It's back! This early 90's stalwart has been updated with new materials, a new tread pattern, and a new, fast-rolling 29-inch diameter. The new version of Specialized's S-Works Ground Control 2Bliss Tire is a confident-cornering tread that excels in a variety of conditions. Specialized used finite element analysis to optimize the side knobs for grip, create a fast-rolling center section, and provide great braking control. Plus, with Specialized's 2Bliss technology, you can run these sweet tires at traction-enhancing low pressures with no risk of pinch flats.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
