Frequently Asked Questions

How does the D1x work?

Think of the D1x as shifter – similar to the mechanical shifter that’s on your handlebar right now – but programmable, flexible, and simple to adjust.

At the heart of the D1x is a servo that pulls a small length of shifter cable to move your derailleur to get your chain into each gear on the cassette.

The D1x is fully programmable. So instead of a ratchet mechanism in your mechanical shifter, you have the ability to set the D1x to work with any number of gears, and on any derailleur-cassette combination. Gone are the days of pull ratio and barrel adjusters. 

You setup the D1x using a simple configuration app on your smart phone or tablet. Set your shift points, configure your settings, and hit the trails. 

How do I install the D1x?

What is the difference between a Micro-adjust Remote and a Standard Remote?

Starting with the D1x Trail the micro-adjust feature has been moved to the remote. With a Micro-adjust Remote you can fine tune each individual shift point while you ride. Stoked!

What’s the battery life?

The new D1x Trail has updated battery management technology that gives an astounding 80 hours of runtime in normal mode and up to 150 (!?!) hours in low power mode. When the system starts up an LED shows the approximate battery level of the shifter and remote. Green means go, red means charge after this ride, and flashing red means charge before you go. 

What is Low Power Mode?

With Low Power Mode you get all of the same awesome shifting performance but half the power consumption. The drawback is that Auto-shutdown and Get Me Home Gear are disabled. Also, the green flashing LED on the shifter is turned off to… save power.

Get Me Home Gear?

When the system senses that your shifter battery is critically low it will move into the gear you select in the app as your GMHG and leave you there while it powers down. This is meant to be a mid-cassette gear that you can use to safely pedal home.

What do the LEDs mean?

  • Red flashing LED means the shifter is looking for a connection – either the phone or remote can connect and control the shifter.
  • Green flashing LED means the shifter is connected and functioning properly.
  • Orange flashing LED means you’re either in micro-adjust mode or you’re trying to pair with a remote.

How do I turn the remote off?

The remote turns off automatically when it senses that the connection with the shifter is broken. You can turn your remote off by turning off the shifter and waiting a few seconds. The LED on the remote will flash green for 15 seconds and then red twice to indicate it’s shutting down. You can also just take out the battery from the remote, that’ll kill the power quickly.

Will this work on my … drivetrain?


Can I install this on a ….. bike?

The most important consideration when installing the D1x is space on the chain stay for the shifter. You should check that you have adequate linear space along the stay that is clear of any cable bosses or curves. You’ll want approximately 6 inches of space to get good placement.

Can you hack my shifter?

Yes – take precaution by not saving your ATM pin, SSN, or library card on your shifter.

Is it waterproof?

The electronics in the shifter and remote are coated to protect against water damage should water sneak in. The enclosures are sealed and welded shut so the chance of water sneaking in is fairly low.

Obviously, there’s one large hole in the shifter where the shifter cable comes out so excessive submersion of the shifter is not advised. Excess water and mud in the drive tunnel can cause the motor to wear out prematurely.

What is the operating and storage temperature of the unit?

Battery charging: 0°C to 45°C
Operation: -10°C to 50°C
Storage: -20°C to 40°C
Note: Do not store the lithium ion batteries at lower than -20°C for longer than 6 months.
Note: Discharging the lithium ion batteries at low temperatures will negatively impact battery life.

What kind of batteries do you use?

The D1x ships with 14500 and 10400 protected lithium-ion batteries. You can get replacements from the Archer store online. 14500 cells are AA size, 900mAh capacity, 50mm long and 14mm diameter. 10400 cells are AAA size, 600mAh capacity, 44mm long and 10mm diameter.

You can also get replacements from vendors elsewhere but be very careful to get the correct sized cells. Some vendors sell unprotected li-ion batteries that do not have overcharge and over-discharge protection circuits – this is dangerous. Seriously.

Further some other vendors sell 14500 and 10400 batteries that are slightly larger than the batteries that fit in the D1x. Using these larger batteries can break your shifter and ruin your day.

Last thing I’ll say here, some vendors sell batteries with crazy high capacity ratings that seem too good to be true. We’ve done tests on batteries from many vendors and have found that the high-capacity cells are often not as powerful as they say on the package. Stick with the D1x batteries that we sell and you can’t go wrong.

What kind of warranty do you offer?

1-year guarantee against manufacturing defects. Contact for warranty issues.
