Ritchey: 
The low-profile tread pattern on the Shield provides perfect all-round qualities with incredible traction and control. Side knobs employ VFA design for consistent traction at all cornering angles. The WCS version is tubeless-ready and features dual compound - softer side enhances cornering, firmer center section rolls faster and is more durable.
