Calfee partners with Ellsworth to develop the ‘Witness’

Carbon full suspension tandem with Ellsworth rear end

Carbon frame builder Calfee Design has partnered with veteran full suspension manufacturer Ellsworth to develop the Witness, a carbon tandem.


The Witness features the wrapped carbon tube construction that Calfee is known for paired with a 140mm travel Ellsworth rear end. This off-road tamdem was developed around 27.5in wheels and will retail for US$8,295. Claimed frame weight for the Witness is 4.76kg/10.5lb.

Calfee can also build the Witness around 29in wheels for a US$500 upcharge. The 29in version gets a reduction in rear suspension travel to 120mm.
