TUBLISS inner bladder for system 21''1.6''
The TUBLISS inner bladder for system 21''1.6'' is a replacement inner high-pressure bladder for the Nuetech Tubliss Gen 2.0 tubeless tire system, dedicated to 21" front wheels. It restores the high-pressure chamber that locks the tire bead and seals the outer low-pressure chamber in the Tubliss setup.

- System compatibility: Nuetech Tubliss Gen 2.0 system – 21" front
- Role in system: Forms the high-pressure inner chamber, providing a 360° rim lock and sealing the low-pressure outer chamber
- Operating pressure (inner bladder): Approximately 100–120 psi
- Wheel size: 21" front rim
- Part number: IB21
- System type: For use in the Nuetech Tubliss Gen 2.0 tubeless tire system replacing a conventional inner tube
Service context
This IB21 inner bladder serves as a service part to replace worn, weakened, or damaged high-pressure bladders in the Tubliss Gen 2.0 21" front system. A sound inner bladder is critical for maintaining bead clamping force and for safely running very low outer-chamber pressures (0–10 psi) for increased traction.
Installation and use
The IB21 bladder fits only the corresponding Tubliss Gen 2.0 21" front core and installs as the high-pressure inner tube component; reuse of the existing Tubliss core components is expected, following the standard Tubliss installation and inflation procedure.
What's included
Supplied as a single Nuetech Tubliss IB21 replacement inner bladder for the Gen 2.0 21" system, packaged as a service part.
