Doesn't everyone know that on flat pure power is better than w/kg, I thought this was pretty common knowledge. The issue is that there are very very few flat race courses on zwift and so w/kg really is as important as we think. a rider with a ftp of 250 but weighing 5kg less than another of ftp 250 will dominate on any climb that there is. Add into this that aero benefit is lessened on steeper climbs so the heavier rider can't gain a free pull up a climb. Road to A is correct and used various routes to prove it.
I don't think they do. There is so much focus on wkg and the forums are full of complaints about losing to lower wkg riders (without factoring in absolute power or torque) Stable power is great for an iTT or Hill climb, but what if you need to accelerate. How many riders can produce 100Nm of torque at 80 to 100rpm? But yep, you're absolutely right about climbing. If the road turns up for any sustained duration, then wkg wins out. But caveat, it depends on the length and gradient of the climb. A heavier rider can carry momentum through a short bump.
bro... I'm 116 kgs.... w/kg matters if you want to climb ANYTHING. on the flats its definitely harder to drop me. but put a freakin bunny hill on any course and i'm dropped immediately. Personally, because I love cycling and know I'll never be good at it, it's required I change my goals. I just don't ride the bicycle to "go fast" or to "win a race"; I ride because it's fun... and it is a great lifestyle.
@@pasqualified Yep, taking about flat routes with a few bumps here and there. e.g. Watopia Flat route. When climbing at speeds below 30kph, gravity becomes the dominant opposing force, power-to-weight ratio in this scenario is important for sustained climbing. Interesting that you notice a speed difference at 1kg. That's the difference between a carrying a full water bottle and riding without one. I was only 3% faster at 10kg lighter. Do you know how much faster you are with that weight difference?
Absolutely. And that was a 10kg difference between riders. 1 or 2kg is going to be negligible. Just remember, 🍕🍕🍔🍔🍟🍟🌭🌭🌮🌮 won't help you set a PB on the Alp Du Zwift. 😄
@@stevej_on_a_mtb But if someone like me would lose 25kg, from 90 to 65 it would be a little more, but on the flat not worth it. I would probably be flying up those hills though, but thats another story.

oh and losing even 1-3 kgs I notice a difference in speed.

@@ptp1969 could you still hold 600 watts for a minute at 65kg. 💪
@stevej_on_a_mtb I have no idea how many watts you lose when dropping weight. But I am afraid I wont be able to ever check. 25kg is a bit much ...
LOL.
