We all love to stop and smell the roses, but like they say, every rose has its thorn. And as we all know, there's no better way to ruin a beautiful ride than with a thorn in the tube. No need to worry, though, because we designed our Thorn-Resistant Schrader Valve Tubes to combat pesky pricks of all shapes and sizes. Starting at the basis of the construction, we designed the tube to be thicker at the outer side (the part against the tire) in order to stop pesky bits from puncturing all the way through the tube. Then, at the inner side (the part against the rim), it's actually thinner in order to reduce weight. This way, you don't have to sacrifice performance in the name of protection. - Thicker construction on the outer side (against the tire) enhances puncture protection. - Thinner construction on the inner side (against the rim) maximizes weight savings.

Our new 2Bliss Ready Tire Sealant was custom-designed in partnership with a leading laboratory for tire sealants, and it also underwent extensive real-world testing with our Factory Athletes. What we developed is an innovative, ecological formulation that's the answer to the requirements that riders like you've been demanding. It will immediately seal punctures up to 6mm, whether it be on a road or mountain tire, as well as across global temperatures [-20° to 70°C]. Natural, micro holes in the sidewalls will seal well, and the system is safe for use with latex inner tubes, even inside tubulars. Please note that this sealant is ammonium-, protein-, and latex-free, so it holds no potential for allergic reactions, and there's no risk of it creating damage to bike parts. - Proven by our Factory Team Athletes. - Seals punctures up to 6mm. - Performs in a wide temperature range (-20° – 70°C). - Works in latex inner tubes inside tubulars. - Ammonium-, protein-, and latex-free, so there's no risk of allergic reactions or damage to bike parts. Recommended sealant amount per tire: - Road: 24-32mm - 30-40ml - Open Road: 33-50mm - 50-70ml - MTN: 2.0-2.3" 80-100ml - MTN: 2.4-3.0" 100-125ml

The Problem Solvers Presta Valve Extenders add 33 to 50mm of length to your tube or tire valve so that it protrudes far enough out of deep-section rims so that you can attach your pump. These lightweight, durable aluminum extenders simply screw onto your Presta valves by hand.
