For those who demand a unique ride

Beautifully handcrafted from Columbus XCR stainless steel, the Extensor delivers a unique riding experience that sets it apart from anything else. Stiff and wonderfully responsive, it’s the bike that invites you to push.

With its seamless construction rather than welded, XCR tubing was chosen above other stainless-steel tubes for the Extensor. With tube wall thickness down to 0.4mm, the XCR tube set has a higher stiffness to weight ratio than aluminium or titanium.

With less ultimate compliance than a regular steel frame, the Extensor is stiff and very responsive. It invites you to push it to its limits, and so do we. Act out that same dream we had of extracting every ounce of performance, before distilling it into a design that we hope brings out the very best in you.

Every Extensor is custom built to order right here in our East Sussex workshop. Each build is customisable, with rim brake and disc brake options available that allow you to tailor a design just for you.
