Soma

Soma Fabrications, which gets its name from the San Francisco name of South of Market Street has become a favorite bike brand among those of us who want to build our own bike with high quality reasonably priced parts.

We love how Soma Steel frames ride. Rider after rider tell us how no matter how many higher end bikes they have in their garage, they always grab their Soma when they go out on their favorite rides.

We love their beautifully simple paint jobs, minimalist graphics, and more importantly the flexibility that their frames provide

We love them so much that we build up a number of Custom Soma Bikes that are high end commuter bikes, thoughtfully made touring bikes, cyclocross bikes and belt drive bikes that make our souls purr.

Soma Wolverine v3 Gravelo 650b or 700c
$1,875.00 - $2,525.00
Think of the Wolverine Gravelo as an off-pavement randonneur, a 700c or 650b (your choice) 2 x 10 build that we've optimized for adventures far from pavement, where the deer and the antelope play in the middle of the road, just like you. There's a higher-level Gravelo, which we call the Powerplant build. It includes a Shutter Precision dynamo hub, a Busch & Mueller Luxos U front light that charges your phone or external battery, and a Busch & Mueller tail light (your choice depending on mounting position). If you do go with a dynamo hub, we suggest the 650b build in order to get current to your lights at lower speed. The Gravelo joins our other Soma Wolverine builds: the Daily Grinder city build and the Weltgrinder Rohloff touring build. We'll post pictures of the 650b build soon.

Soma B-Side 27.5-inch (650b) Frame
$489.99
