Product description
The Metzeler MCE 6 Days Extreme Front Tyre 57R 90/100-21" is part of the latest collection from Metzeler.
Features:
- Tread design: Large distance between the lugs: for optimum self-cleaning of mud and dirt, effective braking, Lateral lugs: Cornering stability, lateral grip, optimised acceleration out of corners, Alternating lug geometry: extreme traction and optimised directionality
- Standard Enduro GP set. Specifications: The tread compound made of special polymers and with a high carbon black content is built on a multi-ply stable carcass, which is additionally reinforced by a separate protective layer directly under the tread surface. Most important advantages: This is the winning tyre of the Enduro GP, suitable for demanding racing conditions with extreme mechanical and thermal resistance of the tread.
- MEDIUM rear tyre (3 red tread lines). Specifications: Full carbon black tread polymer with plasticiser additive and a softer carcass than the standard 140/80-18. Main advantages: Suitable for races with a greater proportion of slow and technical sections.
- SUPER SOFT (lime coloured tread lines). Specifications: Tread polymer with a higher percentage of plasticisers than the SOFT version, an even softer rubber with maximum grip even on the most difficult and wet technical sections. Key benefits: A very special product that offers excellent performance and durability compatible for 1-day races. The ideal range of use starts at a few degrees above 0°C. (Colder operating conditions lead to poorer performance). Prolonged use at high speeds on the road at all temperatures is not recommended.
- SOFT (3 orange-coloured profile lines). Specifications: Lower compound hardness, adequate lug stiffness and abrasion resistance. The specifications are maintained at all temperatures. Important advantages: The SOFT specification is suitable for slower and more technical cross-country trails, even in wet conditions.
- EXTRA SOFT (3 white profile lines). Specifications: Treads with high hysteresis for excellent performance under extreme conditions in different temperature ranges. Main advantages: Outstanding performance and durability compatible with 1-day racing events in the toughest conditions and even without momentum. Developed in combination with METZELER MOUSSE IP: 9253200 E-18H1-SOFT (FLAT) and IP: 9338100 MOUSSE E-18H1-SUPER SOFT (the SOFT simulates an equivalent air pressure of approx. 0.3 bar).
