Just remember to use a torque wrench so you don't exceed 5 nm and risk damaging it. ### ⭐⭐⭐⭐⭐ Colour *by on Reviewed in the United Kingdom 2 September 2026* The blue is a bit lighter than on the picture but it’s a good solid product and hasn’t failed on my yet ### ⭐⭐⭐⭐ Decent stem but no installation instructions for torque settings *by on Reviewed in the United Kingdom 29 April 2026* Doesn't come with any indication of required torque setting so just applied some common sense. Not being used for jumping/downhill so shouldn't be an issue. ## Frequently Bought Together - JUPSK 31.8mm Bike Stem, Cycling Bike Stem Short Handlebar Stem Lightweight MTB Stem for Most Bicycle Road Bike BMX MTB - NUWAB Premium Bike Handlebar Grips, Professional Mountain Bicycle Grips with Soft Anti-Slip Rubber, Single Lock-on Bike Handlebar, 2PCS Allen Wrench Come With - Wake Bike Handlebar Aluminum Alloy Handlebar Riser Bar Wide Extra Long Bicycle Handlebars for Downhill Cycling Racing for Road MTB Mountain Bike 31.8MM * 780MM(Black) --- ## 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.tn/products/344320964-31-8mm-bike-stem-cycling-bike-stem-short-handlebar-stem](https://www.desertcart.tn/products/344320964-31-8mm-bike-stem-cycling-bike-stem-short-handlebar-stem) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-26*
