Thanks guys, you're making it easier
.
No, really: if both are in fact pretty equivalent, I can go with the one I think looks the best
. However that may be a problem since both look VERY sexy to my eyes...
And what about the 28C tires? Could anyone please confirm if I can easily use a 28C on both? I haven't got in touch with the SPZ rep yet, but the Cannondale guy said
"Yeah, they fit" when I asked. But I would like a more down to earth reference on that since in my past experience something branded as yeah-they-fit may only translate to it will fit in there if you hammer it in with a mallet.
They aren't equivalent.
They don't have the same geometry
They don't have equivalent ride quality
They don't handle the same.
They don't use the same bottom bracket. You can actually get a '16 Roubaix...not all model Roubaixs...with an English threaded BB...a very good thing.
They don't use the same seat post. A big deal if you want the best seat post. Synapse has proprietary 25.4mm dia post which severely limits seat post options.
