Flats are the worst. Even tubeless tires — which thanks to tubeless sealants, have reduced the likelihood of flatting considerably — can be punctured and fail, leaving you forced to add additional sealant or install a tube in order to get home. Sealant dries up over time, which make sealant part of many riders carry for those just in case situation. GUP is a new option that combines two popular solutions into one product: its both a quick fix to leaks and inflation device combined in one.
Designed for use with tubeless, tubular and tubes, GUP is compatible with both presta and schrader valves, making it a viable solution whether you’re a mountain, gravel or road riding cyclist. The latex based contents are under pressure, making it possible to reseat a tubeless tire in the field.
The sealant comes in 125ml canisters and a separate strap is available for holding it on your frame or post. Reports from the field are extremely positive, and while we haven’t had to use it, just having it strapped to my frame brings on a bit of lightweight insurance and piece of mind.
On the Trail
Before dropping in for my run at a local Super D, I unbuckled my waist pack and tossed it into the shuttle, with just the GUP and a multitool, and while that’s a bit light for anything but a relatively short and non-technical run, it’s a welcome addition to my regular ride carry.
The velcro strap holds it secure enough, but I’m also considering adding a bit of rubber to the back of the strap to keep it from moving around in the rough or when I’m pulling my bottle in and out.
While I haven’t had the opportunity to need it yet, (and hopefully won’t for some time) installing it is straight forward, just point the valve straight down in the 12 o’clock position and hold the tip and let ‘er rip. Here’s the instruction video from GUP:
The GUP Quick-fix Sealant & Inflator lists for $14.99 for a 125ml canister and the optional holster strap sells for $3.49. We’ll update this post as soon as we flat with more details.
