I have a 15 year old Randonee that came with Mavic MA2 rims. The rear needs replacement now
So now the question - Do I just get a new Mavic (now Open Sport) and spokes and call it a day, or do I replace both rims? The reason I ask is that if I am going to do both, I'll switch to A 319s.
I have examined the front rim, and there are none of the micro-cracks Mavic rims are known to develop, but I can feel i slight ridge near the lip, indicating that there is noticable wear on the breaking surfaces. The wheel has been fine, with only minor truing over 15 years and about 25,000 miles, but is that the point of wear out?
So - Those of you with lots of experience:
The MA2s did fine on a loaded Portland to SF trip 15 years ago, but should I really consider stouter wheels for the TransAM? That would tip me to replace both.
Or should I just replace the rear rim?
Personally, I would just replace the one rim. As to stout, MA2 rims should be fine; the build quality is more important. As you know, MA2 or its successor will limit you to 32mm width tires (actual measurement), which should be adequate, although you may think you need wider rubber. I've found the Open Sport rim easier to build, which also means it should stay true longer. I have not noticed micro cracks on my Mavic rims. Is this something more particular to anodized rims? If I was switching to A319 rims it would be because I want to install wider rubber, not because I thought MA2 rims weren't stout enough to tour.
