Review: Comfort and Quality at a great price - Put this on my Trek X-caliber 9 mountain bike, been riding a lot on dirt roads and rail pathways this spring so i have been riding in the saddle most of the time (not really what the bike is designed for), as a result my neck and lower back have been aching after the ride, so i figured i would give this inexpensive stem a try. The stem looks very well made and finished perfectly, no complaints here. Swapped out the stock bontrager stem (80mm long / 7 deg) and after 2 rides i am feeling much better, neck strain gone and lower back ache improved. It just puts the bars in a much better position for me, i might go back to the stock bontrager stem when i start doing single track but for now i am loving this stem and would recommend to anyone looking for a little more comfort on their cross country ride. ## Features - !!!

I am 6'1 with a 31 inch inseam and on my XL Trek X Caliber 8 bike, the reach was a bit much putting way too much weight on my wrists and made for a uncomfortable ride. Asked Chat GPT how to fix it, and it recommended replacement of the stem. Found this, looked about what I needed, shorter and taller, put it on and WOW! Now I am more upright and comfortable and feel that the XL frame is PERFECT! If you end up buying a bike that may be a tad big, give this thing a shot, made a WORLD of difference. Install is very easy with basic hand tools. --- ## 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.be/products/63904026-35-degree-stem-31-8-x-70mm](https://www.desertcart.be/products/63904026-35-degree-stem-31-8-x-70mm) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-29*
