GUP Sealant

The canisters include a latex-based formula which can simultaneously inflate and seal most common punctures quickly.  Works with tubes, tubeless, and tubular tires.  Proven to seal up to a 6mm puncture on tubeless tires, getting you back in the saddle faster.  Enough pressure to seat a tubeless tire onto a rim–an enduro racers dream come true.  Fills a 29 x 2.4 MTB tire up to about 29psi.

125ml canister of GÜP comes with an easy-to-use hose adapter and both Schrader and Presta valve compatible threaded nozzles

Had a small thumb tack puncture my rear tire and went flat on my Aventon Sinch. Used Gup and pumped back up and have ridden hundreds of miles with no problems. Awesome product

Got a flat tire while I was riding my adventure 3 on trails. The GUP worked great and was able to get back to the car and patch the tire. GUP is awesome
