Specialized took the tread design of the Fast Trak GRID tire a step further by manipulating each knob with FE Analysis. They improved an already proven tread by having more consistent shoulder blocks for better cornering traction and block spacing is configured for better self-cleaning. GRIPTON compound gives a livelier feel and grip is enhanced in wet or dry conditions. They recommend GRID tires for anyone seeking the utmost in flat and sidewall protection.
- Casing: Additional sidewall protection for exceptional durability, plus added sidewall stiffness for enhanced stability.
- Bead: Foldable
- Butyl wrapped bead = 2Bliss Ready
- Compound: 60a
- 29 x 2.1" psi 25-50; approximate weight 670g

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 bead. UST rims should be paired with UST-specific tires for best results.
