The legend lives on. The latest generation of the Marathon has a new tread pattern, new puncture protection, new sidewall and new compound. Its well-known qualities have also been improved - higher mileage and better puncture resistance.
KevlarGuard: The Kevlar belt has been improved. Not only is the protective layer both stronger and safer, but we also succeeded in making the material considerably more flexible.
The result: The level of protection is higher, while the rolling resistance is lower!
This tire also has a SnakeSkin sidewall protection for more resitance against sidewall abrasion.

 

The 635 ISO is a European size that is fairly rare in the United States. Please check the tires you currently have on your bike to make sure you need this size. On the sidewall of the tire you will find a set of numbers in the format (xx-xxx). This is the width-diameter in millimeters. If the last number is 635 then this is the correct tire for you. If it says 630 or 622 please select another tire. We list the ISO size in parenthesis at the end of the product name on our site.
