Crank doping
Maybe it's just on the Garmin Vector 3 that I have?
Yep I have often thought that would be an easy way to artificially boost your recorded power numbers - just put in a much longer crank length. Hopefully that info gets beamed to Zwift whilst recording.
Luckily, the max error I can have is 172.5/170 (1.5%) if I ever forget to amend it. It doesn't usually cause me a problem as I have 2 sets of pedals. One is usually on the turbo (bike has 172.5 cranks) and one is on the road bike (170 cranks). It is only if I use my winter bike that I have to start thinking.
