Cause of Oblique Pain When my wife gets done with a long ride she finds that her right oblique hurts, while her left does not.  Does anyone know a possible cause of this, like improper form or saddle fit?
Could be a number of things:


Saddle/cleat/handle bar misalignment
bad form on her right side, not spinning circles, etc


Have you ridden with her and checked out her form? Is she favoring one side over the other?
