Ritchey WCS Shield 29x2.1 Tubeless Ready Tire
The Ritchey WCS Shield tire's low-profile tread and near continuous center knobs make for a fast rolling, race-ready tire. The Shield's confidence inspiring corning traction comes from the specific shape and placement of knobs developed using Ritchey's VFA (vector force analysis) process. Its low rolling resistance and superior traction create a great all around XC/Trail tire.
This is without-a-doubt the best tire for Socal's loose and dry conditions that I have ever ridden. Extremely light, yet I've had absolutely no issues as far as flats go (I run them tubeless). I use these as my race tires and every time I switch them back on my bike they absolutely blow me away. The only downside is that they tend to wear relatively quickly, but that is to be expected with this type of tire. Forget RaRa's, RoRo's, and Race Kings. This tire trumps them all.
