In reply to Joao. You're mixing up the Felt IA 2.0 with the original Felt IA. Original is slower, and that's the one I was referring to...

"For example: assume you had only the Specialized Shiv S-Works and Felt IA to choose from for a TT race in Bologna. You know you want more of an advantage on the decisive and steep climb, so you pick the Specialized Shiv S-Works even though the Felt IA is ranked slightly better overall." I believe this is incorrect since s-works takes one more second that Felt IA in the Alpe du Zwift and 16 in the flat. So Felt is better in all scenarios

In reply to Eric Schlange.

Yeah I was right now doing a chart of your top-performers (at least “The most aero setup (frame+wheel)”, “Tron” and “the best climbing road bike”) with the most aero TT Bike (so cadex with disc), the best rolling TT Bike (cadex with balanced wheels), and the best climbing TT bike (Felt With climbing wheels).
And then I realized I can’t do it, cause I can’t “steal” the datas as you didn’t test the TT bikes with wheels.
Would be great if you would do that. I think this 6 data points I mentioned would be enough!

I’d love to see a comparison over gravel (Road to Ruins is every now and then a WTRL TTT route).

In reply to roemer van toorn.

If you’re talking TT, that simplifies things somewhat, at least in my mind.

It’s about trading off climbing performance for flat/descent performance. Figure out what % of your time is spent on climbs vs everything else, then pick the frame that balances it best.

For example, on Bologna, basically 50% of your time is on the flats, 50% on the climbs. So your best frame would be one with equal and high values in the “Frame Time Improvement, Stacked” chart.

So which frame, wheels to choose if you regularly drive mixed roads with climbs and flat? I find it hard to see with this data. I never Zwift only flat, but always mixed (New York I go up, London, Watopia), etc.

In reply to J. Pennarun. We've tried to measure this, but haven't been able to spot a difference. It's hard to measure it super-accurately within Zwift, though, so it's possible there's a slight difference.

Curious about one thing : as slower frames produce more drag, do they also provide better shelter to the riders drafting it ?
