Previously I’ve been using a dumb trainer, my geared road bike, and my P1 pedals connected to my android phone.
I’ve just started trying to use Powermatch with a Tacx Bushido, the same phone and pedals, and my fixed wheel TT bike in erg mode. The gearing was 48x17, but I can try different sprockets (up to 20, down to 14).
I’ve only done one ride so far, but I found that I couldn’t warm up or recover below about 150W without the resistance ramping right up, and it didn’t lock me into a power as much as I was expecting - it’s all over the place.
I didn’t do a calibration of the trainer as I wasn’t sure if a roll down made sense with a fixie. I don’t know if this is a problem with my expectations, my trainer, the combination of the trainer and the fixie, or an issue with the communication between the pedals, phone and trainer being too slow.
Does anyone else do TR with a fixie on a wheel-on trainer in erg mode? What changes should I try to make this work (I really want to use the fixie so I can spend time in my aero position)?
