Panzer Gravel Tubeless Tire Inserts - 700c Wheel Size (Sold as Pairs)

The Panzer Gravel Tubeless Tire Inserts deliver elite anti-pinch-flat protection explicitly scaled down and optimized for the high-speed, demanding constraints of modern gravel racing and rough backcountry exploring. Sold conveniently as a matching pair, these inserts serve as a crucial mechanical buffer between your lightweight tire casing and the rim hook. By providing heavy-duty rim protection against harsh impacts, they allow gravel riders to drop tire pressures to achieve maximum traction and compliance across rough corrugations, jagged flint, and deep gravel without the constant fear of snakebite flats or costly rim damage.

Utilizing a highly engineered 5-sided pentagonal, diamond-shaped profile derived from their proven mountain bike heritage, the Panzer Gravel insert is uniquely designed to "float" dynamically within the internal tire volume. This structural shape ensures that under normal running conditions, the tire carcass can flex, conform, and roll completely unrestricted at lower pressures, preserving a natural, supple ride quality and low rolling resistance. However, the moment you strike a sharp square-edge rock or a deep pothole, the core material is perfectly positioned to absorb the force, preventing the tire from collapsing completely against the rim wall.

To withstand the higher compression forces inherent to narrower, lower-volume gravel tires, Panzer utilizes a specialized high-density, closed-cell foam that is slightly firmer than their standard mountain bike versions. After iterating through seven generations of gravel-specific prototypes to perfect the material blend, shape, and width, e*thirteen and Panzer engineered an insert that features a smooth, low-friction finish. This advanced surface treatment ensures that your liquid tubeless sealant moves around freely inside the casing to coat potential punctures, rather than being absorbed or collecting on the insert itself. A major tactical benefit of this high-density layout is its exceptional **run-flat capability**, allowing you to safely ride out on a completely flat or slashed tire to reach a checkpoint or finish line when a casing cut is too large to seal with regular plugs.

Explicitly tailored for 700c wheel setups, these inserts are perfectly proportioned to match high-volume gravel tires ranging from 38mm to 45mm in width. This puts Panzer in an elite handful of gravel-specific mousse systems capable of delivering pro-level rim and flat protection without creating frustrating tire mounting battles in the home workshop. Keep your speeds high, lock in extra cornering grip on loose surfaces, and secure a bulletproof insurance policy against unsealable trail damage with Panzer's smart, race-refined gravel engineering.

Note: Like all high-performance rim protection systems, the Panzer Gravel insert restricts standard vertical air movement. To ensure smooth, unhindered tire inflation and deflation, this system requires the use of side-drilled, insert-compatible tubeless valves.

Key Features

• Gravel-Specific High-Density Foam: Uses a firmer, denser closed-cell foam matrix than MTB variants to absorb higher-impact forces on low-volume tires


• Pentagonal Floating Design: Unique 5-sided diamond shape floats inside the tire, ensuring unrestricted casing flex and compliance at low pressures


• Sold as a Complete Pair: Comes packaged as a set of two inserts to provide full front and rear wheel protection right out of the box


• Proven Run-Flat Capability: High structural integrity allows you to safely ride out on a completely deflated or torn tire without destroying your rim


• Sealant-Friendly Smooth Finish: Non-porous closed-cell material layout will not absorb or collect liquid sealant, keeping your fluid active inside the tire


• Optimized Tire Fitment Range: Meticulously sized to fit 700c gravel configurations running modern high-volume 38mm to 45mm tires
