We currently only produce the white Porcupine in 2.4" width.
TPI stands for threads per Inch. It defines the number of threads contained in one inch of the tire casing. The lower the number of TPI, the larger the gauge cords in the casing. Thus, the more durable the tire becomes. The higher the TPI, the more lightweight the tire becomes and the more supple the ride of the tire. The majority of our tires are 60 TPI, and our race tires are 120 TPI.
Butyl inserts are pieces of butyl rubber wrapped around and placed in between the two overlapped 60 tpi layers, midway through the sidewall in our 2-ply casings. The inserts add strength to the sidewall and add stability to resist pinch flats.
Our current portfolio of tires is produced in Thailand.
Tubeless tires allow you to run lower air pressure without having to worry about pinch flatting a tube. This allows for maximum traction because you have more surface area contact with the ground.
Sealant fill level depends on many variables, most importantly personal preference. For best performance, we recommend the following quantities:
Road/Gravel 30-50 ml | 1-2 oz
26 MTB 60-80 ml | 2-2.7 oz
27.5 MTB 80-100 ml | 2.7-3.4 oz
29 MTB 100-120 ml | 3.4-4 oz
Our tubeless sealant easily lasts the lifetime of a tire, or 8 months. However our internal tests have shown live spans way longer than that.
Depending on your riding conditions, the sealant can get thicker over time, in this case it can be topped up with a bit of water to get the original consistency back.
Our tubeless sealant is water soulable and can easily be washed off when spilled. Make sure to rinse off your clothes quickly to avoid drying up of the sealant. When dry, the sealant becomes strong and super difficult to remove from clothing.
Our tubeless sealant was especially designed to be compatible to work well at high pressures and is therefore perfectly suited for road bike tires.
Can you mix it? Yes. Do we recommend it: No.
Some sealants are similar in composition, however it is hard to tell or monitor what other manufacturers are doing. Mixing sealants could result in an unwanted chemical reaction, leading to the sealant potentially losing its sealing and durability properties. For maximum performance, we 100% recommend using one type of sealant in the tire.
Yes, our tubeless sealant works with all brands of tubeless tires. To be sure, please follow your tire manufacturer’s guidelines regarding the use of sealant.
For optimal performance, we recommend using our stated quantities. However, this amount forms a basis and can be adjusted according to your requirements. For additional protection, we recommend adding more sealant.
If you are a true weight weenie, you can also use a mix of our sealant and 20% water. Our tubeless sealant has a thick consistency to cover the tire the best way possible – this however adds weight. Using a mix makes the sealant more fluid and therefore enables you to add less sealant to your tire.
Yes, you can add sealant to your tubes, as long as they have a removable valve core.
To guarantee the best possible sealing of tubeless tires, tubeless sealant is required. In addition to a perfect seal without any air loss, tubeless sealant also works as puncture prevention by filling cuts and holes up to 6 mm.
ONZA tubeless sealant is compatible with CO2 cartridges.
Our sealant is water soulable and can easily be washed out of your tire with water (given it has not dried up).
The blister is made of polypropylene and can be recycled as plastic.
The zip ties are made of polyamide and can be recycled as plastic.
The outer packaging is made of cardboard and be recycled as such. The zip bag is made of polypropylene and be recycled as plastic.
Tubes are made of butyl and can be disposed of in the household waste. Alternatively, you can send your defective tubes to the Schwalbe Recycling Program. The valve and valve nut are made of metal and
can be reycled as such.
The bottles and cans are made of high-density polyethylene (HDPE) and can be recycled as plastic.
The best way to dispose of liquid tubeless sealant is to soak it up with some piece of household paper and put it in the household waste. Dried-up tubeless sealant can be disposed of in the household waste directly.
