Any question when you receive the item or in using, please feel free to contact us, we are always here to help you.

Q: Is the break lever made of any sort of metal?
A: It's a solid piece of aluminum. It seems very sturdy. The shifters are also metal but they have a plastic end.

Q: What rear derailleur would work best with this set?
A: You could go with a Shimano indexed 7-speed derailleur like Acera or Alivio. You could also go with a Tourney, if just planning on some city riding.

Q: Is it hard to change shifter cable on this?
A: Not at all. You just move the shifter to the lowest position, retire the cover of the shifter by unscrewing the three screws, pull out the damaged/used cable and insert a new one.
