Does flywheel inertia really matter? I’ve read conflicting information on this forum and others that it does/doesn’t make a difference. GP Lama made a video saying the muscles will engage at different points in the pedal stroke depending on the relative speed of the flywheel. I, like all of us using…

First, you have to understand the initial reason flywheels were added to trainers. They are meant to improve “road feel”. While we are pedaling and rolling as we ride outside, the mass of our body and bike rolling along create a certain feel at the pedals. This is due to Newton’s 1st Law, objec…

Ive done a bit of high inertia training, and low inertia training on my kickr. What I noticed immediatly was when spending a lot of time doing lowish inertia training (50 / 28), the large fast group rides I really struggled putting out big power for a long time, and the constant surging nature of t…

Thanks fellas!!! I really do appreciate the advice! I think I’ll keep it in the big ring for the majority of the time and bounce around the cassette to switch it up every now and again.

Honestly it is possible you might get more results on the trainer by working on your aero position with a helmet. Here is one indisputable fact - for the same change in resistance, the little chainring has a higher torque multiplier which allows faster acceleration for the same pedal force. Put ano…

For what it’s worth I have found when using Power Match that using the smaller ring gives a better result. When using the big ring I found I was constantly chasing the power with massive increases in cadence. The TR support team suggested I use the smaller ring as the inertia of the Fly Wheel was to…

Just understand that riding big ring little sprocket will be less responsive to wattage changes compared to little ring large sprocket due to intertia of the faster flywheel.
