stiu ca e o intrebare cam idioata dar nu stiu ce inseamna 3pc,am vazut in multe anunturi si as dori sa aflu ce inseamna ,multumesc

Se refera la un anumit tip de angrenaj , specific BMX...o abreviere de la three piece crank asta insemnand doua brate pedaliere si axul aferent.

mersi mult :)

1pc-ul e low budget, dar mi se pare o prostie. e foarte usor, dar se indoaie foarte repede. am un prieten care a indoit vreo 3 pana acum.

am si eu o intrebare,de ce angrenajul 2pc este mai bun ca cel 3pc?

pentru ca unul din bratele angrenajului este fix iar celalalt este detasabil. fiind compus din 2 piese este mai rezistent si mai usor deoarece in partea cu bratul fix nu mai este folosit surubul de fixare si nici surubul de strangere

Probabil s-a gandit ca multe modele high-end sunt 2pc ,dar cu siguranta exista modele 3pc mai rezistente decat 2pc.
