Curious to see the worst parts anyone has ever ridden. Not by brand or anything, but due to premature failure or poor build/material quality.
I’ll go first.
Reed stark BSD pedals - feel very flimsy and damage easily.
Shadow little ones PVC peg sleeve - cracked and wore out really quickly
FBM PMA Frontload - bolt hole stripped out, although this is likely due to previous owner fucking it up
Cult vans grips - do I really need to say anything?
Fiction grips - absolute hard rubber garbage
Any Barend that isn’t hard plastic or metal
Stolenbikeco cranks - 19mm 48 spline, have this weird ass issue where the sprocket bolt hole sits slightly lower than the spindle hole so the sprocket sits unevenly when bolted down
About all I can think of off the top of my head - let’s hear yours!
