FAQs

Is this part compatible with ST-6800 shifters?

No, this clamp band unit is specifically designed for the ST-6700 series and may not fit later generation shifters.

What tools are needed for installation?

You will typically need a standard hex key (Allen wrench) and a torque wrench to ensure proper installation.

Does this come with mounting bolts?

The Y-6SC98150 is the clamp band unit designed for use with the existing hardware of the ST-6700 system.

Can this be used on carbon handlebars?

Yes, but ensure you use carbon friction paste and do not exceed the handlebar manufacturer's torque limits.

How often should I check the clamp tightness?

It is good practice to check your cockpit bolt tightness during your regular monthly maintenance routine or before a long event.

Troubleshooting

Shifter rotates on the handlebar

Verify the bolt is tightened to the correct torque specification; consider using a small amount of carbon paste if mounted on carbon handlebars.

Clamp bolt is difficult to turn

Remove the bolt, clean the threads, and apply a fresh layer of anti-seize or lightweight bicycle grease.

Setup, Compatibility & Care

To install this unit, ensure that your handlebars are clean and free of debris. Position the clamp band correctly around the handlebar, ensuring the shifter body is aligned to your preferred reach and drop angle. Use a calibrated torque wrench to tighten the bolt, observing Shimano's recommended torque specifications to prevent damage to carbon handlebars or the clamp threads. For maintenance, periodically inspect the clamp for signs of oxidation if riding in wet conditions, and ensure the bolt remains tight during routine bike service. Always use a light application of bicycle-specific grease on the bolt threads to prevent seizing.
