hi guys is me again, after the big fail of conversion to a 3 speed, (chain skipping all the time dont know why...is not falling on the side because the chain is straight in line with the derailleur..anyway)
i was thinking to change the rear cog and hub (wich is a freewheel

My question is, if im going to convert from a freewheel system to a cassette , do i need to change my rear derailleur as well or i can use my current one (wich is working with the freewheel?) ??
