If you are an avid rider there is a chance you have been stranded at one time or another thanks to a small puncture in your tube, or tubeless setup that did not seal. Gup is a eco-friendly, ammonia free foaming latex based sealant that is there when you need it and out the way when you don't. Grab the Gup Velcro Holster and secure your tube to your bike until it''s called upon.
