The bike has a 25.4mm diameter handlebar which is unusual for a mountain bike. πŸ˜• Fitted the new stem which was considerably shorter than the current one and it's made a drastic difference. πŸ˜ŠπŸ‘ The new stem has an excellent build quality. So far seems to be pretty robust. Good value product. Would happily recommend. Hope you found this review and the photos helpful. ## Features - Size: Compatible with handlebars of 25.4mm or 31.8mm (choose your size) and a 28.6mm (1-1/8") steerer tube, ensures a secure fit for most bikes - Strong: Made from high-strength aluminium alloy, this stem offers durability and fatigue resistance without adding unnecessary weight, giving you better control while riding - Improved Stability: Reduces handlebar tilt for smoother steering and enhances bike handling, making rides more stable and responsive - Quick Installation: Features a 4-bolt bar clamp for a solid, wobble-free hold, preventing slippage even on rough terrain - Versatile for Multiple Bike Types: The handlebar stem riser is suitable for road bikes, mountain bikes (MTB), BMX, downhill (DH), and more ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0F4CQS62J | | Best Sellers Rank | 18,724 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 19 in Cycling Stems | | Bike Type | Mountain Bike, Road Bike | | Brand | TRIWONDER | | Brand Name | TRIWONDER | | Colour | 01 Black - 25.4 x 45mm | | Country Of Origin | China | | Customer Reviews | 4.2 out of 5 stars 1,614 Reviews | | Item Dimensions L x W | 45L x 25W millimetres | | Manufacturer | TRIWONDER | | Manufacturer Part Number | OS0944 | | Material | Aluminium | | Material Type | Aluminium | | Model Number | OS0944 | | Number of Items | 1 | | Number of Packs | 1 | | Product dimensions | 45L x 25W millimetres | ## Product Details - **Colour:** 01 Black - 25.4 x 45mm - **Brand:** TRIWONDER - **Material:** Aluminium - **Product dimensions:** 45L x 25W millimetres - **Manufacturer:** TRIWONDER ## Images ![TRIWONDER Bike Stem 25.4 31.8mm Short Bicycle Handlebar Stem 38 45mm Aluminum Alloy for Mountain Road Bike MTB BMX - Image 1](https://m.media-amazon.com/images/I/61rFKHfCC-L.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great item *by R***B on 17 March 2026* Great item very light works well although needed a shim to the bars but looks great ### ⭐⭐⭐⭐⭐ Excellent quality, decent value *by J***R on 1 May 2021* Bought a mountain bike for the Mrs (Rockrider ST120 from Decathlon) but the stem was too long for her to reach comfortably.
