Review: Best performance upgrade - a bargain at 3x the price - I couldn’t find a bar with both rise and bend that were perfect. So I finally got this, and once I figured out how to seat the spacers at the bottom, and filled in spacers on top, fitted the stem, and put my favorite bar on, it’s insanely perfect. It just looks like another tube on a bike once you get used to it. Seat tube, fork tubes, frame tubes, steerer tube. Brings my 5” rise bar up to about stomach height, which is perfect for off-road trail riding. Not casual, slow, easy beginner trail riding. Full on moto BMX on the woods. Learn to counterlean and get a setup that gets your upper body weight off your bars. Easy install (though the spacers can be a puzzle possibly), very sturdy, simple component, good quality, and the absolute best upgrade for performance for the buck I’ve ever gotten. (The tracker bend bar cost $30.)
Review: Easy to install, makes a MAJOR difference in comfort. - OMG Yes! Day 3 of owning a Lectric Xpress 750 High Step and installed this stem riser and it makes all of the difference. Im 5'9" with a 30" inseam and I experienced wrist pain on my 1st short rides from leaning over and having to much pressure on my arms and wrists. Raising the stem has created a more upright riding position relieving the wrist pain and pressure immediately as well as relaxing my neck position. The install really was simple and quick following any of the many YouTube vids. I am not racing or off roading but rather commuting and doing recreational rides mostly on roads. This is an amazing mod. And the high quality of these components are well engineered.

## 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.

### ⭐⭐⭐⭐⭐ Wish I had done this years ago - Lerway stem extender is great
*by T***1 on May 29, 2025*

Ever since I bought my DiamondBack Apex in 1995 (it was a high end bike in those days), the handlebars have been a little 'aggressive'. After I crashed and burned on a technical trail and separated my shoulder many years ago, I moved on to less challenging rides but the handlebars were still uncomfortable. 10 years ago I went to the local bike shop to see if there was a simple, inexpensive way to put a taller stem on the bike and they told me there wasn't. I don't know if this was liability-related, but turns out there is and the Lerway extender is it. A little different setup than most as I have only a single binder bolt (?) for the handlebars with my Tioga Alchemy headset. But the installation (very easy) is exactly as shown in the Robin's Testing Studio video found on the Amazon site. Also, other videos available on-line. I didn't use all of the adapter rings because using the full stack height was a little too much to completely insert the stem into the handlebars. I ended up using 2 1/2 rings which overall raised my bars about 3 1/4 inches - which was just about the perfect adjustment. Following the on-line instructions this is an easy install and doesn't require you to be a bike mechanic to do the job. Allen (hex) wrenches are included for the Lerway components. I did need a different allen wrench to loosen the binder bolt on my handlbars. The end result is a perfect riding position, and provides a lot of flexbility for your specific height adjustment. Looks good and was an extremely good value for the money. Sorry I didn't find this years ago.
