Incorrect, it also scales the decline value sent to the trainer. Does that not effect speeds on downhills? Maybe it doesn’t, seems like it shouldn’t 
After further thought, I think it doesn’t make a difference for downhill speeds. If you want more resistance on a downhill however then lower trainer difficulty is key… should you want to sprint downhill for example.
The thing it would affect is the resistance you feel when pedalling. So at 50% TD a 10% incline would feel like 5% resistance wise. On the downhill the RESISTANCE you feel is already 50% of the actual number, so you won’t spin out. So a 10% negative incline always feels like a 5% negative incline at 100%TD. at 50%TD that would be reduced to the resistance feeling of a 2.5% negative incline.
However how does that affect speed when NOT pedalling ?!?
And for the record, I was riding at 100% Climb Portal difficulty.
The speed is affected by the power you do (along with your weight, height etc.), not the trainer difficulty. You might be able to consistently put out more power with a higher or lower gradient feel (due to not spinning out etc.), but the speed will be affected by your power.
Absolutely it affects the incline and decline values sent to the trainer but no it doesn’t affect how fast you go up or down. It only affects how much resistance you get when you push on the pedals. So if lower trainer difficulty helps you not spin out on a descent so you can apply more power, then sure you go faster, but absent that power you don’t go any faster.
This auto-steering did not happen today in the climb portal, same route as yesterday. Probably they changed sth. server side.
Check out any Pace Partner doing over 2.0w/kg on Tempus Fugit and it’s busy. Check out those Omer courses and it’s quiet. I agree that they need to be riding with more variety but climbing seems as popular as another bout of COVID.
The solution could be what RGT enabled us to do - ride a course with our own bots.
Ride on.
Dave.
What’s the advantage of riding with your own bot - being able to draft it for greater distance at the same effort? In that case, Zwift could just implement a fake draft mode where air resistance is reduced.
Steady pacing for those who don’t want to use erg mode
But we all know that the current bots don’t do steady pacing anyway.
I opened the pairing screen to run a spindown calibration (kickr core) while waiting for a TT to start. The pairing went fine, but then the resistance was locked to 50-60 watts (aka no resistance at all) until I passed the starting line, which means that I basically started the TT from a stillstand. It may be a bug introduced with this new feature?
Not sure if this bug has been reported but there is a big black flashing square showing up right before turning left to start Box Hill in London. It has been there since the last 2 or 3 firmware updates. It happens every single time I pass there.
black boxes have been an issues for months. Although mostly went away but seems like the later release or two they are returning again for some users
They came back in force with 1.69
Thanks for reporting this - we’re looking into it.
Can someone at Zwift please acknowledge the resistance flywheel feedback issue on KICKR trainers pertaining to primarily ERG Mode when a gradient is encountered and maintaining the cadence at the same power becomes easier going uphill and harder going downhill? This has been around for quite a while and I was glad to see others commenting about it finally. The flywheel feels like it “fights” when efforts are easier and gradient is causing this even though we don’t expect that to have any effect in a workout - but it does.
There are several posts in the 1.68 thread but this has been around since at least 2Q 2022 to my experience.
It still exists in 1.69.
The foundation of this issue seems to be related to “base resistance”. You can shift up into “harder” gears and reduce the effect of it somewhat, but it shouldn’t be that way.
If the effort becomes harder in wattage target, it becomes less noticeable. If the effort is easier like gray or blue zone (for me, this may differ for others), it is much more pronounced. You can easily reproduce it if you set a constant ERG target perhaps around 100-150W, especially in an easier gear, on rolling terrain.
It is also the case of this type of effect when the gradient feel trainer difficulty is scaled to 0 with the trainer difficulty slider in SIM mode.
You can see the variances of cadence following the small bumps in the Big Flat 8 route with this workout tonight. And when the harder efforts hit, the cadence is naturally easier to maintain at a higher level, which can be seen in the yellow and orange efforts.
Investigation of this would surely be appreciated.
It doesn’t matter if it is a group or solo workout.

Over a year now I believe. Doesn’t appear to be a priority to fix it
it’s odd i thought it was pretty much fixed then it started again with 1.69
When do you plan on telling us about changing the XP formula? It’s mind boggling you let a website break the news to your loyal customers who chose to stay after the rate inrease fiasco.
Why do we need a official announcement? It’s happened.
If your motivated by the levels they’re still there it’s just going to take a bit longer to level up now.
