Zefal mountain bike frame protector

Zefal down tube armor MTB frame protection – perfect for road bikes

Protect your bike frame with the Zefal Down Tube Armor, a durable shield designed to safeguard the down tube, chainstays, and all vulnerable areas of the frame structure.
Originally made for mountain bikes, this protection is also perfectly suited for road bikes, offering long-lasting resistance against debris, impacts, and friction.

Product description

Specifics & benefits

Reinforced down tube protection

The Down Tube Armor shields one of the most exposed areas of the frame, preventing damage from high-speed riding or rough roads.

Ideal for carbon frames

The specialized adhesive won’t damage the frame paint and is perfectly suited to carbon tubes, which are more sensitive to impacts.

Increases frame longevity

By protecting the frame surface, it helps extend the bike’s lifespan while keeping its original finish intact.

Easy to install

No technical skill required—just clean the down tube and stick the protector for optimal adhesion.

Excellent for road bikes
