## Description

desertcart.com : Azarxis Aluminium Alloy Handlebar Riser 123 mm Extension Stem MTB Fork Stem Extend Riser for 1-1/8 Inch 28.6 mm BMX Road Bike (Pure Black, 12.30) : Sports & Outdoors

Review: Very tall rider - I had previously added a stem extension but needed more. The 185 mm is over six inches of rise. It worked great. Screw was plenty long. Cables got a bit tight but the included spacers allowed me to get max height without modifying cables. Well built. Rides are more comfortable. Very happy.
Review: Best $10 you will ever spend on a bike - I got this because my Trek FX 3 had its handlebars with a pathetically short max level for the handlebars and i was too tall (6 feet) to work with it easily. The curve gave me back pain and the strain made my arms and wrists hurt. This extension for the stem is kinda short itself, but it's the perfect height for the FX3 and doesn't require significant retooling of it's brake lines to work properly. Tools needed are just Hex wrenches. Remove the top hex bolt and loosen off the two side ones. Job can only be hard if you accidentally overtighten something, so this is very DIY friendly (if you do overtighten a set of hex pieces and an impact wrench/power drill can bail you out). I might have preferred more height on my bike, but with this extension I'm feeling some SERIOUS relief and thats amazing for less than 10 bucks. I have not put this piece through full field testing, but it appears to be made solid/sturdy aluminum and I trust it for my rides. Don't live with pain and discomfort if your ride doesn't work with your height. Buy one of these and look forward to a fun ride!

### ⭐⭐⭐⭐⭐ Does the job
*by R***K on July 25, 2025*

Worked perfectly on my bike, good quality. Comes with an assortment of spacers that was useful in positioning the bars. The more upright riding position relieved some stress on my hands and wrists. Glad I bought it.
