A very beginner's question: the twist shifter wheel only spins forward, how do i shift it back? it does not seem to spin backward. thanks!
twist it the other direction
I like cheap stuff that works great and is very sturdy.
and i know it's not the bike's problem as it's pretty new.
either you're not using enough force to twist it back, or its broken.
if you're semi-constructive you can probably take it apart and find the broken/dislodged part and fix it...or find out what needs to be fixed. if not, buy a new one.
