Frames

Soma B-Side 650b MTB Frame

• Tange Prestige heat treated CrMo steel front triangle; butted CrMo rear end

• Geometry designed to accommodate a 100-120mm travel fork

• Int’l disc brake tabs (rear)

• Tange Stainless Steel Sliding Dropouts for geared or single speed set-ups

• Machined 44mm headtube (fits tapered steerer tubes using a ZS top assembly and 40.EC44 external cup lower assembly; fits 1-1/8” steerers using a ZS44 headset)

• Fiery Red

A true mixte frame with the double top tube/stays. Obviously offers lots of standover height and style as well. You’ll find the geometry is more sporty, than upright-comfy. Though it can be built up to suit either demeanor. Drop bars? Sure. Moustache bars? Of course.

The upgrade to fitting disc brakes opens this mixte to fitting many different widths of tires, so instead of being limited to 700c x 32mm road tires, you can experiment with a variety of gravel and touring tires as well.

The Fog Cutter is an endurance road/road sport design. We designed it to fit fatter tires, but its geometry makes it handle like a road bike rather than CX or gravel bike. It can float you over chewed up asphalt better than most bikes in this category. This is the frame you want for grand fondos, long days in the saddle and the most demanding commutes.

The Smoothie HP is the “high protein” version of our Smoothie road frame that was part of our line for almost 20 years.

Extra large diameter, thin-wall Tange Prestige chromoly coupled with modern touches like thru-axles and compact geometry give this frame increased power transfer and road feel while still delivering a composed and plush ride at all speeds.

The Grand Randonneur is a road frame optimized to carry a front load. We have equipped it with rear rack mounts, but it feels best with a front load only. The version 3 of the "Grando" makes quite a few updates.

• The geometry is still low trail in the front, but we have tried to make the handling slightly more stable than version 1 and 2.

• We have tweaked the tubing mix to add stiffness at the bottom bracket, while keeping this frame our lightest model.

• We have modernized parts of it: Adding IS disc mounts and thru-axle hubs compatibility. And of course everyone wants just slightly more tire clearance.

• With its skinny steel tubes and 1" threaded lugged crown fork it still has the vintage road bike look.

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.

The primary differences between the version 3.0 Wolverine and the v. 4 Type-A and B is an extra set of water bottle bosses, and additional stack height on most sizes.

The Type-A ALSO adopts more 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. NO frame break for Belt-Drive. (See chart for other differences between A and B)

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 4.0 and 4.1 is that the frame and forks now fit the flat mount brake standard.
