Whether it’s gravel, tarmac or any other surface. The Sputnik Kosmos feels at home both on as off the road. We measure, design, build and assemble from scratch because every rider has its own perfect fit. The geometry is made to fit the owner’s riding style and is built by hand to last a lifetime.

You will be able to keep an eye on the production process of your Kosmos. Orders are limited to keep the quality and service high.

It’s a hell of a ride.



  • Frame

    Made to measure with custom geometry

    Made to your body only. It's a unique experience to really feel one with your bike. This only happens when your bike fits like a glove. So we offer a bikefitting session from our partner Pedaalkracht. Once we've got your position right, we will built your perfect Sputnik frame geometry.

    Carefully selected tubing from Columbus and Dedacciai combined with an in-house produced head tube, thru-axle dropouts, custom bent seat stays and St Joris' (flat mount) disc brake mount make for a rock solid frame to endure your adventures.

    Details count. To give the bike that clean and sleek look, we go the extra mile to put your hydraulics fully internal. This makes your bike safe and reliably shielded from external impacts. Oh, and it helps when cleaning your bike after a rugged ride.

  • Fork

    Columbus Futura Gravel

    A Sputnik comes with a stable fork made by Columbus: the Futura Gravel fork with internal hydro routing and flatmount discbrake mounts.

    Optional upgrade: ENVE G-series gravel fork.

  • Headset

    Chris King limited edition

    No concessions made. A Sputnik comes with a headset that matches the lifetime of the frame: Chris King Inset in limited edition 'Matte Turqoise'.

  • Bottom bracket


    No pressfit for Sputnik. It comes standard with a T47 bottom bracket. A game changer, oversized and creak-free due to its 47 mm threads.

  • Groupset

    SRAM Force Hydro Disc

    Your Sputnik originally comes with a SRAM Force 1 CX Hydro Disc groupset. For the KOSMOS, we also introduce the Sputnik II version, equipped with the SRAM Force 22 Hydro Disc groupset. If 1x11 is your choice, it comes with a 42 chainring. If you are opting for double chainrings, then choose from 34/50 or 36/46.

  • Wheelset

    Handbuilt: Stan's Notubes Grail rims and DT240S hubset

    A Sputnik comes with nothing less than a handbuilt wheelset: reliable DT240S hubs (black edition) laced onto tubeless ready Stan's Notubes Grail rims with an allround 22.5mm internal width, perfect for allround use and gravel riding. You can perfectly mount tires up to 38 mm, but this rim also takes road tires down to 25 mm.

    Optional upgrades: Scope R3 or Scope O2 rims, Chris King R45 Matte Turqoise hubs.

  • Cockpit & Seatpost

    Deda Zero 100 kit

    We have different build kits to choose from. An understated DEDA ZERO 100 kit, either with regular road drop bars or with gravel specific 6-degree flare drop bars. If you like bold and timeless design, there is the black Thomson Elite stem & seatpost (zero setback) kit with Cinelli Dynamo black edition drop bars. Or when you want lightweight, go ENVE!

  • Saddle

    Fizik R3/M3 series or choose your favorite

    As a standard feature, we offer a Fizik R3 or M3 series saddle with your Sputnik Kosmos. But since saddles are as personal as frame fit and geometry, just name us your favorite saddle. The bikefitting session can also help you find the saddle that fits you best.

  • Tires

    Panaracer Gravel King SK Tubeless

    Your Sputnik Kosmos comes with tubeless ready Panaracer Gravel King SK tires in 35 mm width. This tyre has a gravel specific thread pattern en rolls well and with very little noise on tarmac. They deliver good grip on most off-road surfaces while having a low wear rate. They are installed tubeless or with inner tubes - your choice.
