Zipp's Tangente Course G40 (700x40c) is a purpose-built tubeless gravel/off pavement tire for smooth control over untamed roads. Grippy for aggressive riding, this tire provides the control and durability demanded by gravel, dirt, rocks, mud, whatever.
The Tangente Course G40 is a wide (40mm) tire designed for control, which in gravel translates into higher overall speed. In developing this tire, Zipp began with a chevron center-tread pattern for speed which transitions to an inverted soccer cleat design and added XC-style knobs on the edges for the ability to dig in when you need it. Durability was crucial.
The tire's casing and bead-to-bead puncture protection strip navigates the fine line between supple and stiff so that grip and performance do not suffer while making an incredibly durable gravel tire. The tire's 40mm width was carefully selected to be most effective with its tread pattern while also fulfilling riders; evolving preferences for wider tires for gravel events and off-pavement riding. It's just what you need for gnarly all day riding. It performs exceptionally well with Zipp's widest and most versatile rim, the 303.

Looks Great, Performs Adequately
This is a great tire if you are looking for something to ride on tackier packed gravel roads rather than dusty and loose. These tires feel great on hardpack, but less stable on loose gravel where a more widely spaced tread pattern will excel. As it is, those side knobs don't really engage when you need them too, and I have mostly felt unconfident pushing these tires on looser gravel like is the majority where I live.
