Ellsworth Aluminum

Ellsworth Aluminum bike frames provide all the excitement, function, and efficiency of our carbon fiber frames, but at a lower cost. We’re still making these in the USA, and we’re proud of it. Prior to being welded, each frame tube is milled by hand for a perfect, gap-free alignment with the other tubes as the frame is assembled in the jig. These tight joints ensure that the frames can be welded to perfection for maximum strength, stiffness, and durability. All of our aluminum frames are anodized to show off the flawless craftsmanship and to protect the aluminum alloy from corrosion, inside and out. Like our carbon production, you can be sure that our aluminum frames are made with the same social and environmental stewardship, and that are manufacturing practices minimize waste and raw material usage.
