The Wahoo KICKR Snap is on of the premier mid-range trainers of choice. It will definitely SNAP those legs into shape! With a solid 10.5lb flywheel, it is not only a quiet wheel on trainer, but it has a decent road feel also.
As a smart trainer, the KICKR Snap allows you to choose from several different modes and resistance levels, and communicates power and speed data to external applications through the ANT+, ANT+ FE-C (Fitness Equipment Control) and Bluetooth Smart protocols. One of the most impressive features of the KICKR Snap(and some other smart trainers) is what's known as ERG Mode. This mode allows an application like The Sufferfest app to control the resistance of the trainer to match the efforts of structured workouts. Just pick a workout, choose a gear that gives you a straight chainline, and start Suffering. The Minions in the Machine do the rest. And don't even think about cheating on the last 5 seconds of that interval in "Revolver". ERG Mode doesn't play that game. On second thought, maybe they should've called it "AARGH" Mode. If you prefer to control your own Suffering, you can choose one of the standard resistance levels when you connect the KICKR in the Ride Check screen of the Sufferfest app.
The Wahoo KICKR Snap is fully compatible with The Sufferfest app in both ERG and standard modes. If you're having issues connecting the KICKR Snap to the app, the first thing to check is that you have the most current firmware installed on the trainer. You can use the Wahoo Fitness Utility to check and update the KICKR's firmware. You can also go to the Wahoo Fitness Website and validate that you have the Latest KICKR Snap Firmware on your trainer.
Connecting To the Sufferfest App
ERG and Resistance Mode
As we mentioned above, the Wahoo KICKR Snap can connect to The Sufferfest Training Centre app using either ERG ("AAARGH!") mode or Standard mode. You can also complete a "spindown test", which will calibrate your KICKR Snap before you enter a workout. The accuracy of power meters can be affected by both temperature and barometric pressure. Performing a spin down periodically will help ensure that your KICKR is properly calibrated. However, if you do an advanced spin down using the Wahoo Fitness App, then that can be done every 3 months or so.
We recommend at least a 5 minute warm up (unless you do Wahoo's advanced spin down) on the KICKR Snap before you do a spin down test for the most accurate power readings. We also recommend you do your spin down test the same way each time. This will create consistency in your power readings.
The image below shows you where the advanced spin down option is located for the KICKR Snap.
In The Sufferfest Training Centre you can select the Wahoo KICKR Snap for Bluetooth connections on the iOS and Mac App. The Windows App can only communicate through ANT+, so you will need an ANT+ Dongle.
ERG mode will control the KICKR's resistance and Standard Mode will run the KICKR in slope mode just like a standard fluid trainer. Standard mode is useful when completing the fitness test video, "Rubber Glove", which is used to help you determine your Functional Threshold Power (FTP) and Lactate Threshold Heart Rate (LTHR). To view the power curves for each of the standard resistance levels, consult this handy graph from Wahoo.
Is There Anything Else I Need To Know About The KICKR Snap?
There are a few things we need to talk about when using the KICKR Snap. The KICKR Snap adjust resistance according to the speed of the flywheel. If your Sufferlandrian legs begin to fail, and your cadence slows, expect the KICKR Snap to ramp up resistance. We refer to this as the "KICKR Snap Black Hole". Once it begins to suck you in, it is hard to escape (Just like couchlandrian furniture!). We suggest back pedaling for ten seconds while the KICKR Snap slows and resets. This will give your legs the quick break they need and allow you to finish the Sufferlandrian interval that Grunter Von Agony has set for you. If you are finding that you are constantly hitting the "KICKR Snap Black Hole", you may need more rest or you are due for another FTP test.
How Often Do You Do A Spin Down?
You can do an advanced spin down calibration with the Wahoo KICKR Snap once every two to three months. The Minions at Sufferlandrian Services also use the Wahoo KICKR Snap and will shamefully admit we only do a spin down once every 6 months. Rarely, do we even notice any differences with this device. The KICKR Snap is highly reliable.
