We took the tread design of the Fast Trak by adding our GRID casing. We improved an already proven tread by having more consistent shoulder blocks for better cornering traction, while the block spacing is configured for rapid self-cleaning. Meanwhile, the GRID casing provides 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 29 x 2.3"; psi 25-50; approximate weight 720g 650b x 2.3"; psi 25-50; approximate weight 670g 650b x 2.8"; psi 15-30; approximate weight 900g
