Hi guys, so I sold my bkool pro and bought a wahoo kickr... My gosh I can't even do anything past 6 percent climb now, getting trounced downhill all the time and having to push well over 360 watts just to try and keep up to someone on a bkool pro when just on the flats.. Anyone else had this when using a wahoo on bkool?
I got my KICKR back before Christmas and also found it at a disadvantage to the Bkool trainers in the Bkool software.
I don't know about 6%, but certainly the climbs got a lot harder above around 10%, on the Bkool Pro it seemed to top out much past 10-12% and you could just "push past the resistance", whereas with the KICKR it would keep getting harder right up towards 20%. Chasing Bill up a 18-20% incline on a KICKR was an exercise in futility (and humiliation) ...
Getting trounced downhill was something I also got used to, as I soon discovered that unlike with the bkool trainers, the Bkool software did not simulate freewheeling at all on a KICKR and gave no gravity assist (no blue speed figures).
I complained bitterly to Bkool but they just said that "feature" was not available on the KICKR. How can say they "fully" support the KICKR then have such a fundamental difference in implementation that basically made it impossible to keep up with someone on a Bkool trainer? I was actually tempted to buy a Bkool Classic just for the multi-user leagues ...
I haven't used the KICKR since the start of April, due to health "issues", but I did wonder if they had eventually levelled the playing field, but I guess not!
On the flat I estimated the KICKR had something like a 10% disadvantage over my previous Bkool Pro, as it more accurately simulated the resistance and did not over estimate the power being put through it. I used a power meter to measure the Bkool and it was always at least 10% over estimated, on climbs sometime as much as 20% or more. The KICKR was much closer to the power meter readings, as it has it's own power meter built in. So even on the flat, you're having to work 10% harder or so.
The KICKR is a great piece of kit, much superior to the bkool, but if using the bkool software is your main focus I would always recommend the bkool trainer, especially as they now have the ANT+ control to allow occasional use in trainer road, etc.
Funnily enough, after a few months using the KICKR I found my power levels came back up to where they were on the Bkool and then exceeded them considerably. For training purposes, the KICKR seemed to give better results, I guess due to the better resistance control.
So if the aim is to improve your power and climbing abilities, the KICKR is the best, just get used to being thrashed on moderate or steep climbs, any downhills and on the flat as well!

I'll have to rest and do it as late as possible this evening !
