As in the most problematic, crappy feeling or low quality part that you have ACTUALLY RIDDEN
for me it was my primo v2 strands, way too snappy and made it really hard to go very fast (i had a 75 headtube)
or my v1 pleg, thing was too flexy. should have kept the insert, ive been pegless for a couple days and a micropeg would be pretty cool
