### ⭐⭐⭐ 







  
  
    Not sure if the center screw's threaded right for my bike
  

*by D***E on Reviewed in the United States on September 1, 2021*

I bought this to raise the height on the handlebars for my e-bike.The bad: the center screw gives a ton of resistance and keeps wobbling when I try to screw it in.  I don't think it's threaded correctly for my bike.  Also, some of the spacers still wiggle and make noise even when the screw's tightened down.The good: it seems sturdy enough for a no-stunts, no-rocks, road bike.  My riding position is much more comfortable now that my handlebars are higher up.

I thought it was not safe to use; I returned it the next day.
