Where speed and trail tough cut-resistance intersect, you'll find our Fast Trak CONTROL 2Bliss Ready tire. It takes the legendary tread design of the Fast Trak a step further by manipulating each knob with Finite Element Analysis—creating more consistent shoulder blocks for better cornering traction, while also optimizing block spacing 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. Our new CONTROL casing has a slight extension in the casing overlap to give the best prevention of pinch flats.Lastly, our proprietary GRIPTON® compound gives the tire a livelier feel and more grip in either wet or dry conditions.Casing: 60 TPIBead: FoldableButyl wrapped bead = 2Bliss ReadyCompound: GRIPTON®26 x 2.1", psi 25-50, approximate weight 530g26 x 2.3": psi 25-50, approximate weight 570g29 x 2.1", psi 25-50, approximate weight 610g29 x 2.3", psi 25-50, approximate weight 650g
