AMB's notes: Ride Mechanic Hoop Goop has been designed, tested and made in Australia. It's aim is to seal punctures quickly, and even be used as a sealant to add when you have a puncture, to ensure it's always fresh. This means a dry setup, with 60mL added through the valve stem if you puncture. It's more efficient, and prevents sealant drying out in your tyre. Both of the punctures slowed their air release very quickly, with a full seal taking the noted time. This is represented in a fairly modest overall pressure loss. A Dynaplug or Stan's DART would be a smart move for a larger hole for security (that goes for any larger puncture). After the two puncture repairs, about half of the 100mL required for the 2.4” tyres was left, with no signs of separation. Larger 940mL bottles are available, but the 235mL has been designed to be enough to set up two wheels, with none leftover to dry out on your workshop shelf. The 940mL bottles work out at about $6.30 per wheel, or even less if you choose the 60mL repair option.
