The Tannus Tubeless Lite was designed to provide crucial rim protection to XC mountain bikers and gravel riders alike. For mountain bikers, the Lite offers rim cushioning without compromising the tire's natural ride feel, making it the perfect insert for those who want a natural feel while protecting their rims. For Gravel, the Lite, at 40 grams per insert, enhances rim protection while also allowing lower tire pressures. Effectively creating a smoother ride and peace of mind Does not absorb tire sealant Discipline: XC & Gravel Thickness: 10mm Weight: 50 grams Includes tire insert for one wheel Ribbed Design: The new ribbed design is the basis for the Fusion system. When combining the Lite and Pro , the ribs lock into place to ensure zero rolling friction between the two inserts. Rim Protection: Tannus comes in three different thicknesses—the Lite at 10mm, The Pro at 20mm, and the Fusion at 30mm. Tunability: Removing Pro from your Fusion creates the Lite. Reduce your weight while maintaining sidewall stability and rim protection. Increased Traction: Tannus tubeless tire inserts allow the rider to use lower tire pressures. Lite provides rim protection so you can ride worry-free at low pressures
