The Overdrive Excel features SilkShield for puncture protection and durability and a dual compound tread design to make the perfect economical trekking tire. Along with all its other great ride qualities, the Excel has a reflective stripe on the sidewall, keeping you visible at night for city riding. If getting a reliable, high-performance trekking tire at an economical price is what you're after, the Overdrive Excel is the tire for you.
Two different rubber compounds are processed into a tread strip. The arrangement of the compounds is planned according to the desired properties of the tyres.
Wire bead core
The bead core must hold the tyre securely on the rim. High-quality wire is very well suited for this - the disadvantages are: Not foldable and somewhat heavier (approx. 50g more).
SilkShield provides Silkworm protection all round, from rim edge to rim edge, preventing cuts and other defects on the sidewalls and under the tread.
