BarHugger Posted June 18, 2014 Posted June 18, 2014 Some say listening to eye of the tiger while doing HIT gives you an extra 20Watts mahala...I will test Not some say.......its been "scientifically" proven.........just a pity you can't race with it......for "Jou Blixem" and "Oom Piet"........

V12man Posted June 18, 2014 Posted June 18, 2014 mmm ok - but why? The rolling resistance when in the deadspot of the pedal stroke is higher on an IDT than on the road - just a theory... but the math works out pretty close. There are probably a few contributing reasons, like localised muscle temperature etc.

So, will qrings/o'sym be easier to ride on IDT and then it proves that the elliptical rings does somewhat work?

Genuinely clever thinking. In the same vein as when you relax on the IDT it doesnt freewheel much and then takes more effort to get going again compared to on the road?

So, will qrings/o'sym be easier to ride on IDT and then it proves that the elliptical rings does somewhat work? I think it might be easier to do the reverse - increase the rolling resistance on the road by doing a test on a gradual hill - say 6% - now where is one of those for say 40km....... Having been a biopace oval ring user, I would say maybe - but... I didn't like the way the biopace rings made my knees feel...

Exactly - so to find the equivalent hill for your IDT at a specific resistance setting, you need to match the time to decelerate from say 30kph to zero during a freewheel on the road to the time taken on the IDT - should be easy enough to do - just find a steeper hill if the road time Is longer - bit of experimenting should get you in the ball park pretty quickly.

In the same vein as when you relax on the IDT it doesnt freewheel much and then takes more effort to get going again compared to on the road?I agree, but that addiitonal effort would result in extra power being read by the crank base data point so the net result would be a higher output and not lower?
christinejvr Posted October 21, 2014 Posted October 21, 2014 I also consistently get lower power readings (about 10%) when on the IDT compared to on the road. Power output measured with a PowerTap (although different ones) for both IDT and outside. Can the lower readings on the IDT be caused by some loss of power at the point of contact between wheel and flywheel (because of a small degree of slipping)? I can sort of imagine this as an explanation for a hub-based powermeter, but not crank-based.

There are probably a few contributing reasons, like localised muscle temperature etc. any reference to the "math" that you are talking about? I'm quite interested in this topic, would be good to have some more reading. without thinking about it too long, it doesn't seem right that the dead spot should have higher rolling resistance on an IDT compared to riding outside...
