CushCore has expanded their mountain bike tire insert line with an eMTB-specific model. It’s based off the the Trail insert launched in April, but with more aggressive protection to handle the extra weight and forces that e-bikes produce.
The fluted design allows for progressive support in corners…push harder and they’ll work harder to keep the sidewalls supported, giving you the extra traction from lower tire pressures without squirming or bottoming out.
They say the foam material also reduces vibration so you’ll feel less trail chatter at the bar, and finish each lap fresher. Which is good, because with the e-bike’s assist, you’re probably doing more laps anyway.
Flow channels keep the sealant moving around so it can reach holes in the open space, and their air valve notch keeps it sitting flat on the rim’s bed. Specs are:
- Wheel Sizes: 27.5” and 29”
- Tire Sizes: 2.3” – 2.8”
- Inner Rim Widths: 22mm – 35mm
- Weight: 27.5” = 281g / 29” = 299g
- Price: $80 each / $160 set
- Available: August 2023
Joining the new eMTB insert are four new colors shown top right – silver, titanium, purple, and oil slick. That makes 10 colors total for their insert-compatible valve stems, which retail for $25/set ($30 for oil slick) and come in 44mm and 55mm lengths.
