Kremorv Bike Stem Riser Extender - 31.8mm Aluminum Alloy Bicycle Fork Stem Adapter for MTB, Mountain, Road & BMX Bikes - Perfect for Comfort Adjustment and Handlebar Height Customization

I'm a tall guy and this works well to raise my handlebars a bit.I took a chance on this despite not knowing whether it would fit or not. It fit perfectly and the center bolt was the correct size and thread. I needed extra height on the bars to keep the weight and pressure off my hands and wrists and this does the trick. The price is very affordable.Muy lindoThis was so easy to install and made a huge difference on my ride comfort. I did have assistance in stabilizing the bike and front wheel but other than that just used my bike tools and was finished in less than 10 minutes.Goal accomplished- I can now ride in a more upright position taking stress off my wrists!Install was straightforward after I found guidance on-line (instructions not included).If another spacer set had been included, I would have set the handlebars even higher (note the adapter stem protrudes above the bar mount about an inch in the photo). Can spacer rings be obtained separately?Very easy to install. Purchased two. One for my wife's Aventon and one for a ecotric mountain bike. Both were 115mm riser.I bought this for a new Huffy bike. First off, the cap screws are too short and immediately stripped when trying to tighten them. I bought longer screws but the device, as designed, won't allow it to be tightened around the riser from the forks enough to feel secure, and to be assured that it won't loosen when riding anyway. I'm chalking it up to a lesson learned, and will buy a set of handlebars with the rise that I want instead. You live and learn...Stem riser was easy to install and it works perfectly.Lifts the riding position to make the cycling more comfortable.
