Thanks for this Ben. I'm going to have to try it for myself as soon as I get the chance.
STEEP SLOPE ISSUE
One for you Bill, you may be able to do an experiment for me.
I am also riding in the BKool Odense 'Januar 2016' league and with all my effort in the Goats and Chaingang I was getting behind so today I had a go at the Mortirolo and guess who was there as a ghost, no other than a Pro BillS.
I had no intention of killing my self today having worked hard yesterday so I thought you may act as a beacon for me in one way or the other.
Off we went and there was some familiar exchanging of positions as the gradients went up and down until the gradients got stupid, 45%, 30 something % and some other 25's and over.
At the first one you were off so I thought never mind I'll gain some ground on the less serious slopes but because there were so many steep/steep bits you were half way in the stage when I was only a quarter way.
Luckily I had the league stage results board open on the screen and I could see there were plenty of folk in the 30 something minute time and the slowest was 59 minutes.
At quarter way through the stage I was on 15 minutes so I guessed it was going to take me an hour to finish so I had nothing to gain by going on as far as league placing was concerned other than the 5%.
When I was going up a 45% I was down to 4kph and I checked this with Bike Calculator and it was about right.
In fact while I was riding I kept the calculator open and checked various gradients and they all pretty much checked out OK with my speed.
Also, because I have been 'playing' with my trainer I have left the covers of for now and at 45% the magnets were fully in the circumferance of the flywheel so in summary I believe my BKool Classic can simulate 45% slopes for me as registered on BKool at 77kg but it was probably at its limit. I have seen pictures of a broken Pro Trainer and the inards are literaly the same with about the only differnce being the fan and fan housing so I guess Pros can do 45% ass well.
Sprinting from this to do the on/off style was a no go as when I went faster the restistance went up propotionaly with the speed of the flywheel as stated before re eddy current braking.
I therefore stopped, saved what I did and went for a steady climb up Ventoux instead at pretty much 350 watts all the way.
Below are the speed and power graphs for the first 5.3 km which I did for you, me, the Odense League Stage leader (on a pro) and the fastest Classic contender other than Valverde who has locked his data.
Could you possibly go to my ride and challenge me (if you can becuase I did not finish) and do the first 5.3 km again but this time when you see the first 45% coming try going into it real slow, 4 kph if you can, and on the next one do your own thing and see what differnce it makes.
Also do this with some of the other 20% plus climbs if you can.
What I am hoping to see is that if you go into the steep slope dead slow you will also end up at 4 kph but if you don't it is possible that they have written a slope limit into the latest trainer firmware, that I cannot download as stated before, in order to try and level the playing field for us BKoolers when we go up against the 'average other trainer' which may be more slope limited. For this they may have chosen the average slope limit or just generalised it in the market range but obviously not 7%.
If this is so I am stuck in a world on my own where I will not be able to compete on extreme courses but in the real world road racing very rarely goes up anything steeper than 20% and certainly would not go a 45% as you would probably have to walk it and if it was wet that may prove impossible in raceing shoes and perhaps even socks.
