Our Soma Saga is built for amazing voyages short and long. Because this bike is built in-store you get serious componentry and boutique flare you wont find on off-the-shelf bikes. The Shimano Sora groupset offers excellent adaptability on the road and the trails. Legendary Panaracer gravel king tyres in green by Sim-Works. Plush Fi:zik carbon braided Aliente saddle. Shimano pedals you can ride clipped or not plus many more hidden details. Amazing specs for this one of a kind build.



  • Specially chosen Tange Prestige heat-treated CrMo tubing; 31.8mm butted downtube and top tube for a stiffer front triangle. Larger frames have slightly thicker gauge tubing. Bombproof headtube is nearly impossible to ovalize.
  • Longer chainstays and lower BB add stability and keep the panniers out of the way of your heels. Geometry puts the rider in a semi-upright position that is better for all-day riding.
  • Disc brake specific dropouts work with ISO mount caliper. Rear brake mounts on the chainstay, so it doesn’t interfere with rear rack or fender mounting. The dropout also has a port for Rohloff OEM2 mounting.
  • Compatible also with cantilever brakes and linear pull brakes. (Posts are removable)
  • Matching flat crown fork has double eyelets at the dropouts, as well as low-rider mid-leg pannier mounts, and mini rack eyelets. It is reinforced to handle disc brake forces.
  • Spoke holder, pump peg, flat chainstay plate (fits some double kickstands), and three sets of bosses round out the full touring spec
  • Sizes: 46, 49, 52, 54, 56, 58, 61, and 66cm. (Size not determined by seat tube length)
  • Weight: 5.75 lbs (49cm frame); 2.7 lbs. (fork, with uncut 350mm steerer)
  • Paint: Cobalt Blue

Why did you include both disc and canti brake mounts? Doesn’t it make the bike look cluttered?

Let’s address the aesthetic issue: If you are afraid of a wee little clutter, loaded touring is not for you. A bike loaded up for a tour is not supposed to look “clean” — and that’s a wonderful thing. Once you install racks and bottle cages, you’ll hardly notice the extra mounts. When you add panniers, frame bags and water bottles, those extra mounts are pretty much invisible. So in the greater scheme of things, we don’t think it makes the bike look more cluttered AT ALL.

There are also a few benefits to having provisions for both brake styles. 1. While both disc and rim brake technologies are generally reliable, we have known cyclists who have had bad experiences in the middle of a tour with cantilever brakes and vowed to to get discs on their next bike AND cyclists who had nightmares with their discs brakes in the middle of a tour and vow “never again” and want to go back to rim brakes. Having a Saga DC allows you to make the brake switch without the headache of buying a new frame.

2. Even if you don’t suffer an unforgettable mechanical in the middle of nowhere, we all change our minds sometimes. You may love the idea of discs, but discover after 2000 miles you can’t stand the pad/rotor rubbing you can’t seem to get rid of..

3. You have old parts! What if you want disc brakes, but have an old Nitto front rack that mounts to cantilever bosses. You can use both that classic rack and your modern disc brakes on the Saga DC.

4. If you ever choose to sell your Saga DC, you can attract traditional customers who like rim brakes and those who want disc brakes.

5. “Redundancy” Having a back up is generally an advantage while on tour. This is one bike where you could install two front and rear brakes. Just install cross levers and route them to your rim brakes. You have to be really really worried about things breaking down to do it, but hey we got you covered. (We do discourage anyone from trying to activate all four brakes at once though)

Are the cantilever bosses removable?

The posts where the brakes rest on are removable. We recommend protecting the threads of the brake mount from nature with grease, Boeshield or a cover if you are not using are removing your posts. The painted brazed on piece is not removable.

How is sizing determined? Do you use seat tube length?

The “size” is not based upon seat tube length. Actual seat tube length is in parentheses on the geometry chart. Industry folks call this “virtual sizing”. Effective top tube length, stack and reach are better size indicators. If you don’t know your ideal size, please get sized by a professional bike shop.

Can I sit on my bike while the kickstand is engaged?

This is not really an frequently asked query, but it is important to address. We welded a kickstand plate between the chainstays to make it easier to mount a double kickstand, which is really handy when your bike is loaded up. It is strong for what is supposed to do, but it is not suppose to hold up the bike’s weight and your weight. (So no, no, no!) The kickstand or the plate will break if you sit on your bike while the stand is engaged.. Also be sure to trim the legs so weight is evenly distributed on the tires and the kickstand. If you can’t get both tires flat on the ground, at least get the rear tire down (especially if you are loading luggage in the back)

Do the wheel sizes vary with frame sizes? If so, how was the standover height determined?

Some sizes are made for 26″ wheels, others are made for 700c. Please look at the geometry chart for breakdown. Standover is determined using a 26×1.5″ tire or 700cx32c tire.

“Compared to the other frames in it’s class, the Surly Long Haul Trucker, and the Salsa Vaya, I still think the Soma Saga comes out on top.”

My Soma Saga touring bike sporting a new set of shiny fenders and new leather saddle. I could have at least wiped the mud off the chain stay!

With 4 tours covering a good deal of Oregon and Washington, 3 years of commuting all winter, plus numerous overnight tours and day rides, the Soma Saga has been a solid, dependable, and fun ride. This page has the original specs and a picture when it was new. I think I did the first two tours with the Jandd Extreme front rack, but then opted for the Tubus Tara low rider. I’ve changed the saddle a few times, most recently to a Selle Anatomica X series. The original set of Schwalbe Marathon Plus tires got 6,500 miles without a flat. I swapped them out for a set of Schwalbe Marathon Supreme tires which are still going strong with no flats. The most recent addition has been a set of Velo Orange hammered aluminum fenders, which really added some class.

Soma Saga frame and fork

The frame itself is all I could ask for. Of course it feels solid, but it handles quite well with or without a load. And it does like a load. When I’m not touring I sometimes put on both sets of panniers and go grocery shopping, loading it up much heavier than when I tour. When I do it always feels great, like it was really made for a heavy load. When touring I can bomb down hills with confidence. The steering is true and never sloppy. Bumps and irregular pavement jolts are absorbed nicely by the steel frame. On smooth level roads I can ride this bike hands free much easier than my other bikes, even with a load in the front. The paint looks new after 3 years with only a couple of little dings where it got banged around in bike racks. The kickstand plate has worked out wonderfully with my Pletscher double leg kick stand. Compared to the other frames in it’s class, the Surly Long Haul Trucker, and the Salsa Vaya, I still think the Soma Saga comes out on top. There is no question that I am very happy with it.


If you’re looking for a first rate touring bike you would be hard pressed to find a better frame than the Soma Saga. Soma now sells the Saga as a frame and fork only, or as a complete bike with a decent build. Although I have 3 bikes that I ride a lot, the Saga is the one I choose for everyday riding and touring. And now that it is well broken in the only thing left is to get out for a much longer tour, which I plan to be doing very soon.

Practical, durable, comfortable, affordable, customised bicycles for the everyday cyclist… these are the primary forces shaping Soma’s ideology.
