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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits Giant Talon 3 bike *by on Reviewed in the United Arab Emirates 18 February 2026* Fit my Giant Talon 3 Bike (29 er) very wellThe handlebar is raised to a comfortable position now.
