I got some questions about rims and i am thinking to upgrade them. So i got mavic X139 rims laced with 15g spokes on my specialized hard tail. So far they are not broken , the rear is slightly out of true. I am considering getting either F219 or X317 rims (disc). I like the 317 a lot but i am wondering if it will hold me well doing aggresive XC and weighting 200lbs. So far i got no problems with the X139 which i presume is more fragile than the X317. Also i am wondering how much do X139 rims weight and also of their profile-width dimensions. I would also like to know of the profile-width dimensions of the X317 and F219 rims. I presume that with the X317 i ll get lots of acceleration.
thanks for the forthcoming answers.
