FAQs

What tools do I need to install these shifters?

You'll typically need a set of Allen wrenches, cable cutters, and possibly a screwdriver. A cable tensioning tool is also helpful.

Can I use these shifters with a 7-speed drivetrain?

No, these shifters are designed for 8-speed drivetrains only.

Are these shifters compatible with all types of bikes?

They are compatible with bikes that have braze-on downtube shifter mounts. Ensure your frame has these mounts.

How often should I lubricate the shift cables?

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

What is the lifespan of these shifters?

The lifespan depends on usage and maintenance. With proper care, they can last for many years.

How do I adjust the cable tension?

There is usually an adjustment barrel on the shifters or derailleurs. Turn the barrel to increase or decrease tension until shifting is smooth.

Where can I find replacement parts?

Replacement cables and other parts can be found at most bike shops or online retailers.
