Challenge Paris-Roubaix 700c 27mm Black/Tan
A fast, light, and comfortable road tire. A nice option to the Grand Bois Cerf 700x28. A very comfortable premium performance tire. Good for gravel and other poor quality roads. These will fit under a standard road caliper, or a short reach caliper that is set up for max pad extension.
When mounted on a 23mm rim, they stretch out to be a 29/30mm tire, and 28mm on an Open Pro/DT RR rim.
