Review: Works great - Made it easy to fix our grandson’s bike
Review: Exact Replacement for Many Bicycles - Picked up a free bicycle with one of these derailleurs and what I got was an exact replacement. After pulling the gears to get the chain on, I simply had to screw the unit into position. Then I hooked up the cable and setting the bike up, I was able to go through the gears and make adjustment to the cable and fine tune it with the adjustment screws. Works perfectly. Also had to buy a seat post and seat pad and now I have a new bicycle. My old one was too small for me but my 12 year grandson loves it.

## Questions & Answers

**Q: Does this unit have the "B" screw ?**
A: this is exact replacement and I do not see a "B" screw works fine for me

**Q: Is this short cage**
A: yes，the  rear derailleur RD-TZ31-A is  short cage,and it compatible with 6/7 speed mountain bike.

**Q: Is this a real shimano part ? The shimano version is steel and resin ,not alloy .**
A: This is copy cat

**Q: Does it come with the little metal wire thing? That goes to change the gears**
A: You are probably talking about the shift cable/wire. If that is the case the answer is no it does not come with the derailleur. I would order derailleur wire/cable when you order the derailleur or better yet contact the vendor that you are dealing with and ask them to sell you a shifter wire to send with the derailleur.
