FAQs

Do I need to cut my gear cable?

No, you do not need to cut the inner gear cable. You will need to cut the gear cable *outer housing* to install the adjuster in-line.

Can I use these with mountain bike shifters?

Yes, they are compatible with most indexed mountain bike systems, though they are particularly optimized for Road STI levers due to the finer adjustment needs often found there.

How much adjustment do these offer?

They provide a range of fine adjustment suitable for micro-tuning gear indexing, typically enough to compensate for cable stretch or minor environmental changes.

What tools are required for installation?

You will need a cable cutter to cut the outer housing. Beyond that, standard Allen keys or pliers might be helpful for initial cable routing, but no specialized tools are required for the adjuster installation itself.

Will these affect my bike's aerodynamics?

The design is ultra-lightweight and compact, meaning any aerodynamic impact is negligible for most cycling applications.

How many adjusters are included in a pack?

Each pack contains two M Part Compact In-Line Cable Tension Adjusters.

Troubleshooting

Difficulty turning the adjuster.

Ensure the cable outer housing is fully seated and not kinked. Clean any grit or debris from the adjuster threads and apply a small amount of lubricant.

Gears still not shifting correctly after adjustment.

Verify that the inner cable is properly seated at the derailleur and shifter. Check for any binding in the cable housing or obstructions. The adjuster may need to be set to its neutral position, and the main cable tension re-evaluated.

Shifting is vague or inconsistent.

Ensure the adjuster itself is not loose. Check that the outer cable ends are securely fitted. Clean and lubricate the inner cable and housing.

Pros and Cons

Pros

  • Allows for quick micro-adjustments to gear indexing while riding.
  • Easy to install for home mechanics, requiring no special tools.
  • Lightweight and unobtrusive design.
  • Improves shifting performance, especially on road bikes with STI levers.
  • Enhances the usability of indexed gear systems.

Cons

  • Requires cutting into existing gear cable outer housing.
  • May add a slight amount of complexity to initial cable setup.
  • Not ideal for very old or non-indexed shifting systems.
  • Can be a small additional point of failure if not installed correctly.

Setup, Compatibility & Care

Setup:

  1. Identify the gear cable outer housing that requires adjustment.
  2. Carefully cut the outer housing at the desired location using a cable cutter.
  3. Insert the M Part adjuster into the cut.
  4. Slide the supplied outer cable end caps onto the ends of the outer housing, securing them to the adjuster.
  5. Route the inner gear cable through the adjuster and reconnect to the derailleur.

Compatibility:

  • Primarily designed for indexed gear systems.
  • Highly recommended for use with Road STI levers (e.g., Shimano, SRAM).
  • Compatible with most standard bicycle gear cable systems. Ensure your cable outer housing diameter is standard.

Care:

  • Keep the adjuster mechanism clean and free from dirt and grit.
  • Periodically lubricate the threads if significant adjustment is needed in adverse conditions.
  • Inspect the adjuster and surrounding cable housing for any signs of wear or damage.
