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.
We do not recommend using 650b MTB knobbies yet, since at time or writing, there is not a model that is narrow enough to offer a safe amount of clearance. (Dated: 4-10-14)

Double Cross Disc
The search narrowed the candidates to Salsa, Surly and Soma. While the Surly Long Haul Disc Trucker is a champion tourer, the geometry is too touring for my liking, and I didn't really like the looks. The Salsa Doublecheck is a strong candidate, but I didn't like the fact that Salsa would not divulge what kind of tubes they use to make the frame. Whilst, Soma proudly proclaims the tubing is Tange Prestige, double butted. While welding is done in Taiwan, as is the Tange factory now, I understand, I find the welds flawless and the paintwork very nice indeed. Not Baum, or even Pegoretti nice of course, but nice enough.
How does it ride? My first ride out with the Soma, I couldn't wipe the grin off my face. The ride was ultra smooth. The bike was not as stiff, or fast as the Baum Coretto, a bike already featured in these pages, and cost 5 times more than the Soma. Though the Baum is titanium and the Soma steel, I find the Soma ride to be smoother. The White Industries hubs were also very smooth...as butter...albeit a lot more quiet than the Tune on the Baum. Now, coasting on the bike will not warn pedestrians ahead that a bike is coming...the Tune is very loud and one can do without a bell on the PCNs.

This frame is underrated. People always rave about the [popular similar frame model we won't name]. Sure it's a great bike and what not, but I've ridden both and I like the DC better. Slightly lighter frame. Higher quality steel. Note I put on some 700x25c tires on them for my 15 mile crappy/rainy Seattle commute. For a steel bike, It's pretty quick and responsive. I don't even try to avoid potholes and rocks.

Unsolicited Soma Double Cross DC Review
Its been said that a great bike is a bike you want to ride everyday. The Soma Double Cross [DC] scores a 10 out of 10 on that basis. My initial impression on the bike was how big, but comfortable the fit is.... I’m on the drops about 50% of the time, the hoods are easy to ride and the cross bar is good to use at lower speeds and helps me look above the traffic as I commute. The very tall 195mm head-tube is golden. It puts the handlebar at just the right level without multiple spacers. It looks right, and the fit is great. The ride quality is remarkable. It provides a smooth comfortable ride as the rider seems to float along. I was looking for long distance traveling comfort and the steel frame with a carbon fiber fork is very damp and plush. The bike also feels lively and accelerates well. I can sprint to 25 mph at will. Handling is excellent and stability is also very good. The bike turns in quickly without feeling squirrelly. Stability is more than adequate. The bike will drift off line if the rider is daydreaming, but no issue IMO. It’s the kind of bike that wants to be driven hard at 20 mph or more. -- (This testimony is of a Double DC, an older that had canti bosses and disc mounts. Geometry and tubing was the same as this model)

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.
Double Cross DC Review in Bicycle Times
"Coming off of a stiff aluminum bike, the Tange steel felt great. The ride quality of the steel was quickly apparent as it dampened just enough of the road chatter to smooth out my commute. Although the steel dampens vibrations the frame is responsive and quick, transferring my energy to the wheels and not side-to-side." For the complete review go here.
