if i were to buy the Minoura thingy, do i have to attach the bike using the QR axle supplied?
only ask as my SS and MTB both have 10mm through axles. can i still attach them to the trainer?
I've got an older version of tht minoura and would recomend it, it's much quieter than my old cyclops MAG trainer, and has more resistance, setting 3-4 out of 7 feels like a flat road to me so can pedal allong in a normal gear. IIRC minoura's resistance units are largely unchanged inside for donkeys years, they just alter the mass of the flywheel between cheep/expensive models.
You can either used the supplied QR, or most shimano ones fit IIRC (as the levers off center), KCNC/HOPE etc don't work very well or at all. The supplied ones fine though to leave on the bike, just a bit heavier than nicer ones.
Trainerroad.com is (IMO) brilliant, going off HR is pointless as at a costant 20min effort it took 8 minutes for my HR to plateau, and percieved exertion varied massively, the first 5 miutes seem easy, as did the last 5, the middle 10 are agony. Without a power measurement I'd hav gone off way too quickly, and done nothing in the middle and tried to compensate towards the end. To begin with all Turbo's feel really easy, it's after a few minutes of trying to maintain that (initialy apparently easy) effort that it gets really hard work. you can get a similar effect with a cycle computer as power is proportional to speed squared on the turbo, so maintaing a constant speed will be a constant power.
