- • Not ideal for: Bikes with non-standard handlebar or fork diameters outside 31.8 mm and 28.6 mm
Short stem clamps a 31.8 mm handlebar to a 28.6 mm (1-1/8") fork. High-strength aluminium alloy and a rust-resistant sprayed finish deliver a lightweight, durable upgrade.
Stable Steering and No Flex – thanks to high-strength aluminium alloy
Rigid aluminium alloy construction, combined with a secure clamping interface for a 31.8 mm handlebar and 28.6 mm fork, resists bending and movement under load. Screws tighten the clamp to hold the handlebar firmly in place without slippage.
Reliable steering feel during aggressive cornering and climbs, with less movement than many generic stems. Secure clamping keeps the handlebar position consistent ride after ride.
Lightweight Durability – with surface spray paint for corrosion resistance
Use of high-strength aluminium alloy keeps mass low while maintaining stiffness, and a sprayed surface finish adds protection against rust and heat. The combination preserves structural integrity in wet or variable conditions.
Easier handling and less added weight compared with heavier stems, while the treated finish helps the stem stay looking good and performing well over time.
Quick Conversion Fit – thanks to standard diameter compatibility and simple installation
Designed for a 31.8 mm handlebar clamp and a 28.6 mm (1-1/8") fork steerer, the stem installs by aligning the handlebar, seating the fork rod, and tightening the screws to secure the clamp. The straightforward clamp system avoids specialist tools.
Suitable for DIY handlebar swaps and quick conversions between handlebars. Tightening the screws produces a secure grip, making it a practical choice for workshop adjustments.
