Precautions/Notes:
1. Carbon components have excellent strength properties, but are delicate to impact. If, while riding a bicycle with a carbon drop bar, you fall, or hit the drop bar hard against a tree or an obstacle then you should inspect the drop bar for damage removing the bar tape if needed. Even minor cracks in the outer layer of carbon indicate significant damage on the inside. It is not safe to ride such a drop bar.
2. Do not drill the holes for internal rooting by yourself. It is not safe.
3. Do not store carbon parts in direct sunlight for long periods of time.
4. Make sure that clamps on your stem don’t have any sharp edges. Due to the difference in material hardness, sharp metal edges can act like a guillotine and cut into the carbon tube under load. All edges must be rounded with a radius of at least 1 mm. This prevents localized stress points and avoids damage to the carbon fiber.

Mounting Instructions
1. To install your Rool drop bar please follow the instructions for your stem installation.
2. Apply carbon grease to the clamping area to prevent carbon parts from sliding.
3. When installing brakes, shifters and stem, refer to the max torque parameters indicated in the technical specification above.
Max stem torque (4 M5 screw) - 4 N*m
Max shift/brake lever torque - 3 N*m
