KRSEC R009 MTB Short Stem Aluminum Alloy Performance Specs
The high-strength aluminum alloy body resists impact and vibration while maintaining featherweight characteristics that don’t compromise your bike’s overall balance. CNC precision engineering holds tolerances to 0.15mm across all contact surfaces, ensuring zero play between stem and fork steerer or handlebar. Its short stem profile reduces rotational mass and quickens your steering input, crucial when navigating rocky descents or tight switchbacks on trail. The 31.8×28.6mm interface fits the vast majority of modern mountain and road bikes without requiring adapter sleeves. Anodized finish protects against corrosion while maintaining a clean aesthetic that complements any frame color or build style.

What a difference in agility on tight windy trails compared to the old 90mm stem. although its different in shape and style from a normal one so the garmin mount is more upright now.

It wasn’t the color I expected, so I give it 4 ⭐ but it still looked excellent on my bike. Those letters on the sides give it a nice style and good material.
