## Questions & Answers

**Q: I cant get the handle bars right. Has a little play at the frame. How can I fix it.**
A: You might have to use your existing spacers and the ones that come with the new stem to get the play out. It happened to me at first until I got the spacers just right.

**Q: Can u use this on a 20inch fit bmx bike?**
A: Don’t have that bike but it fits five other makes and model bikes I have and it’s powerfully strong I’m a big guy its great

**Q: Does this work on the Peloton?**
A: Look in your Peloton  manual to see if it tells you the size of the pedal thread.

**Q: If you only use one or two spacers, can you cut the steerer tube extension to the correct height? If so, will the provided longer bolt still work?**
A: no put the spacers you don't use on top.
