Started around dusk for an easy ride that first took me through Vaalbeek towards the Zoete Waters. When I started to cross the Waversebaan I heard a loud crack and my chain derailed. I shifted on the big ring and noticed that something had happened to my middle ring. In teh dark I couldn't exactly see what happened but it wouldn't hold the chain. So I had to complete the rest of the ride on my big ring. I rode on through Sint Joris Weert up to Wolfshagen and then left into Sint Agatha Rode. Each hill was a challenge and I had to get out of the saddle frequently to keep the bike going. I heard strange noises coming from my chainset so a bit further I stopped to check the damage. To my horror a part of my middle ring was missing. I rode on towards Sint Joris Weert again and decided to ride towards Nethen and return over Hamme Mille. When I got home I could see the damage . What I think happened? I had noticed my middle ring seemed to have a dent in it. There are 2 bolts missing so I figure I either sheared them off - not much chance, I am not that strong - or they worked themselves loose, causing the middle ring to move from left to right, making it vulnerable. The bolts must have fallen out, and with only 2 bolts remaining that would explain why the middle ring cracked on the opposite side.. I have to admit I never checked them since the rings where mounted 2 or 3 years ago. Anyways, now I need a new middle ring and new bolts. Upon checking the others they also were far from fast. Here are a couple of pictures.
