One third of the GreenGuard is made from recycled latex products. The anti-aging sidewall endures the typical overloads caused by insufficient air pressure much longer before it develops ugly cracks.

The most important sizes have been tested and approved for e-bikes up to 50 km/h (E-50).TECHNICAL SPECIFICATIONS: Size: ETRTO 40-559 (26x1.50 inch) Type: Wired Compound: Addix Version: GreenGuard Colour: black reflex Seal: Tube G: 730g Pressure: 4.0-7.0 bar (55-100psi) Load: 100kg EPI: 67 Electric bike: E-25 Profile: HS420 ART.NO.: 11100145 EAN: 4026495627573
