Stans No Tubes ZTR Grail S1 700c Cyclocross Wheel - Front

Bring a new level of control and security to your gravel and road rides with the Grail S1 wheel. The same patented BST-R tubeless rim design found in our original Grail rim is now available at a more affordable price. Compatible with tubeless road tires, low-pressure tubeless converted tires, and conventional tires and tubes, the Grail S1 rim offers total versatility. The Grail S1 wheel combines durable 6061 aluminum rim construction with our stronger, smoother rolling Neo hub with Durasync triple-bearing freehub. With the security of the best tubeless system in the business and a wider overall internal rim width for improved stability and control, the Grail S1 gives your road or gravel bike an edge on every ride.
