How to tell if rims are worn?
As the title says really. I've been riding some pro-lite braccianos for 3 years or so and have done maybe 6k on them. The rims don't have a wear indicator but having just had a look and a feel there is a definite concave profile of perhaps a millimeter to the braking track. I haven't noticed any issues other than that with them. I live in the mountains and do lots of hurtling down them as well as slogging up them and I weigh 79kgs using swisstop pads if that helps. Should I be worried, replacing?
