Description
A tube failure mid-moto usually means a flat tire and a long walk back to the truck, which is the exact scenario ProTaper Heavy Duty Tubes are built to prevent. The 120/100-18 tube in this line is made from ultra-high-grade natural rubber, chosen for the flexibility needed to seat correctly against the bead while still resisting the punctures and pinch flats that come from rock strikes, roots, and hard landings. Wall thickness is increased over a standard tube and the construction is seamless, closing off the weak points where cheaper tubes tend to split first.
Why racers carry these:
- Ultra-high-grade natural rubber for flexibility with strong puncture resistance
- Seamless build with increased wall thickness for added durability
- Reinforced valve stem to resist stem failure during hard impacts or tire changes
- Sized 120/100-18 to match the equivalent ProTaper off-road tire
- Suited to motocross, technical off-road trails, and long enduro days alike
Install with talc or a dedicated tube lubricant to reduce friction against the tire casing during mounting, and torque the rim lock down evenly so the tube is not pinched on one side. Running low pressure for extra traction is common in off-road riding, and this is exactly the situation where a standard tube gives up first; the added wall thickness here is built for that use case. Confirm the 120/100-18 sizing against your current tire before checkout. IPD Racing keeps these in stock as a companion part to the ProTaper tire lineup.
