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.

We've done hundreds of Wolverine custom builds in the past 5 years. Let's talk about yours--drop us a line or give us a shout. The original inspiration for the Wolverine was “monster cross”, but it is seriously so much more. Its geometry is stable enough for off road touring, but sporty enough for all-around adventure. With its sliding dropouts, you can turn it into a single-speed CX bike. With a split seatstay, it is compatible with the Gates Carbon Belt Drive. The primary differences between the V3 and V4 Type-B is that the latter has a third set of bottle bosses plus additional stack height on most sizes.There's also a new size, 46 cm. Wolverine v.4 Type A is not belt-compatible. See chart for their differences. The Type-A also adopts modern standards such as 142mm rear thru-axle and a 44mm headtube that will fit 1-1/8 straight steerer or tapered steerer with the proper headset type. There is NO frame break for Belt-Drive like the B-Type has.
