I have mounted a new set of carbon rims on my bike. To be precise, it's a pair of Mavic Cosmic SL. And I've noticed that they have some little "holes" along the profile.
What are they used for? Since I'm planning to attach the stickers on them, I like to know if I can cover these holes with them, or I have to adjust the stickers in a way to let these holes free.
Sorry if it is a silly question, and thanks for any help.
