Verified PurchaseMountain BikeGame changer for mountain biking!
I've been using KAIJA Tire liners for 6 months now on my fat bike. Zero punctures even on the roughest trails with thorns and sharp rocks. The installation was straightforward and they've stayed perfectly in place. Worth every penny for the peace of mind.

Living in Minnesota, I deal with a lot of debris on winter roads. These liners have completely eliminated my flat tire problems. The dragon scale texture really does grip the tire well - no shifting or bunching after hundreds of miles.
Alex Rodriguez
Verified PurchaseRoad BikeGreat protection, slightly heavier
The puncture protection is excellent - I've hit glass and nails with no issues. Only downside is the added weight, but it's a fair trade-off for the reliability. Installation took about 30 minutes per wheel.

Installed these before a 3-day bikepacking trip. Hit a massive thorn patch that would have ruined the trip, but the KAIJA liners held up perfectly. My riding buddy got 2 flats in the same section. These are now permanent on all my bikes.
