Co-Motion Klatch - Adventure Road Bike with Rohloff SPEEDHUB and Gates Belt

This bike started into motion when our customer in Burlingame, CA first rode his friend's Rohloff-equipped touring bike. He liked the internal gear hub so much he decided to design a bike of his own around the system. During his research into potential frame options, he found our Monkey Lab blog post about a previous Co-motion Klatch we built and got in touch with us to discuss building him something similar. He wanted a low-maintenance bike that was suitable for bike-packing, gravel rides, and mild single track. He knew the Rohloff SPEEDHUB 500/14 would meet his drivetrain needs perfectly, especially when combined with a Gates Carbon Drive belt, and he had a top shelf build kit in mind to finish off his dream bike. Once we had all the details in place, we got in touch with Co-motion to finalize the frame details and set out on making the bike happen.

Co-Motion Cycles is a company who specializes in building bikes for touring, commuting, and tandems at their factory in Eugene, Oregon. They are a prominent supplier of Rohloff bikes in the US, offering several complete touring bikes equipped with these high quality gear hubs.

The Klatch model is designed as a gravel road racer, but it is  also at home on daily commutes, long road rides, or bikepacking. With a Reynolds 853 tubeset, the Klatch frame is noticeably lighter than the touring models that Co-Motion specs the SPEEDHUB on and is categorized as one of their race-capable bikes. Stock geometry on the Klatch is more upright and stable than a road racing bike but is still nimble and quick enough for fast-paced pavement rides. Like all of Co-Motion's offerings, custom geometry is available upon request, which we took advantage of to dial in the fit for this customer.

Since the Klatch is normally sold with derailleurs, we worked with Co-Motion to make this Klatch both Rohloff SPEEDHUB- and Gates Carbon Drive belt-specific by adding a two-piece drive side dropout to get the belt into the rear triangle, Rohloff-specific cable guides for clean cable routing, an eccentric bottom bracket for tensioning the belt, and extra stout chain stays to prevent any flex in the drivetrain and ensure max belt performance.

Along with custom geometry, Co-Motion also offers an extensive selection of paint options applied at one of their in-house paint boothsThis customer chose their semi-custom "Pewter Grey" color with slices of “Sunrise” yellow on the inside of the chain stays and fork for added color accents. This paint job has tiny metallic particles embedded in the paint that reflect light and add depth and shine to the look of the frame. All these highlights and personalized details combined to make this bike just what he was looking for; a top-notch build with aesthetics that complement and represent this bike's quality at a glance.  

While the frame was being built, we got our Wheel House involved to build the ideal wheel set to match this Klatch's elegant style. Both wheels are laced to ENVE's tubeless compatible 29" XC MTB Clincher rims with Surly Knard 700c tires to take on the gravel in this bike's future.  In the front is a Chris King ISO Disk hub and bringing in the rear is the Rohloff SPEEDHUB 500/14 ready to get this Co-motion Klatch in the right gear. Sapim Laser spokes connect everything together and save some weight while adding a little ride comfort.

The Rohloff SPEEDHUB 500/14 is a great fit for an adventure road, gravel, and bikepacking bike. Its adjustment-free sealed shifting system will hold up just fine to rough riding. The SPEEDHUB provides dependability in all riding conditions, making it the perfect choice for a bike to take on a long journey down dirt or gravel roads. With the addition of the Gates Carbon Drive belt, which has a usable lifespan at least twice as long as a conventional chain (and typically much longer) and does not require lubrication, this is one of the most low maintenance and dependable drivetrains available. This set-up is perfect for a hassle-free ride every day of the week.

Between time of order and arrival of the frame, Gebla released their Rohbox ratchet box, which makes it possible to shift the SPEEDHUB using modified SRAM or Campagnolo shifters - either integrated drop bar brake/shift levers or flat bar trigger shifters. This was a welcomed development for this customer, allowing him to have finger tip shifting like he was used to on his road bike.  In this case, we used SRAM Rival shift levers and TRP Hy/Rd hydraulic/mechanical disk brakes to get nearly full-hydraulic brake performance while keeping setup easy with cables.

To complete this top-shelf build, the bike got carbon cranks, seatpost, and handlebar. A Sella Anatomica X series saddle provides comfort for long days on the bike, as does Lizard Skins thick DSP bar tape.

This customer wanted a top-notch adventure road bike fitted with components that would last and that looked as smooth as they would ride. With the help of Co-Motion, we were able to deliver exactly what he was looking for.

  1. Hi, This is a great build!

    Are both shifters used to shift the hub or just one?

    1. Both shifters are used, with each one shifting in a different direction.


    2. Both shifters are used, with each one shifting in a different direction.


  2. Oh I answered my own question, the Gebla Rohbox uses both shifters. Just like eTap. Awesome!!!
