As others have stated, this stem is very very well made and I particularly liked the fact that the adjustment sat on the top of the tube instead of out front. The adjustment actually has teeth that mesh together when tightened, which make this much better than a friction based system. The way this feels when tightened, I cannot imagine this ever slipping. Now a cautionary word or two about installing this on a carbon fork steerer tube. This comes with a star compression nut assembly which is installed into the fork tube to tighten the main stem body to the tube. This is fine for alloy or steel fork tubes, but should not be used for carbon fork tubes. On carbon steerer fork tubes, an expansion / compression nut should be used. Since my fork is carbon, the original stem assembly on my bike did have an expansion nut, but I discovered this was too short to be used with this adjustable stem. I had to purchase a 50mm long expansion nut assembly separately to install this new stem on my bike. Below is the link to the one I found on Amazon, which cost around $10. I used this one without the black top cap and it worked perfectly. I feel the company selling this excellent product would benefit by having two styles available. One sold with the star compression nut for alloy and steel fork tubes and another sold with a compression nut for carbon fork tubes. It also would be nice if they included a picture of the internal parts in the listing. Other than this, I highly recommend this stem and would definitely buy it again should I need another one.https://www.amazon.com/gp/product/B077JMWY8X/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1 ### ⭐⭐⭐⭐⭐ Works well on Trek 820 mountain bike. *by C***A on Reviewed in the United States on November 27, 2019* I felt I had to lean too far forward on my new Trek 820 and wanted to sit more upright. I debated between this and replacing the handlebar with more rise and/or the stem. Looking at the photos and reading the reviews, this adjustable stem seemed to be sturdy and functional. If this alone didn't give me the height I was looking for I was going to replace the handle bar next. Luckily, two clicks forward from the vertical position gave me the perfect seating comfort. All the parts are of good quality, and I expect it to be trouble free for many years.I added some thread locker to some of the bolts just as a caution. I kept 3 spacers below this stem, and the steer tube doesn't quite clear the top clamp as much as I would like. Once installed, everything felt rock solid with no looseness or noises. Recommended. ### ⭐⭐⭐⭐⭐ Easy in install and adjust. *by D***A on Reviewed in the United States on October 2, 2018* On of the best threadless adjustable stems. Most have the adjustment offset from the steerer tube which even fully adjusted can keep the bar low for comfort purposes. This moves the pivot to above the steerer tube much like a threaded version does, this means you get the full benefit of the pivot. There is also plenty of space above the pinch bolts to allow for plenty of height adjustment as well, just remember that the top of the steerer tube needs to sit level with the top of the upper pinch bolt. In the case of the install in the picture I included I did this which also moved the handlebars up, another 2 spacers could have been removed if I wanted the bar lower without moving it forward via the pivot. No top cap needed and the adjustment is just one 6mm wrench. Simple, easy and well thought out. --- ## 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.co.th/products/21722135-31-8-x-85-mm-alloy-40-140-degree-adjustable](https://www.desertcart.co.th/products/21722135-31-8-x-85-mm-alloy-40-140-degree-adjustable) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-26*
