It has uploaded to their servers Bill, same as mine did, but it isn't showing up on our time lines for some reason? When I try to challenge you from this page it gives an error same as mine did. No idea what has happened, but I have sent a couple of 'very annoyed' mails as well!

Darryn. What is that page and how do I find it? I didn't think it showed anywhere on bkool that I'd done the ride.

Here -> http://www.bkool.com/profile/detail/141076?durationType=DISTANCE&lapCount=1
It is the main page of the session file where you can select your bots and ghosts to ride with you..

It is now showing Geoff's ride uploaded, but now if I challenge him by clicking on his avatar it doesn't give the error page, so it seems his ride has been saved straight to his history page.
I'm expecting our rides to turn up in a few days, a run that I did on the 6th has just appeared today as well...they must have serious backlogs or something on their servers, no idea why it does this,but its very frustrating, especially after a ride as hard as that one!!

Thanks Darryn. I'm not convinced my rides will ever show up as I've had a few that never did. I never did figure out the bots and ghosts page so I'm still fairly rubbish at using the bkool software.
I think bkool need to issue an instruction on what to do if a ride doesn't show. I think I'll suggest that to them.

Well I have a lead which I plug in but never get a peep from Bsim, ah well it seems to work fine as far as I know...maybe they were sneaky with the late Classic's and they update via the Usb+Ant like the pro :biggrin:

I also have V2.15

Not a bad shout. I've emailed bkool to see if they have updated the classics to take the usb port out.

That's good news Pedro!
Gotta be honest, when mine turned up, nothing worked as it should until they logged in to my pc with teamviewer and re calibrated everything. Now its all good, not sure and cant comment on accuracy compared to Garmin or any other brand of power cranks, but it is consistent, which for this price is more than adequate for my purposes.

How did you get them to do that?

Put my teenager on the turbo today, he did well for a lazy 16 year old. He weighs in at 57kg, it was a down hill route, I thought he did well and he instantly went to Amateur 4 :thumbsup:

They're calling me on Friday to remote into my system and take a look.

I'm pretty sure now that my resistance unit is very poorly calibrated, as my new Powertap passed a static weight test perfectly and reads about 80% of the power the Bkool reports on every run I've tried, no matter how I set it up.

My Bkool seems to give the same figures as you guys at 10mph, 20mph, etc. on the flat, and since those who've tried it with their power meters (a powertap and a KICKR with built in power meter) also show the same, I'm left with the only conclusion being that the resistance the unit is not putting out the resistance it should.

I would say that the bkool software calculates how much resistance is required depending on assumptions for aero drag, rolling resistance and your programed weight, any wind, gradient, etc. and then tells the unit to apply the level of resistance required. Since my powertap speed agrees perfectly with the speed/cadence sensor and the bkool speed display, I seem to be doing the 10mph, 20mph or whatever, but if the actual power being produced is c.20% less than the bkool display, the only answer can be that the resistance bkool is using in it's calculations is not actually being delivered to the wheel. There is no way for the bkool software to know that the correct resistance is being applied, as it has no inbuilt power meter, it just uses speed and resistance to calculate the power figure, and if the resistance is wrong, the power figure will be wrong. Another advantage of the KICKR, which has a power meter built in.

So if they calibrate it properly, the resistance will get stronger and I will have to pedal harder to maintain the same speed, bringing up the power figures on the powertap to match the bkool calculations.
Then I'll no longer be able to keep up with you lot, but will excuse myself by claiming that all your trainers are poorly calibrated ... :banghead:

So if you suddenly see me demoted back to Amateur you'll know they've fixed it!

Sounds like a big difference if there is a 20% discrepancy!
I just base it on my FTP testing done at the university hospital being 312watts for an hour with a HR curve according to the power, and the BKool is now basically giving the same HR to Watt comparisons after they calibrated.
For me this is fine as it means my training zones are as good as the same from both tests. I use HR as my main input during training anyway as this usually decides if I am going too hard and risk the dreaded lactate explosion in the legs!

Hmmm.. Interesting. I must admit I'd rather see higher power figures than lower. In reality though I'd like to see everyone on a level playing field the most. I think my unit is typical in the way it's calibrated but it sometimes gives me real trouble with fluctuating power figures. It can sometimes drop 100w without me feeling like I've reduced my effort. FTP tests are a disaster as I just can't make the power I can going up a steep hill and it goes up and down like a yoyo.
