Spank Spike Vibrocore Bar

Vibrocore is a proprietary foam core injected inside the handlebar. It is designed to absorb high-frequency vibrations and trail chatter before they reach your hands, which helps reduce arm pump and fatigue during long, aggressive rides.

Yes, the Spank Spike Vibrocore bar is rated for ASTM 5 usage, which includes e-bike applications. It is built with extra durability to handle the increased weight and forces associated with electric mountain bikes.

This handlebar features a 31.8mm clamp diameter. As long as your current stem is designed for a 31.8mm bar, it will be compatible.

No, this handlebar is not Di2 compatible. It does not feature the necessary internal routing ports required for Shimano Di2 wiring.

While it can be used on any mountain bike, it is specifically engineered for trail, enduro, and freeride disciplines. It prioritizes vibration damping and durability over the ultra-lightweight construction typically preferred for cross-country racing.

The chamfered clamp area is designed to reduce stress risers, which are points where fatigue and cracking often start. This design helps extend the overall fatigue life of the handlebar, making it more reliable over time.
