FAQs

What tools are needed for installation?

You will need basic tools such as Allen wrenches, a cable cutter, and possibly a cable crimper. Professional installation is recommended if you are unfamiliar with bicycle mechanics.

Can these shifters be used with a 9-speed drivetrain?

No, the SL-R400 shifters are designed for 8-speed drivetrains only.

How often should I lubricate the shift cables?

It is recommended to lubricate the shift cables every few months, or more frequently if you ride in wet or dirty conditions.

What type of frame is compatible?

These shifters are compatible with frames that have braze-on downtube shifter mounts.

Where can I find replacement parts?

Replacement cables and other parts are available from most bicycle shops or online retailers.

How do I adjust the cable tension?

Use the barrel adjuster on the shifters or the rear derailleur. Turn it clockwise to increase tension and counter-clockwise to decrease it.

Troubleshooting

Shifting is not smooth or precise.

Check the cable tension. Adjust the barrel adjuster on the shifters or derailleur. Ensure the derailleur is properly aligned with the cogs.

Shifters feel stiff or difficult to move.

Lubricate the shift cables and check for any obstructions in the cable housing. Replace cables if necessary.

Gears skip or don't engage.

Check the rear derailleur alignment and hanger. Inspect the chain and cassette for wear and tear.
