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. ## Features - Perfect for Most Bikes: The stem riser is suitable for most bike with 1-1/8'' (28.6 mm) threadless steerer. Your bike can do more with this mountain bike stem extender, checking video to install your bike - Adjustable Height: The bicycle stem riser offers up to 85 mm stem height increase, you can customize your new riser stem height perfectly for your riding needs - 4 Spacers Included: The stem riser adapter comes with 4 spacers (1×5 mm & 3×10 mm), so you can adjust the height of the riser stem by swapping spacers - Easy to Install: Just slide the stem extender onto the steerer tube and tighten it. This bike stem extender is very easy to fit - Aluminium Material: The steerer tube extender is made from forged 6061 aluminium alloy, super strong and lightweight.

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 ### ⭐⭐⭐⭐⭐ Best performance upgrade - a bargain at 3x the price *by J***B on January 9, 2026* I couldn’t find a bar with both rise and bend that were perfect.

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. ## Frequently Bought Together - LERWAY Bike Stem Riser Extender MTB Handlebar Stem Adapter with Hex Key for 1-1/8" 28.6mm fork Aluminum Black - GoHZQ 6 Pcs Headset Spacers 1 1/8", Aluminium Alloy Headset Spacers for Bikes, 28.6mm MTB Road Bike Stem Spacers 2mm/3mm/5mm/3x10mm Black - PLATTBK Bike Stem 31.8mm 35Degree, Aluminum Alloy MTB Stem Riser Bicycle Handlebar Stem for BMX Road Bike Mountain Bike --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/763213-lerway-bike-stem-riser-extender-mtb-handlebar-stem-adapter-hex](https://www.desertcart.at/products/763213-lerway-bike-stem-riser-extender-mtb-handlebar-stem-adapter-hex) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-14*
