Do look to be somewhat of the same notion, especially similar TT/DT specs. Beefier ST and stays on the SP set. So the latter, all told, is a little 'stouter', I guess.
I have no experience (or knowledge beyond the posted links) of the Oria RANF tubeset, but this topic is of interest - as a tall, heavy rider, I do like my one SP bike for its stiffness, and will be keeping an eye on this thread for others' impression of the Oria set.
