    Soma Double Cross Sizing, 56 or 54?

    After reading a bunch of threads re: the question of Soma and CX sizing, I am still just as doubtful as ever. Maybe some of you can help dispel these doubts. I am 5'11.5", with a 33.25" inseam (barefoot, shoulder height apart), not sure how long my arms are, but my side to side reach is a bit over 6' (+1 ape index) so they are a tad longish. Don't own a roadbike currently, but my last was a 56cm C-Dale r5000 (56cm TT, c-c) which felt a tad cramped (don't remember stem length, something moderate no doubt). My hardtail mtb effective TT is 59.5, with a 110 stem, used to run a 150 just fine). Best fitting road bike I have owned was a Bianchi with a 57cm TT and a longish drop stem. Soma Double Cross geometry: size 56 = 576 effective TT, 31.9" standover, size 54 = 567 effective TT, 31.2" standover. Generally I like a longish cockpit so I am leaning towards 56cm. This is going to be my only "road" bike so I intend it to do everything from grocery getter, fireroads bikepacker (although I think I will get a trailer), to cross racer (looks horribly fun, I want to try it!). Never raced 'Cross (or anything for that matter) before so unsure what a racing cross fit is like anyway. Help!

    Hmmm, just rode a 54 Cannondale CAADX and it seemed short in the top tube. Could probably make it fit with a long stem. But at 54.5 TT for the C-dale, either size Soma would be significantly bigger.

    Are you kidding? I'm also 5'11.5", and I'm happy with my size 60 Double Cross.
    When I ride my bike I feel free and happy and strong. I'm liberated from the usual nonsense of day to day life. Solid, dependable, silent, my bike is my horse, my fighter jet, my island, my friend. Together we will conquer that hill and thereafter the world.

    Yeah, Barrettscv, I read your post before I wrote mine, but there are also guys our height riding 54's! I have little doubt a 60 would be too long, but maybe a 58 would work? I think I have ruled out the 54, but the top tubes are so long on the Soma! I actually like it, but since this is going to be ridden in the dirt a fair amount I don't want to go too big. I think a 56 will almost definately work, although maybe a 58 would too. I went through the competetive cyclist fit calculator and it says I need a 57.3-57.7 TT, which would be a 56 Double Cross. Anyway, getting excited about it. I think I will probably pull the trigger. Haven't had a bike with skinny tires in a couple years!

    I would not suggest a 60cm size. It fits me, but I use a compact handlebar and a 110mm stem. I would get a size 58 if I was to buy again.

    I don't fit bikes with 585mm VTT or less. I do like a streched-out fit.

    54cm would be too small for you, IMO. a 56cm should work if you like longer stems and regular reach handlebars.

    Cannondale's geo is a little weird. I'm a solid 5'10" and I ride a 54 on my CX-9 but it can feel a little small. Mine is a purpose built race machine so I don't spend a lot of time on it but it works for racing. It I was buying again I would go for the 56cm.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    I got my Double Cross a few months ago and it's a 54.... I'm 6'. I was skeptical at first but I'm liking it so far, it doesn't really feel small. My only issue is that they put a TON of spacers on the steerer tube and the stem has a crazy steep angle on it. Still in the process of dialing in the fit but that is the only part that doesn't seem quite right. I would have thought I would be a 56 but they said because of the higher BB yadda yadda....

    The last few bikes I've have all been used frames that I've built up myself so I didn't really have to much of a sense of "proper" fit so I kind of just rolled with what they recommended.
