The amount of sealant required is primarily based on the tire width.  Below is a chart of our recommended dosage based on your specific tire width provided in both ISO and standard units.

We have performed an initial compatibility test with many of the major brands available.  There has been no negative interaction observed when mixing OX1 with any of the other brands.  Not to toot our own horn too loudly, but when we have done our internal head to head comparisons we have outshined the competitors in performance.  Mixing with others could reduce the sealing effectiveness.

The purest say yes, but the practicalist say no.  There are some pros and cons to each...life is too short...just replenish and ride like hell!

The sealant life inside the tire is mainly dependent on riding frequency.  The more you ride the more frequently you may need to either replenish or add sealant.  For our performance product, OX1, the sealant is constantly applying a thin film on the tire in search of holes to seal.  You should probably check the sealant level at 300 mile intervals or 3 months, whichever comes first.

A one year shelf life is to be expected if the package is kept tightly sealed.  The product can be stored in a cool place for maximum life.  The OX1 formulation is a higher performance, quicker sealing blend.  For maximum performance it should be used within 9 months.

The OX1 product is useful down to 14 ^oF (-10 ^oC).  You won't catch me riding anywhere near that cold!  In the event you do have an Arctic expedition planned try our OX2 which is useful down to -15 ^oF (-26 ^oC)

Both OX1 and OX2 sealant are formulated from natural latex.  Natural latex is biodegradable.  Synthetic latex products would not be considered biodegradable.  The carbon fiber additives are not biodegradable although we are producing the additive from recylced carbon fibers.
