Continental, with the depth of experience developing tires for bicycles, cars, and motorcycles, has also worked with sealant for years. They developed their Revo Sealant based on that knowledge. There are two sizes available 240ml and 1000ml. Revo sealant will work with tubulars, tubed clinchers, and tubeless clincher tires. The fluid is both ammonium and protein free, so it shouldn’t be a problem regardless of tire, tube, or rim you’re using. If you’re filling a 700c tire or tube, 30-60ml of sealant should do. If you’re using mountain bike tires, here’s a simple guide: 2-2.1” 80-100ml, 2.2-2.3” 100-120ml, 2.4-2.5” 120-150ml. The bottles are marked on the side so you can install the correct amount. It’s also worth noting that Continental recommends pulling 10cm of one bead off the tire and installing the sealant there rather than through the valve.
