Soma Fabrications Double Cross Disc Frameset

This bike is a phenomenal do it all bike.  I ride one myself.  I’ve ridden it on club rides, off road MTB rides, and bike packing tours.  It’s so comfortable and stable.  Here’s mine in a custom colourway:

PLEASE NOTE: The fork for this bike is automatically included when you add the frame to the basket. It is currently £185 extra.  If you do not wish to include this fork, please delete it from the basket before going to checkout.

 

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.

– 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 forks: Matching lugged and curved blade or black straight blade unicrown Tange Infinity CrMo steel fork; the lugged fork has double eyelets at fork ends and low rider rack braze-ons

  • What if I want to put 650b wheels on my Double Cross Disc?

    Doing a 650b conversion can be a fun experiment. People do it for the ability to run wider tires with fenders, to run those nice supple randonneur tires, to reduce toe overlap, to lower the bike’s bottom bracket height or just for curiosity-sake.

    The main concern when changing your tire size is how the ride will be affected. Generally you’ll notice only slight differences if at all.

    – The front trail difference is negligible: about 2-3mm less. So steering shouldn’t be affected.

    – The bottom bracket height(BBH) is the biggest change: With 700cx 32 tires your bottom bracket height is about 277mm. With 650b x 42 tires, BBH = 269mm With 650b x 33 tires, BBH = 265mm. 265mm is about the BBH of a race bike, so stability and cornering theoretically will improve, plus there’s no worry of pedal strike, since BBH is not at touring bike height yet. But BBH will be lower than what is generally recommended for CX or aggressive trail riding. Cruising fire roads and open gravel trails is still doable, but please test your conversion out in a safe controlled manner.

    – The reduced front tire/toe overlap is nice to have, especially on frames 54cm and smaller.

    – Please note that JUST switching to 650b tires does not make your bike handle like a traditional randonneuring bike. The tubing specs on randonneuring bikes like our Grand Randonneur is significantly different than on the Double Cross Disc. You would need a low trail / high rake fork to make your bike more front load-friendly, if that is a goal. Otherwise the conversion should yield a great bike for touring or fast commuting.

    The Double Cross Disc does not fit any knobbies wider than 45mm/1.75″.

Reviews:

Spokehaven’s Long Term Review of the Double Cross (this review is for the canti brake model)

The bike rides really smooth and is extremely comfortable on long rides. The bike is a little on the heavy side. Mostly because the wheel set is a very sturdy 32hole build with a 24mm wide rim. The wider rims are nice for putting fatty tires on. I’d like to experiment with the new Soma Cazadero tires on it at some point, but I will probably wait for the weather to turn before swapping tires out.

I also have all alloy parts and absolutely no carbon on the bike. I do see the potential in the frame for being a good, comfortable cross racer. Throw a carbon fork, bars, seat post, and carbon railed saddle on the bike and it would ride like the wind. Currently I own an aluminum Raleigh cross bike, but it’s not the most comfortable thing to ride on weather beaten roads. Steel may not be the lightest material in the world, but it sure is a lot more forgiving!

Soma has done a fantastic job on their overall bike line up and the Double Cross is no exception. I get tons of compliments on the bike and the color of the frame. The pearly blue is extremely classy looking and the powder coat has held up incredibly well. The logos and the frame badge are also gorgeous. Color me in love with the bike and the Double Cross frame. I should note that the newest color of the bike is more of a gunmetal-ish grey, but still very beautiful.

If anyone reading this is debating between the Surly Cross Check and the Soma Double Cross, I would highly recommend considering the Soma. It does has a taller head tube on it which means it’s not as aggressive, but for the price I think it’s just a slightly nicer frame. That’s not to say I’m not down with Surly. I love them as well and would buy a dirt tourer or one of their many cool fat bikes, but I just love the Double Cross more if doing a straight comparison. One other major plus, for me, is the fact that Soma uses vertical drop outs and not horizontal drop outs. I know why Surly uses horizontal dropouts and it makes for a more versatile frame, but they can be a pain in the ass when changing a rear flat. I also used to have issues with the wheel pulling to one side no matter how tight the rear skewer was on the Cross Check. I haven’t dealt with that what so ever on the Double Cross.

A Favorite of MTB29.com (for Double Cross DC)

Overall I’d say this is one of my favorite bikes to ride, especially when I just feel like going out and getting some excercise. Unless I’m going for a group road road, I’ll usually opt for the Soma DC over my fancy carbon road bike. This bike is the ultimate for going out cruising on back roads, hitting some dirt and getting in a good workout. I’ve done four and five hour training rides on it with lots of climbing and come home feeling fresh. For the full review click here.
