Metron TFA EVO Stack Kit, Triathlon/Time Trial Aerobar Spacer Kit, Underside Bolt Assembly

Vision Metron TFA EVO Stack Kit is a triathlon/time trial aerobar spacer kit with the underside bolt assembly required to adjust and securely fasten stack height on compatible Vision Metron TFA EVO aero bar setups. It’s the right choice for riders fine-tuning pad/armrest height for comfort, fit, and sustainable TT position—or for replacing worn or missing underside hardware to keep the cockpit tight and serviceable.

• Armrest Stack Adjustment - Adds height where it matters for dialing pad position, improving comfort and helping maintain an efficient hip angle in aggressive TT/tri positions
• Underside Bolt Assembly Included - Restores proper fastening hardware for a secure, consistent interface when changing stack or replacing parts during service
• System-Matched Compatibility - Purpose-built for Vision Metron TFA EVO aerobar configurations to simplify fit changes without improvised hardware
• Service-Friendly Solution - Ideal for rebuilds, travel reassembly, or routine cockpit maintenance on triathlon/time trial bikes
