• Carbon Care: Carbon components require specific care. Avoid clamping the handlebar in areas not designed for clamping, and use carbon-specific assembly paste if recommended.

Package Contents

Your Zipp SL-70 Ergo Drop Handlebar package should contain the following:

• One (1) Zipp SL-70 Ergo Drop Handlebar

Note: Additional components such as stem, brake levers, shifters, and bar tape are sold separately.

Setup and Installation

Proper installation is critical for the safety and performance of your handlebar. If you are unsure about any step, consult a professional bicycle mechanic.

1. Prepare the Stem: Ensure your stem's clamp area is clean and free of debris. If using a carbon stem or a carbon handlebar with an aluminum stem, consider applying a thin layer of carbon assembly paste to the clamping surfaces to increase friction and reduce the required clamping force.
2. Position the Handlebar: Carefully place the handlebar into the stem clamp. Ensure the Zipp logo is centered and facing forward.
3. Align and Tighten: Adjust the handlebar to your desired angle. Begin tightening the stem faceplate bolts evenly, following the manufacturer's recommended torque sequence (usually a criss-cross pattern). Use a torque wrench to tighten all bolts to the specified torque value (typically 5-6 Nm, but always refer to your stem manufacturer's specifications).
4. Install Brake Levers/Shifters: Mount your brake levers and shifters onto the handlebar. Position them ergonomically for comfortable reach and braking. Tighten their clamps to the manufacturer's recommended torque.
5. Route Cables: The SL-70 Ergo handlebar features external cable routing. Secure brake and shifter cables neatly along the handlebar using electrical tape or cable ties before wrapping with bar tape.
6. Wrap Bar Tape: Starting from the bar ends, wrap your chosen bar tape tightly and evenly, overlapping slightly to cover the handlebar surface. Secure the ends with finishing tape.

Operating and Usage

The Zipp SL-70 Ergo Drop Handlebar is designed for road cycling, offering multiple hand positions for comfort and control.

• Top Section (Flats): Provides an upright and relaxed riding position, ideal for climbing or cruising.
• Hoods: The most common riding position, offering a balance of comfort and control, suitable for general riding and light climbing.
• Drops: Offers an aerodynamic position for high-speed riding, descending, and aggressive cornering. The ergonomic bend provides a secure grip.

Ensure your bike fit is correct to maximize comfort and performance with this handlebar. Adjust saddle height, fore/aft, and stem length as needed.

Maintenance

Regular maintenance ensures the longevity and safety of your Zipp SL-70 Ergo Drop Handlebar.

• Cleanliness: Keep the handlebar clean. Use a soft cloth and mild soap and water. Avoid harsh chemicals or abrasive cleaners, especially on carbon surfaces.
• Bolt Torque Check: Periodically check the torque of your stem faceplate bolts and brake/shifter clamp bolts. Loose bolts can lead to component slippage or failure.
• Inspect for Damage: Regularly inspect the handlebar for any signs of cracks, deep scratches, or impact damage. Pay close attention to the stem clamp area and where levers are mounted. Carbon fiber can fail catastrophically if damaged.
• Bar Tape: Replace worn or damaged bar tape to maintain grip and comfort. This is also a good opportunity to inspect the handlebar underneath.
