Spank Flare Vibrocore Drop Bar

Vibrocore is a proprietary foam core injected into the handlebar that acts as a damper. It specifically targets high-frequency vibrations, which helps reduce hand numbness and arm fatigue on rough gravel or technical terrain.

The wide 25-degree flare pushes the drops outward, creating a much wider stance than a standard road bar. This provides significantly more leverage and stability when you are descending or navigating technical, loose surfaces.

Yes, it is designed specifically for that purpose. The combination of the vibration-dampening core and the short reach and drop geometry helps maintain a comfortable, balanced position over long hours in the saddle.

This bar requires a standard 31.8 mm clamp diameter stem. As long as your current stem uses that measurement, it will be compatible.

The round profile is a classic design choice that offers a consistent, secure grip across various hand positions. It is generally more versatile and easier to wrap with bar tape than flattened, aero-profile bars.

ASTM 3 certification indicates that this handlebar is tested and approved for rough off-road riding, including jumps up to 24 inches. It confirms the bar is built to withstand the stresses of aggressive gravel and trail use.
