Stan's NoTubes

Race Sealant

In the midst of a race, there's no time to stop and putz with a leak. Stans developed their Race Sealant to work faster and better than their standard sealant, so you can carry on and catch the lead pack. With twice the grit of their standard, the sealant better plugs larger punctures to keep you rolling. The Race Sealant also functions better in a wider variety of temperatures and conditions, saving you from the dreaded dry sealant situation on the side of the road.
