New. Grippy and light at 665g. This is a great deal at $50 each and I have three of them. The new Booster is a World Cup proven XC race tire that is aggressive enough to push traction to new limits. On top of that, it is also one of the fastest and lightest XC tires on the market. You no longer want to choose between a XC tire that is either fast and light, or provides great traction? The all new Booster combines the best of both worlds.

• New tread design - Modern and aggressive look, optimized for fast rolling and best in class cornering traction.
• New race compound - The Booster utilizes a newly developed race compound that is fast and grippy, especially on dry, loose over hard and rough and rocky terrain.
• Offered in two different casings - TR and SCT (with side wall protection).
• Tubeless ready
