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(R) compound gives the tire a livelier feel and more grip in either wet or dry conditions.26 x 2.1", psi 25-50, approximate weight 530g26 x 2.3": psi 25-50, approximate weight 570g27.5 x 2.1": psi 25-50, approximate weight 590g27.5 x 2.3": psi 25-50, approximate weight 630g29 x 2.1", psi 25-50, approximate weight 600g29 x 2.3", psi 25-50, approximate weight 640gBead: FoldableButyl wrapped bead = 2Bliss ReadyCasing: 60 TPICompound: GRIPTON(R)
