The Tharsis 3Five Handlebar[paid link] is a high-performance carbon handlebar designed for aggressive riders who demand precision and durability. Whether you’re installing a new set or maintaining an existing one, proper setup and care are crucial for both comfort and performance. This guide will take you through installation, adjustment, maintenance, and troubleshooting to keep your handlebars in top condition.

Tools Required

Before you start, gather the necessary tools:

  • Torque wrench[paid link] (recommended for precise tightening)
  • Allen keys[paid link] (typically 4mm, 5mm, and 6mm)
  • Carbon grip paste (for improved friction and reduced torque requirements)
  • Cleaning cloth and isopropyl alcohol (to clean clamping areas)
  • Calipers or a measuring tape (for accurate positioning)

How to Install the Tharsis 3Five Handlebar

Step 1: Preparing the Stem and Handlebar

  • Ensure the stem clamp area is clean and free of any dirt or grease.
  • If you’re using a carbon stem, apply carbon grip paste to the clamp area to reduce the risk of slippage and prevent over-tightening.
  • Check the maximum torque rating (usually printed on the handlebar or stem) and do not exceed it during installation.

Step 2: Aligning and Clamping the Handlebar

  • Insert the Tharsis 3Five Handlebar[paid link] into the stem and align it based on the markings on the bar.
  • Hand-tighten the stem faceplate bolts in a cross-pattern to ensure even pressure.
  • Use a torque wrench[paid link] to tighten the bolts to the manufacturer’s recommended torque (typically 5-7 Nm for carbon bars).

Step 3: Attaching the Controls and Grips

  • Install the shifters and brake levers, ensuring they are positioned comfortably within reach.
  • Use a torque wrench to secure them without over-tightening, as excessive force can damage carbon bars.
  • If using bar tape or grips, make sure they are evenly wrapped and secured.

Adjusting the Tharsis 3Five Handlebar for Optimal Comfort

Finding the Right Angle

  • Rotate the bar slightly up or down to find a position that supports a neutral wrist angle.
  • Ensure that the drop and reach measurements align with your preferred riding style.

Setting Brake Lever and Shifter Position

  • Position the brake levers so they are easy to reach without straining your wrists.
  • Shifters should be positioned close to your fingers for quick and easy gear changes.

Checking for Symmetry

  • Use a measuring tape to ensure both sides of the bar are aligned evenly with the stem center markings.
  • Check alignment by placing the bike on level ground and eyeing the bar position from the saddle.

How to Maintain Your Tharsis 3Five Handlebar

Routine Cleaning and Inspection

  • Clean the handlebars with isopropyl alcohol and a microfiber cloth to remove dirt and sweat buildup.
  • Inspect the clamp areas for any cracks, stress marks, or delamination, especially if you’ve experienced a crash.
  • Avoid using harsh chemicals that can degrade the carbon finish.

Checking Torque and Security

  • Every few weeks, check the torque on stem bolts and lever clamps to ensure nothing has loosened.
  • If you notice any creaking or movement, inspect the clamping surfaces for dirt or wear.

Troubleshooting Common Issues

Handlebar Slippage

  • If your Tharsis 3Five Handlebar slips while riding, first check the stem clamp torque and retighten if necessary.
  • Apply carbon grip paste to improve friction and reduce the need for excessive torque.
  • If slippage persists, inspect the stem faceplate for uneven clamping or damage.

Creaking or Unusual Noises

  • Remove the handlebar and reinstall it after cleaning the stem clamp surfaces.
  • Ensure all bolts are tightened evenly and to the correct torque.
  • If the noise persists, check the handlebar for internal damage—a faint crack can sometimes be the cause.

Frequently Asked Questions

1. Can I cut my Tharsis 3Five Handlebar to adjust the width?

Yes, but only if the manufacturer explicitly allows it. Use a carbon-compatible saw and ensure both sides are cut evenly.

2. What’s the maximum torque for the Tharsis 3Five Handlebar?

The typical torque rating is 5-7 Nm for stem clamps and 4-5 Nm for lever clamps. Always check the manufacturer’s recommendations.

3. How often should I check my handlebar for damage?

Inspect it every 2-3 months, especially after crashes or heavy impacts. Look for cracks, stress marks, or delamination.

4. Is the Tharsis 3Five Handlebar compatible with all stems?

It’s designed for 35mm clamp diameter stems. If your stem is a different size, you will need a compatible replacement.

5. How do I improve comfort with the Tharsis 3Five Handlebar?

  • Adjust the angle and reach for a neutral wrist position.
  • Use high-quality bar tape for extra cushioning.
  • Ensure your brake and shifter positioning is ergonomic.
