Heres what Tama say:

TAMAs Dyna-Sync pedal defines a new power-speed-feel balance in a direct drive pedal and shatters direct drive pedal assumptions. We are thrilled to offer drummers of all styles and abilities the opportunity to utilize the wide range of pedal adjustments to discover a differentiated direct drive feel.

Key features

Optimised Transmission Design

By precisely positioning and aligning the contact point transmission angles between the cam, direct link and footboard, we achieved the perfect overall balance of power/speed/feel.

• Hinge Guard Block
• Para-Clamp II Pro
• Speedo-Ring
• Hardshell Carrying Case included

Dual Linkage

To convert rotational motion force from footboard to cam, we developed a sturdy double-link cam connection system that holds the rotation axis bearings equally from both sides.

• Footboard Angle Adjustment
• Dyna-Beater
• Sync-Coil
• Swivel Spring Tight
• Oiles Bearing

Slidable Cam

The upper cam section slides back and forth in a non-step action to adjust the cam-turning radius. The smaller turning radius results in a more dynamic (nonlinear) motion. A larger turning radius provides for a more linear motion between footboard and beater.
