The Glow Worm Bicycles puncture-free guarantee:
If you get a flat on a Schwalbe Marathon Plus tyre from Glow Worm Bicycles, simply bring it in to our workshop and we will replace the innertube free of charge, for the life of the tyre!
The world famous Schwalbe Marathon Plus is unmatched in its resistance against punctures. The tour version has a tread pattern half way in between a mountain bicycle tyre tread and a slick road tread. It is therefore more suitable if you are going to be riding on a lot of gravel paths. For riding mainly on sealed roads, the standard Schwalbe Marathon Plus is more appropriate.
Glow Worm Bicycles is so confident that this it the best tyre for avoiding flats that we will fix any punctures for free for the life of this tyre. What is its life? Typically around 20,000km depending on how heavy you and your bicycle are, how diligently you keep your tyres and inflated and the surfaces that you ride on. We consider it has reached the end of its life when the blue puncture guard is showing through the tread of the tyre.
