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.

– Tange Prestige heat-treated CrMo steel main tubes

Cyclo-cross bikes like the early Double Cross frame were the ride-it-all bikes of their time allowing cyclists to use them as road bikes, light touring, off-roading, as well as in CX events.
With its advent and current stage of development, the gravel bike has become the new king of "ride-it-all".

With just a few changes in BB height and head tube angle, we made the Double Cross more stable for gravel and touring, more fun on trails, and still a versatile and fast commuter.

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

– Disc mount is located on the chainstay which allows you to put almost any rear rack or fender on it without fear of interference. Rear disc mount is International standard and fits 160mm rotors only

– Optional color matched fork: Straight blade unicrown fork with three bosses to allow for utility cage or pannier rack.

– Clearance for 700x45c tires (40c w/fenders. Some front derailleurs may reduce this clearance) We recommend 650b/27.5" wheels for 42cm size to reduce toe overlap with the front wheel.

– Rear hub spacing is 135mm (10mm axle QR hubs)

– 1-1/8" size headtube (for external cup headsets)

A great do-all frame. Ready for cyclo-cross, trail-riding, commuting and medium duty loaded touring. Comes in a wide range of sizes to fit you right -- up to 66cm! In 2017, we have increased tire clearance slightly and added stiffer, lighter dropouts. We are also adding an ED coating to the insides of our frames for long term protection against rust. Sizing has been tweaked on the five smallest sizes.

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 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.

• Tange Prestige CrMo tubes, double-butted

• Threaded 1" lugged crown fork is equipped with low rider pannier bosses, mini rack eyelets and double eyelets at the dropouts. Thru-axle hub compatible. IS disc mounts
