We took the tread design of the Fast Trak 2Bliss Ready tire a step further by manipulating each knob with FE Analysis. We improved an already proven tread by having more consistent shoulder blocks for better cornering traction, while the block spacing is configured for better self-cleaning. The tread of this 2Bliss Ready version is also slightly wider compared to the S-Works version, which protects the sidewalls and delivers additional cornering bite. Lastly, our proprietary GRIPTON compound gives the tire a livelier feel and more grip in either wet or dry conditions. - Casing: 60 TPI - Bead: Foldable - Butyl wrapped bead, 2Bliss Ready - Compound: GRIPTON - 29 x 2.1", PSI: 25-50, approximate weight 600g - 29 x 2.3", PSI: 25-50, approximate weight 640g
