GUP (GÜP Kwiki) Quick Fix Bicycle Tire Sealant and Inflator; for mountain bike, road and cyclocross bike; seal and repair flat or punctured tires; works on tubeless tires, tubes and tubular tires.

  • PERFECT FOR RACING: GUP’s custom speed adapter top allows you to repair a flat tire fast and effectively to get you back on the trail or onto the race course within seconds and much faster than changing a tube. GUP’s eco-friendly, non-corrosive, ammonia free, foaming latex-based sealant injects straight through the valve w/o removing the valve core and seals standard 2mm diameter punctures. Depending on conditions, it will stay liquid form for roughly 30 days within tubeless tire.
  • WORKS WITH TUBELESS, TUBE, AND TUBULAR TIRES: Capable of working with all major tire systems and both PRESTA or SHRADER valves. Inflates standard 27.5×2.35 MTB tire to around 35psi and road tires between 90-100psi. After being applied, GUP’s solution will help prevent and repair additional flats while in liquid form. ANOTHER USE: The 125ml/4.2fl oz canister has enough pressure to set tubeless tires beads onto a rim while cleanly injecting sealant into the tire. WORKS ON ALL MAJOR TIRE SIZES
  • LIGHTWEIGHT AND EASY TO USE: GÜP is only 122grams, which is LIGHTER THAN MOST TUBES. Simply insert the valve into the SPEED ADAPTER and press up on the canister to start the flow of sealant and propellant, wait until canister has emptied, clean and close valve, spin the tire to coat the inside, and depending on puncture, it should be sealed. GUP recommends ONE CANISTER PER WHEEL and it is a ONE-TIME USE application. Easy to put in packs/attach to bike using GUP’s HOLSTER (sold separately)
