Conti Tube 400/450 x 18 Heavy Duty TR4 (120/130/140) Continental (CT18400HD)

This heavy-duty inner tube is engineered specifically for demanding conditions where extra protection against punctures is required. The increased wall thickness makes it an ideal choice for riders tackling rougher terrain or off-road tracks.

• Heavy-duty construction significantly increases resistance to pinch flats and external debris.
• Fitted with a heavy-duty TR4 valve that stays secure during aggressive acceleration and braking.
• Made from a specialised rubber blend that retains air pressure longer than standard tubes.
• Provides additional damping characteristics to help absorb sharp impacts from rocks and roots.
