Schwalbe Marathon Plus Reflective Tyre A growing number of us at the Bike Co-op have been relying on Schwalbe Marathon Plus Tyres as our everyday treads for over a decade. The reason is simple. Schwalbe Marathon Plus Reflective Tyres are the most puncture-resistant pneumatic tyres we've tested. The fact that they are also smooth rolling yet exceptionally grippy in all weathers make Schwalbe Marathon Plus probably the ultimate urban / utility / hybrid / touring bike tyres. Schwalbe's flexible, 5mm-thick SmartGuard sub-tread effectively deflects the sharpest thorns and shards. Combine the Smart Guard sub-tread with Schwalbe's Endurance tread and you have almost a centimetre of protection between the road and the inner tube. Despite this awesome protection, the Schwalbe Marathon's low rolling resistance makes it quiet and smooth running. This Endurance tread is very sure footed - even on wet, gravelly towpaths. The tyre's reflective sidewalls make perfect sense on a city bike. The tyre's wide recommended pressure range (typically 50-85psi) allows you to select your preferred comfort level. Approximate weights: 740g (700x28), 800g (700x32), 895g (700x35).
