This funtastic machine goes out to my man Johannes! Jo came a couple of years ago as one of our very first customers and became a good friend and part of the Fern & Gramm family. This joyful tool is the perfect counterpart to his more classic Fern randonneur bike and will open up new oportunities for really serious offroad riding off the grid. Razorblade sharp handling with our sisterbrands Allygn M.U.D. fork, we designed and engineered ourselfes here at the Fern workshop. Allygn headset and our brandnew Allygn diamond front rack will be available soon! Check out Allygn.de for more infos!
Complete Gramm Tourpacking set of bags for multi day self supported riding.
The bike is equipped with the new Shimano GRX 1x11 group, superlight post and seat by Tune, power supply by SON. Running super smooth on 650B 55mm Conti Speedkings mounted on superlight Stan's Crest rims, this beast goes really fast!
Nice vintage touch with our trademark custom anodized Dura Ace crankset which provides an extremly narrow q-faktor of only 140mm with 60mm tires clearance! No drop down chainstays needed thanks to our perfectly bend and shaped custom chainstays which are made just for us by the incredible people at Columbus!
Amazing Scapin inspired colourway made by our man Rob at Velocio.com
Jo,...I can already see you happy bunny hopping through the Brandenburg forests! Hope we'll share some miles riding together on our Chucks in the next years! ;)
