The next time your tire goes flat, you might be reaching for a can of GÜP. Meant to be a quick fix for flats in tubed or tubeless tires, GÜP is a new product from a company based in SoCal. By combining the sealant with the inflator, the GÜP Kwiki claims to be an all-in-one solution that will get you back on the road or trail in a jiffy.

Sold in 125ml cans, GÜP includes a silicon “speed adapter” that supposedly prevents you from needing to remove the valve core for presta valves, and it works with schrader valves as well.

Adding the sealant and inflating the tire simultaneously is fairly simple, and the foaming latex sealant is said to work on up to 2mm cuts in tubes or tubulars, or 4mm cuts in tubeless tires. With enough volume to fill a 29 x 2.4″ tire to 29psi, and enough pressure to work for road tires as well, the canister comes in at 122g.

If you purchase the Hölster for an additional $3.49, you can easily strap the canister to your bike for easy access.

Each individual can sells for $14.99, or you can order a six pack for $90 (which is oddly $0.06 more expensive). While that’s pretty pricey for an individual flat repair, the convenience might be worth it if it works as advertised, and if you send in five used cans, you’ll get one free.


  1. It’s quite funny how governments, advocacy + environmental groups etc. etc. the world over proclaim that the bike is the most eco friendly mode of transport and are in turn pushing it to the masses as the way forward in cities.

    Then on the other hand, we have stuff like this being pushed out by the bike ‘indistry’, that yes, while convenient, are complete environmental nightmares. All that ‘packaging’ for a one shot fix where a spare tube can be used and reused (and reused and reused depending how thrifty you want to be). And as the can is filled with residue goop, recycling it may not even be an option.

    Ok, changing a tube may be slower but at least it teaches you to pull whatever it is in the tyre casing that caused the flat out before putting a new tube in. I aint no greenie but c’mon….

    Plus, there’s no way I’m strapping that to my frame!

    • To be fair, I don’t think tubeless MTB tires on gnarly terrain is really proposed as a commuter or transport solution.
      More likely, most people’s MTBing involves driving distances to go riding the forest; thereby increasing CO2 emissions.
