Built for the landing, not just the jump
Dirt jumping beats up whatever is inside the tire. Every hard landing, every casing, every dusty case puts a shock through the tube, and a rubber tube that is too thin will not take much of that before you are walking back to the car. The Reinforced Dirt Tube is the TPU tube for riders who land first and ask questions later.
It keeps the weight benefit that makes TPU tubes attractive, but the construction is beefed up where jumps punish equipment. That is the difference between this and a race tube: it is built for repeated impact, not just for spinning up fast.
What makes it different
- Reinforced TPU structure built to handle repeated takeoffs and hard landings
- Better resistance to impact stress than a standard tube
- Still lighter than most heavy-duty butyl options, so the bike does not get sluggish
- Holds air through aggressive sessions
- Packs down small when you need to carry a spare
- Works on jump bikes, dirt setups, park bikes, and freeride builds
- OEM and wholesale options for shops and brands
Where it earns its keep
- Dirt jump bikes
- BMX dirt riding and jump lines
- Pump tracks and skateparks with park bikes
- Bike parks and jump trails
- Urban freeride
- Hard training sessions that would flatten a thinner tube
For shops and brands serving the dirt market
TUBENOX builds tubes by discipline, not one tube for everything. Customization covers private label branding, tube colors, valve selection, retail packaging, product labelling, and distributor packaging. We work with brands, distributors, importers, and OEM customers worldwide.
TUBENOX makes TPU tubes for BMX racing, dirt jump, freestyle BMX, MTB, gravel, and road, so if your product line spans several disciplines, you are dealing with one factory that understands all of them.
