Question: how much sealant in 29 tire?
Answer: For a XC 29er tire we recommend 3-4 ounces (89-118ml) of sealant. The amount of sealant can be adjusted based on the volume of the tire. More sealant can also be added if a tire is porous and difficult to seal. For road and cyclocross tires, we recommend 2 ounces (60ml).
