Silca says, \u201cthe tires [they] wanted to ride didn\u2019t exist\u201d<\/em>, so they created four Protocols of their own. Always there for the marginal gains, Silca wasn\u2019t happy with the current crop of large-volume race tires available. So they laid out a development brief (or protocol<\/em>) of what they really wanted from a modern dropbar race tire. From 29-38mm road tires. And from 45-55mm gravel tires, plus an even bigger 32\u2033 x 2.4\u2033 gravel tire for good measure (which we spotted on that Leadville prototype Ventum<\/a> last week.<\/em>) <\/p>\n

Either scaled up from skinny road tires of the past, or scaled down from XC mountain bike tires, Silca felt like existing wide road and gravel race tires were lacking in performance, specifically tuned for how we race bikes now. So instead, Silca<\/a> combined lessons learned from road & off-road tires, but rebuilt them from the ground up with lighter, faster casings and treads optimized for efficiency and control in a wide range of riding & racing conditions.<\/p>\n
