Valentine’s day is quickly approaching and this year Calfee thinks you should skip the tired flowers and chocolate. Instead, why not a custom carbon fiber mountain tandem complete with Ellsworth ICT suspension? Okay, if you show up on the 14th with another bike we can’t guarantee the rest of your evening, but if you’ve been looking for a new tandem that is supremely capable of tackling your off road adventures, the new Calfee Witness is worth a look. By combining Calfee’s decades of experience building tandems and carbon bikes and Ellsworth’s 25 years of MTB geometry and suspension knowledge, the two collaborated to produce the Witness – a 27.5 or 29″ wheeled custom tandem.
Think your relationship could survive the Witness? Check out the details below.
While the main frame of the Witness is 100% Calfee built, the rear end of the tandem is sourced from Ellsworth’s patented ICT four bar linkage design. If you want an in depth break down on Instant Center Tracking, it’s probably best to head over to Ellsworth’s website and hear it straight from the source. Just know that the ICT design works quite well, offering a fully active suspension system that is very energy efficient.
Offered as a frame only, the Witness starts at $8,295 for the 27.5″ frame and is an additional $500 for a 29er. Each frame is built with a 14.5″ bottom bracket height and 42.5cm chainstays. The frame uses internal cable routing which is compatible with mechanical or electronic drivetrains. Witnesses will be available in 5 sizes based on the size of the captain and the stoker – just keep in mind these numbers are based on the 27.5″ bike with a 2.25″ tire.
