The Ultra Light, Extra Durable Bicycle Tube. For A Long Time, The Innertube Has Been Overlooked In The Bicycle Industry. We Will Change That. Our Vision: The Perfect Innertube - Street, Trail Or City - Developed For The Optimal Cycling Experience.Features:Lightweight: - 2/3 Lighter Than A Standard Tube Every Gram Counts, When It Is Up To Cycling Fun. Even More If You Reduce The Rotational Weight.- Tubolito Offers An Easy And Achievable Weight Tuning.- We Can Provide This Solution, As We Are Combining A New Material With A Self-Developed Production Technology. Applying This Technology Allows Us To Build An Innertube That Weighs Only 45 Grams At Our S-Tubo ProductTough: - Stronger As Standard Tubes Lighter And More Robust. We Make The Impossible Possible.- We Can Solve This Contradiction By Using A New Concept: We Are Manufacturing The Innertube With A Thermoplastic Elastomer, Called Tpu. This Group Of Materials Is Known For Its Durability And Excellent Damping Abilities. It Has Replaced Many Rubber Products In The Automotive And Pharma Industry Already.- It Was Our Goal To Transform The Excellent Material Characteristics Into An Outstanding Bicycle Product. We Achieved That By Reducing The Number Of Contact Areas And Kept The Seams To A Minimum.S-Tubo-Bmx: - Lightest And Smallest Bmx Tube Worldwide- 80% Weight Savings Compared To Standard Rubber Rubes- Tested From And Developed With World'S Best Bmx Riders From All Disciplines, Such As Uci World And European Champion Irina Sadovnik- Low Weight Makes High Jumps And Bar Spins A Piece Of Cake- Low Rolling Resistance As The Decisive Competitive Edge- The Main Difference Between Tubo And S-Tubo Is The Wall Thickness. Tubo Products Have A Thickness Of 0,3 Mm, While S-Tubo Products Only Have A Thickness Of 0,15 Mm. For Comparison: A Sheet Paper Usually Has A Thickness Of 0,1 Mm.- These Differences Entail Different Characteristics: Tubo Products Are Twice As Robust Against Punctures As Standard Tubber Tubes. While S-Tubo Products Are Sill As Robust Agains Punctures As Standard Rubber Tubes, They Convince Through Smallest Packed Size, They Convince Through Smallest Packed Size, Low Rolling Resistance And Low Weight.Specifications:- Diameter: 20- Weight: +- 39 G- Tyre Width: 1.5-2.5- Valve: 40 Mm Schrader
