The Schwalbe Green Marathon HS620 represents the absolute benchmark in environmental sustainability for demanding cyclists. This revolutionary tire combines the legendary GreenGuard puncture protection with a closed-loop production cycle: the world's first bicycle tire made with 70% recycled or renewable materials, it incorporates carbon black from recycled tires (rCB) and 100% Fair Rubber, while reducing pollutants by 98% and the CO₂ footprint by 34%.

Technical Overview

The Green Marathon in 700x44C size (44-622) combines legendary robustness with radical eco-responsibility. Its modernized HS620 profile offers total versatility for urban bike commuting as well as long-distance cycle touring. At 860 grams, this wire bead tire guarantees easy installation and unfailing reliability, even on fast e-bikes up to 50 km/h (E-50 certification).

GreenGuard Level 5 Puncture Protection

• 3 mm GreenGuard layer: Insert under the tread in highly elastic Indian rubber, partly from recycling, for particularly reliable protection against punctures and cuts
• TwinSkin Technology: Reinforced sidewalls to resist premature aging and cracking due to insufficient pressure
• 67 EPI carcass: Dense weave offering the ideal balance between suppleness, strength and longevity
• Proven performance: The Marathon maintains its benchmark status for puncture protection and mileage, inherited from 40 years of continuous innovation

Radical Environmental Commitment

• First closed-loop tire: 70% recycled or renewable materials — the only tire incorporating recycled carbon black (rCB) from used bicycle tires
• 100% certified Fair Rubber: Schwalbe pays a fair premium for each kilo of rubber, directly improving the living conditions of small producers and their families
• Massive pollution reduction: 98% fewer pollutants and 34% CO₂ avoided compared to conventional tires
• No compromise on performance: Independent tests confirm rolling resistance equivalent to the classic Marathon, with identical durability and comfort

ADDIX Eco Compound and Rolling Performance

• ADDIX Eco Compound: Optimized compound specially designed for e-bikes and intensive use, offering grip, longevity and energy efficiency
• Low rolling resistance: HS620 profile redesigned to optimize efficiency — Bicycle Rolling Resistance tests rank the Marathon among the fastest in the touring category
• Modern and sporty profile: Updated tread pattern to tackle all terrains, from urban jungle to bikepacking routes
• Adjustable pressure: Range 3.5 - 5.5 bar (50 - 80 PSI) allowing comfort and efficiency adjustment according to terrain and load (up to 109 kg)

E-Bike E-50 Certification and Versatile Use

• ECE-R75 homologation: Tested and approved for S-Pedelecs with assistance up to 50 km/h — maximum safety for fast e-bikes
• E-25 compatible: Also suitable for electric bikes limited to 25 km/h and traditional bicycles
• Total versatility: Designed for city bikes, trekking, cycle touring, daily bike commuting and long-distance travel
• Reflective stripes: Enhanced side visibility for night rides and low-light conditions

Installation and Compatibility

The wire bead facilitates mounting and ensures stable positioning in the rim. This 700x44C format (44-622) is suitable for ISO 622 diameter rims (700C/29") with a recommended internal width of 19 to 25 mm. Inner tube required (not tubeless) — Schwalbe recommends tube references 17, 19, 17AP, 17E, 17E+, 19A or 19AP.
