Wahoo KICKR Snap
The Wahoo KICKR Snap is a smart trainer that connects to TrainerRoad via either ANT+ or Bluetooth Smart. TrainerRoad can
automatically control the KICKR Snap's resistance in accordance with the workout's profile. This is a wheel-on trainer
that uses its heavy flywheel to deliver smooth power.

[1] Cadence transmitted by a smart trainer is an estimation of your cadence. This may not always be 100% accurate given
potential changes in ride data throughout pedal stroke especially during periods of inconsistent cadence. For best
results, the use of a dedicated cadence sensor is suggested, but not required.
[2] ANT+ USB or key may be required to connect to ANT+ devices.
[3] In order to use Bluetooth on Windows devices, a Bluetooth dongle is required. See more information here.
[4] Cadence is not a feature that the KICKR Snap supports. In order to have cadence with TrainerRoad using this trainer,
you will need a dedicated cadence device.
How to Use Your KICKR Snap
- Choosing Your Connection
- Connect via ANT+.
- Connect via Bluetooth.
- Click here to learn how to pair your devices and adjust device settings.
- Choosing Your Trainer's Mode
- Erg Mode (default)
- Resistance Mode
- Setup
- Calibration
- Perform a Spindown calibration before each ride to ensure that your power is always as consistent as
possible.
- Trainer Pressure
- Rolling resistance (with regards to TrainerRoad) is defined as the amount of pressure on your tire from the
trainer's roller. This is an important variable to keep consistent between rides to keep your training as
consistent as possible. Keep track of how many turns you tighten your trainer onto your wheel and repeat the
same steps each time you remove/install your bike.
- Tire Pressure
- Tire pressure can also affect rolling resistance. Make sure you pump your tires up to the same amount of
pressure for each workout.

KICKR Snap Troubleshooting
Device Dropouts
- Dropouts can be seen while riding as an absence of data. You may be experiencing device dropouts if your data values
drop to zero, or to a null '--' value.
- Why this happens: The most common culprit of dropouts are typically low batteries which cause a weak signal, and
interference from other nearby devices.
- The solution: Click the following link to learn how to avoid device dropouts.
ANT+ USB not recognized

Issues pairing your device
- When trying to pair your device if you're unable to see, or pair your device properly, there may be a connection
issue. This could be caused by a faulty connection with the device or another application may be using your
Bluetooth or ANT+ connection.
- The solution: Click on the following link to learn more about device pairing troubleshooting.
Wattage Floor
- It takes a minimum amount of watts to simply turn the pedals on a bike. This minimum wattage requirement can
increase even more in higher gears. For more information on wattage floor and what it can look like, click here.
- The solution: Change into an easier gear. This will allow your trainer to spin slower thus allowing it to reach
lower power values.
Inaccurate Speed
- Speed readings when riding indoors on a smart trainer are inherently unreliable. The "speeds" riders achieve indoors
are often not representative of speeds they'd be going outdoors at equivalent power levels. Simply put, indoor speed
readings can be misleading and don't add any value to the workout so TrainerRoad does not display them during your
ride. To learn more about speed readings on a smart trainer, click here.
Floating Power / Power Not Following Prescribed Power
- Dropouts can cause your power values to get "stuck" in place and follow a constant power rather than changing with
the workout profile.
- The solution: Avoiding dropouts will help reduce the possibility of this happening.
- Wattage floor/ceiling - If you find that your power is floating above your prescribed power, typically during a
recovery interval, you may be experiencing wattage floor.
- The solution: Change into an easier gear. This will allow your trainer to spin slower thus allowing it to reach
lower power values. To learn more about what a wattage floor is, click here.
- Power smoothing set to too high of a value can give the illusion that your power is not following the target power
when in reality, it is. Power smoothing takes a running average of your incoming power over the span of time that
you have selected in your settings, 1-30 seconds. Your average power over that time span is then shown on your
workout player.
- Common cases - You would notice this at the onset of an interval. When the interval starts, you may notice that
your power is lagging behind quite a bit and then eventually rises to meet the prescribed wattage. This is due
to the running average that's being calculated.
- The solution - To fix this, you may need to lower your power smoothing value in your settings. If power
smoothing is desired, we recommend adjusting your settings to around 4-7 seconds for most workouts. This should
allow you to visually smooth your power while still allowing it to your power to catch up quickly when entering
intervals.
- NOTE: PowerSmoothing only visually adjusts your power during your workout. Only raw data is stored during
your ride. Due to this, you may notice a difference between post, and during, workout graphs.
- ERG Mode Not Set: If your trainer is set to resistance mode (or slope/standard mode with some trainers) your power
will not be automatically adjusted to match the target power. In this case, your power may be graphed similarly to
that of a power meter and float around without following any workout profile.
Resistance Lock-up During Ride
- When pedaling at a low cadence, or if your change cadence during a change in prescribed power, it's possible that
your KICKR Snap can dramatically increase the resistance and prevent you from pedaling as the resistance continues
to climb.
- The solution: Begin backpedaling for around 5-10 seconds as the resistance unit loosens its grip. Then carry on
pedaling.
Tire Slippage
- If you find that your tire slips when pedaling, you may need to increase the tension between your tire and the
trainer.
- Solution: Tighten the trainer contact knob in 45-degree increments until the slippage stops. Also, make certain
that your tire is inflated to the proper pressure as this will help the contact pressure between the two
surfaces.
KICKR Snap Best Practices
Calibration
- For the most accurate and consistent power readings, make sure to perform a spindown calibration before each ride.
- If time allows, the optimal solution would be to perform a spindown calibration after spinning for around 5-10
minutes to warm up internal components and tire to trainer contact.
Update Firmware
- Updating your trainer's firmware to the latest release is very important. Many of these updates contain fixes that
the manufacturer has been working on. Updating your firmware whenever the latest release is available will make sure
that your device is always up-to-date with the most recent features and improvements.
- To update your KICKR Snap's firmware using an Android device, follow the directions found here.
- To update your KICKR Snap's firmware using an iOS device, follow the directions found here
Gearing
- When using ERG mode, follow the gearing suggestions found in our smart trainer modes explained article for best
results.
- If using resistance, or standard/slope mode, you will need to make sure to shift your gears just as you would when
riding outdoors. Doing so will allow you to reach your prescribed target power during your workout.
Tire Pressure
- To ensure that you're experiencing the most consistent training with a wheel-on trainer, make sure to check the
following:
- Calibrate before each ride
- Ensure that your tire is inflated to the same pressure before each ride.
Trainer Contact Pressure
- To ensure that you're experiencing the most consistent training with a wheel-on trainer, you should make sure that
your trainer contact pressure is the same each time that you install your bike on the trainer. When tightening the
roller onto your wheel, once the trainer touches the wheel, turn the knob 2-3 full rotations. Remember how much you
tighten this tension before each workout and follow the same steps each time you place your bike back on the
trainer.
