>>1652251>noticeable shift in the quality of materials used in componentsShimano lead the way in this, mostly they got it right where weaker materials could be used, but there are some common failure points
>Rear Derailleurthe Bushing for the B axle is thin and wears out quickly
the P Tension spring is weak and looses tension over time
>cheep Front Derailleurthe link plate is partly made of delrin, altho not strictly load bearing it does locate and aline the metal portion of the link plate
>oversized aluminummostly I have seen the chain stays break off
very rarely a down tube will get cracked
