My bike is at the shop again and I getting repaired. The rim of the rear wheel cracked, obviously from braking. I was quite astonished to see the crack because the rim is a 26” Mavic Extreme (EX 721), one year old and had only 4000 km on it’s back. The third Mavic rim in a row, nearly one per year. The “old” Mavic ceramic rim on my front wheel is already doing its service for nearly ten years. It’s a shame it’s hard to get ceramic rim or other durable rims today.

I now decided to get a complete cheap wheel with a Rigida Explorer rim and a Shimano Deore hub for city and light cycling. And I told my bike shop to get quotes for a new ceramic rim or similar durable rims from DT Swiss.
