Soma Rush Fixed Gear With Belt Drive

When a local customer contacted us about building a belt drive-equipped fixed gear for him, we were excited to execute his vision. He wanted a bike that would be simple, lightweight, and durable for commuting around town quickly. He gave us a few general guidelines for the build but asked us to make our own recommendations for parts that would fulfill his requirements. His primary requests were that the frame be chrome colored and that he could use a belt drive system. He planned to use the bike to zip around Oakland and commute across town to work - primarily short, fast rides without much climbing.

Black Sheep High Light Titanium Belt Drive Single Speed with FaithTruss Fork

This beautiful titanium bike from Black Sheep Bikes in Ft. Collins, CO came into the Monkey Lab for a Gates Carbon Drive belt conversion. While we are known best for our Rohloff Internal Gear Hub builds, we're big proponents of the Gates belt drive system, which is a fantastic option for single speed bikes as well as internal gear hub bikes. With Black Sheep's signature curved tubes, this bike is an exquisite example of the kind of creative fabrications that can be achieved by small custom frame builders. The whole bike weighs in at only 21 pounds but feels even lighter due to it's super light EDGE (now ENVE) carbon rims.

REVIEW: Soma Sandworm Fatbike with Rohloff SPEEDHUB and Gates Carbon Drive Belt
Soma Fabrications called us recently and told us they were designing their first fatbike frame named the Sandworm; they wanted us to test out the prototype and give it the Rohloff SPEEDHUB 500/14 internal gear hub and Gates Carbon Drive belt drive treatment that we are known for. We were glad to hear they had decided to expand into fatbikes with this frame and potentially bring the fun of fatbiking to more people by filling a hole in the market for an affordable Rohloff/belt drive frame. Once we received the frame, we began mapping out a build kit suitable for this project.

Merlin Roots Mountain Bike with Rohloff SPEEDHUB
This Merlin Roots came in to the Monkey Lab for routine service, and we were excited to check it out. Offered as a limited edition, the frame is modeled after the original west coast "Klunkers," the home-made dirt cruiser bikes that were ridden at breakneck speeds by the pioneers of mountain biking on the dirt roads and hiking trails of Marin County's Mount Tamalpais. Although the aesthetic of the bike is similar to early Klunkers, it's equipped with modern geometry, materials, and technology that didn't exist in the early days of mountain biking, including a Rohloff SPEEDHUB 500/14 and hydraulic disc brakes. This bike's owner was initially drawn to the bike because of its form, but his first few rides confirmed it is also an extremely functional ride.
