Hi everyone. This will be a bit long winded so bear with me please…
I’m an experienced triathlete and cyclist and have been competing for quite a few years now.
When we went into lock down due to the pandemic I got a Tacx Vortex wheel on trainer off a mate of mine to use on Zwift as we couldn’t get outside on the bikes. I’ve more or less ridden it every day and have seen massive improvements in power. For reference I kept the Tacx Vortex calibrated to within an inch of its life…Tyre pressure and roller pressure exactly the same, every ride without question. Re calibrated it regularly etc etc. I’m very strict about things being accurate!
I’ve just bought a Wahoo Kickr Core (brand new) last week. Calibrated it before riding it and I’ve seen an instant increase in my power when racing. I thought something isn’t correct here!!! So I did the ‘factory spin down’ and I am having the same results. I am putting out power “easier” on the Wahoo then I did on the wheel on trainer. I’ve been told in the history of the world no one has every switched from wheel on to direct trainer and see a power increase.
All I can put it down to is the Kickr has a big freewheel which helps the pedal stroke and is just a better, smoother piece of kit to use. Where as the Tacx was a pig to ride at anything above 270 watts.
Has this happened to anyone else?
