Sheesh...I've never seen a Thomson break.
That front cap thing is worrying but on the other hand I do think that just about every bike bit has been broken by someone either through being a numpty or crashing. There were a load of people who managed to crack their Easton Havoc stems. Not sure how because they look properly burly.
Race Face stuff has alwasy been good for me...even their bottom brackets that everyone else seems to destroy. My Deus headset on the SX is still OK despite not being used for Cross Country.
