Continental 0100257 CycloCross Speed Reflex 700 x 42 Urban Tire follows the elite pedigree of the Cyclocross Speed tubular. Mirroring the super-fast center-section and durably fast and comfortable 35mm casing of its tubular brethren, this clincher benefits from slightly more aggressive shoulder lugs that handle hard cornering like none other. Consider the 42mm version for those easy days on the county roads or the jungle of the city and occasional short-cut through the dirt. Specs: Weight - 490 grams; Recommended PSI - 50; Maximum PSI - 85; PU - 5.
