I recently built my first wheel with an Araya PX-45 rim that I bought used and a Shimano hub. However, once I got the wheel built I realized the braking surface was concave. In researching this on the net I found that Araya built some rims intentionally with concave braking surfaces. Does anyone know if this particular rim was built this way or is it just worn out and should be replaced?
Thanks so much in advance......Bumbliwa
Oh, and by the way it's a 700c wheel....
