Duetti S1

Availability: Available for Special Order
Delivery time: 1- 2 weeks


Ben Serotta’s vision for ‘Project Duetti’ was to develop a forward-thinking machine optimized for 90% of the riding we do today, making it your go-to cycling companion. The top considerations were proportioned fit, versatility without compromise and incorporating a future-proof assembly that combines great performance, dependability, and value. 

A great bike fit is the result of both positioning the cyclist on the bike and positioning a well-proportioned bike underneath. Combined, the stage is set for a great day in the saddle with efficiency, endurance, comfort and confidence-inspiring handling. That’s why the Duetti S1 is produced in eleven distinct sizes (twice as many as most companies), offering every rider a true fit experience. 

This commitment to fit is what led Ben to select an exotic aluminum alloy for the main frame, rather than carbon, as it facilitates the greatest flexibility in manufacturing. Determined to create a bicycle that is light, responsive, comfortably smooth, reliably durable and a ride experience that rivals the best of any material, we had to go global. 

The rare 6069 alloy we use has very limited exclusive availability. Vanadium is the key ingredient, significantly boosting durability.  After welding and heat treatment, we added shot-peening, a process developed for military aircraft, further increasing lifespan by 300% or more.  Not surprisingly, we've partnered with the most experienced fabricator to handle Duetti’s construction.  

With no detail left unattended, Serotta’s international team of veteran American, German and Taiwanese engineers embarked on a tour de force effort, leveraging Ben’s "Colorado Concept" engineering principles, to ensure a sensational ride that warrants the Serotta signature.  

The hydraulic disc equipped Duetti is available in both mechanical and electronic shifting options from $3,695 to about $6,295.
