This is bike is the essence of my understanding what a modern ultralight Fern randonneur bike should be like, bringing the overall weight of the fully equipped bike including a steel frame / fork / stem, frontrack, fenders, lights, pedals, etc... down to an incredible 9,4kg!
This machine features a mixed blend of the best old- and new school bike parts available, in order to create a ultralight but yet still robust and reliable machine for hardcore real world long distance brevet riding.
We cut no corners on this bike and even had made 650B prototype deep aero section tubeless compatible 30mm wide carbon rims with a braking surface!! Probably the only pair of such type rims existing on this planet right now ;) Combined with the superfast extralight 650B x 48mm Rene Herse Switchback tires and Sapim CX Ray aero spokes these wheels give you a perfect airfoil section for super low aerdynamic drag, but still providing a mega comfy ride which is very important for long distance cycling.
Superlight handmade carbon fenders by Veloduo combined with our own custom made AssSavers Bro and Toetectors for dry feet and buddies at all times.
We even build a ultralight custom aluminum version of our own brands Allygn Components Diamond rack. Series production models available in our online shop now!
Our friends at Tune helped us a little with some of the nicest and very light weight parts out there including handlebar, vintage NOS bobo headset, rear hub, bottle cages, seatpost and saddle which helped a lot to reduce the overall weight of this bike.
1x11 drivetrain with Gevenalle shifting a Ingrid components rear derailleur, custom anodized vintage Dura Ace crankset with Garabaruk chainring, Sram X-Dome 11-42 cassette and Extralite V-brakes.
Energy supply as usual by SON, lights from Busch and Müller with a customized 12V version of their IQ-X headlight which is powered via the Forumslader Pro for ultrabright illumination. The headlight can now be programmed via the headsetcap intergrated mini switch which also switches between different light modes, high and lowbeam. The custom made ultrasmall aluminum taillight houses the internals of a B&M Mü.
And if all that would not be enough, the bike is equipped with a full set of custom handmade superlight cuben fibre fabric randobags made by my love Kristin at Gramm Tourpacking. The bike features for the first time our brand new Gramm X Allygn Diamond bag which is the first aero shaped handlebar bag out there! The bag perfectly fits our Allyn Diamond rack and will be available at Gramm Tourpacking soon!
Supernice volcano and lava inspired ultramatte rubber softtouch paint with 80ties style 3D logos made as usual by our man Rob at Velociao .
"Rien ne ve plus", I would say! ;)
