I recently bought a carbon 20mm wheelset for a tour des Alpes in autumn. The guy selling it described it as good as new. I usually don't need 20mm rims, because I do live in flat Berlin.
Anyway, today I had a closer look on the frontwheel.
Very light but the front wheel has some tiny holes in the braking surface. It has also some abrasion from the previous used(supposedly cork) braking pad in the holes.
For I only have very little knowledge about carbon rims as I do only have a Zip404 to compare, which doesn't shows this little holes, I'd need some advice.
Are this tiny holes are generally a problem or usual for carbon rims in general.
Any idea If/how it will effect the braking performance?
Furthermore Iam thinking about what to do with this holes. Putting resin in the holes and polish it afterwards?!
Or leave them as they are? Any additional ideas?
Thanks a lot
