I used to break stuff all the time when I was new to it, but then stuff wasn’t so tough back then and I was riding cheaper bikes than now.
I’m slowly replacing the spokes on my back wheel as they snap 1 or 2 at a time every few weeks, given the current rate that my LBS charges to replace a spoke and retrue a wheel it’s going to cost me £432 to replace all the spokes over the next 18 months.
I destroyed 4 fancy and bloody expensive X9 derailleurs in 3 days in the Alps once before I noticed the bike shop had fitted another punters chain after the first one broke so every time I went full travel the chain would snap them.
Cracked a chainstay on my Enduro, blew up a DHX air shock, cracked the lowers on a set of 36s – same bike, common faults.
Destroyed approximately 734 ISIS BBs – a good fortnights worth, they were terrible.
