Available in a wide range of sizes from 25/35-622, ContiTPU is premium, light-weight yet durable and suitable for both road and off-road riders.
The highest grade of micrometer-thick TPU deployed across seven sealed layers maximises airtightness and durability. The tubes are uncoloured to further ensure the highest material quality and prevent air retention issues caused by dye-related surface imperfections. Every ContiTPU tube is quality-checked post-production. The base of the valve shaft is slightly conical in shape to improve fit to the wheel rim and reduce unwanted movement, while the valve is internally threaded to allow for the use of valve extensions or a replacement valve core.
We are a Seattle, WA based outdoor gear store with a mission to make climbing, backpacking, skiing & mountaineering accessible and enjoyable for everyone.
