Sanitas Cycles is a company that has a combined 60+ years of experience in the cycling industry. One of the Co-Founders, John Siegrist founded DEAN Titanium Bikes in the 80s. He has built custom bikes, for the likes of Merlin Metal Works, Ibis cycles, EverTi, Form, Haley, Ionic, Sampson, Jade, Stoemper, Red Tail, and VYNL… just to name a few.

The Root Classic is an individually handcrafted hardtail that is built with oversized cold work 3/2.5 titanium tubing. Each of the frames is custom-built to the customer’s specifications, one at a time. Resulting in a bike that is designed with the customer’s needs and riding style in mind.

Designing the Root Classic to ride smoothly over all types of terrain, the frame was built with features like the signature “s-bend” chainstays and seat stays, as well as stress-relieved titanium tubing. Stating that the Root delivers nimble handling while still offering “exceptional climbing and descending ability”.

They also say that they have a multitude of frame finish options as well as anodization by Agave Frame Finishing for an upcharge.
