Shimano’s Di2 electronic shifting system continues to make it’s influence felt across the road sector, providing builders a challenge to accommodate the new technology. Portland’s Het Fairwheel Podium recently explored the possibilities of applying the system to mountain bikes, with astounding results.
This is a Titus 29er frame, assembled with the cream of current MTB components. That ENVE stem contains a chip which enables sequential shifting. It’s programmed to provide the next most efficient gear depending on chain position. Only one shifter is required providing, in essence, a ‘more-or-less’ changing procedure. The rest of the build is a perfect complement to the technology. A Cannondale Lefty fork up front, ENVE stem and bars and KCNC levers which pull up a pedigree wheelset: Tune hubs and ENVE tubulars shod in Dugast rubber. KCNC also provided the cranks, ceramic headset, seat post and collar, pedals and grips. The claimed weight is around 7.3kg.
