The Next Level in Sealing Power from the People who Invented Tubeless Conversions If you've walked the mechanics' pits at any National or International level event, chances are you've seen them: trademark Stan's black quart bottles with no labels. Look closer and you might have seen strange symbols scrawled all over the bottles in a silver marker, letters and numbers, formula notes by the man himself, Stan Koziatek. For nearly fifteen years Stan has been quietly formulating a special racing version of our legendary sealant for many of cycling's most successful teams. Working with athletes who push themselves and their tubeless systems to the absolute limit, he developed a proprietary sealant formula with close to twice the amount of the standard sealing crystals plus special "XL" crystals capable of sealing even larger punctures. Stan's Race Sealant's combination of large and smaller sealing crystals interlock to form a lattice work that not only seals but strengthens and reinforces the area of the puncture, allowing for an entirely new level of sealing performance. The quantity and size of crystals in this special formula means that Stan's Race Sealant can only be installed directly into the tire. As a result of its immense sealing capabilities, the Race Sealant will clog injectors and smaller bottles almost immediately. Stan's has made Race Sealant available to riders everywhere, and it is only available by the quart. - First choice of riders around the world for tubeless conversion and flat prevention - Twice the amount of Stan's standard sealing crystals - "XL" crystals capable of sealing even larger punctures - Stays liquid 2-7 months for long-lasting protection - Premium low-viscosity formula resists freezing to work in environments as cold as -30° F (-34° C) - Natural materials, safe for the environment

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.

Specialized's 2Bliss Ready Rim Strips create a secure barrier, from sealant to rim, in a clean, simple to install strip. Mountain bike riders running 2Bliss can now change tires quicker and easier than with any other tubeless system.

The Ventura Presta-to-Schrader Valve Adapter converts Presta valves common on road bikes to Schrader valves, so that any pump will be able to fill your tire. - Adapter for Presta valves - Use a Schrader pump head (American) to fill a Presta valve tube - Brass - With a seal ring

The Product that Started a Tubeless Revolution Inside this simple bottle is a product that changed cycling. Today's tubeless systems rely on the lighter, more reliable, self-sealing performance of Stan's Tire Sealant. Just two ounces of Stan's in a converted standard tire or tubeless tire can repair punctures up to 1/4-inch almost instantly to keep you rolling. Longer-lasting Stan's Tire Sealant is formulated to stay liquid in tires with even thin casings for up to seven months. Arid conditions require more frequent monitoring of sealant levels, but anti-freezing agents in our special formula allow Stan's Tire Sealant to be used in temperatures as cold as -30° F. One quart will convert up to 16 tires. - First choice of riders around the world for tubeless conversion and flat prevention - Seals punctures up to 1/4-inch (6.5mm) quickly - Stays liquid 2-7 months for long-lasting protection - Premium low-viscosity formula resists freezing to work in environments as cold as -30° F (-34° C) - Natural materials, safe for the environment - Can be injected through valve stems with removable cores compatible with tubes and tubular tires

These oversized Presta valve nuts are specifically designed to provide extra clearance and extra leverage to better tighten tubeless valves. They're especially helpful on single-wall rims. -Concave to allow better engagement of the valve/rim interface -Oversize to provide extra torque when tightening -Especially helpful on single-wall rim tubeless setups -CNC-machined AL-6061

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
