SCHWALBE Marathon 406 Racer 20X1.5

Description

The Marathon Racer has a 67 TPI carcass, SpeedGrip compound, RaceGuard puncture protection and LiteSkin sidewalls. Unlike the Marathon and Marathon Plus, the Racer doesn’t have a thick and heavy anti-puncture layer under the tread. On paper, the Racer should have a much lower rolling resistance than both the Marathon and Marathon Plus. Specified weight of the Marathon Racer is just 465 grams, this makes it a lot lighter than the Marathon which has a specified weight of 730 grams. The biggest savings seem to be in the anti-puncture protection. The Racer uses a double layer of thin nylon fabric instead of the 3 or 5 mm thick latex layer the other Marathon tires use.
