The Marathon Efficiency Evo tyre is a state of the art touring tyre that sets the standard for protection and durability.* Sporty design and high versatility* High-quality technology that has been tried and tested by professional athletes in World Cup races* Schwalbe's fastest touring tyre to date with the lowest rolling resistance increased battery range for e-bikes thanks to ADDIX Race Compound and Super Race casing* Very good puncture protection thanks to V-Guard and three-layer carcass construction on the sidewallThe V-Guard Puncture Protection is made of a specifically developed hi-tech polymer fibre that is also used for bullet-proof and stab-resistant vests. It provides excellent protection from cuts and punctures, and at the same time, it is extremely lightweight. Neither the rolling resistance nor flexibility of the tyre are compromised by the V-Guard.With the new Super Race construction, we are also setting new standards in suppleness - no other carcass glides so silky smooth over the ground, and thus providing traction, like Super Race does.* Tyre Type: Folding tyre* Profile: HS 617* Performance: Super Race, V-Guard, SnakeSkin* Rubber Compound: Addix Race* Thicker woven carcass: 67 tpi* Maximum capacity: 132 kg* Weight: 795g**ETRTO:*** SCR1994: 40-622* SCR1994A: 50-622* SCR1994B: 55-622* SCR1994C: 55-584* SCR1994D: 60-584* SCR1994E: 55-622
