versatile framesets in our lineup - with increased clearance of 700 x 55c, a custom blend of butted and bent tubes optimized for adaptability, and a low slung off-road geometry meticulously designed to keep you in control of your ride. Borrowing specifications from our Gravel Ti Plus, we have maintained the speed and agility of our tested Gravel geometry and reproduced it in the most classic of all bicycle materials: Steel.
The Gravel Steel Plus boasts category-leading tire clearance combined with steel - the tried and true workhorse material. Our meticulously selected combination of lightweight tubing and custom 3D-printed parts comes together to complete the ultimate off-road machine. Strength and longevity no matter what you throw at it, the Steel Plus keeps you going when the road runs out, all without breaking the bank.
Options for 4 bottle cage mounts, frame bags, and rack/fender compatibility make this frame thrive as a gravel racer, all road rig, cross-country tourer or super commuter. Custom geometry mixed with a tunable tubing selection lets us adapt this platform to all your needs.
Tuned For Trails
Designed as a complete system, not just a frameset, the Gravel Steel Plus does exactly what you want it to with each pedalstroke. Long chainstays, a slack headtube, and wider tires give you the confidence you want to lean into those fast corners on loose gravel descents, and plush comfort that encourages you to stay in the saddle longer.
3D Printed Dropouts
Minimal, lightweight, and versatile. Designed to keep your frame future proof and crash resistant. Using a replaceable UDH system, bent hangers and crossed threads are no longer an issue.
Columbus Tubing
Built using a finely measured blend of Columbus thin wall tubing with custom die formed and butted profiles to create that signature steel ride feel. Our frames boast a stiff rear triangle that feels tight and responsive without sacrificing weight, and a precision engineered geometry to put you right where you want to be.
Internal Routing
Available with state-of-the-art full internal cabling for a seamless look throughout. Utilizing the Enve In-Route system, full internal cabling keeps your machine free of clutter, whilst not sacrificing ease of service.
Custom Geometry
Custom Geometry ensures a perfect fit. Fill out our fit form in person or remotely, or we can partner with your preferred fit studio.

Make It Your Own
Creating a precision machine tuned exactly to its rider’s specifications is what gets us up in the morning. Each frame we build is designed specifically for you with dedicated attention throughout each step of the design, fabrication, finishing, and build process. Your bike is a one of one machine.
