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, and mud.
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 that transitions to an inverted soccer cleat design, then they 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, and it also performs exceptionally well with Zipp’s widest and most versatile rim, the 303.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.
Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.
UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
