Tire Insert Panzer Gravel Anti-Pinch-Flat Insert sold in {PAIRS} for 700c tyres only
Using the same basic 5-sided shape as their MTB tire liners, the new Panzer Gravel scales down for 38-45mm wide gravel bike tires, making it one of just a handful of gravel options (with CushCore & Mariposa Tyreinvaders a couple of similarly sized alternatives.)
This pentagonal, or diamond-shaped insert is said to float more inside the tire volume, allowing the tire to flex & move unrestricted at low pressures, while still always being in place to protect against pinch flats. The Panzer liner is made of high-density, closed-cell foam with a smooth finish that allows sealant to move around freely within the tire volume without absorbing or collecting much sealant.
The new gravel liner uses a slightly higher density foam than the mountain bike versions to account for the use of narrower tires. Another big plus is the ability to more safely ride out on a flat or cut tire that can’t be patched or sealed with regular sealant. Panzer says that after refining something like 70 prototypes for their original MTB tire liners, they were able to dial in the Panzer Gravel with around 7 generations to get the material, shape & width perfect for high volume gravel tires.
