2021 Road Bike Stiffness Chart
Moderator: robbosmans
I would trust AX data whenever a third party would test it... I saw numbers from the previous frame that never materialised in a standardised test neither how the frame compared to competition at the time.

The new frame carry more weight, sure, but it's not something that is totally bad. Stiffness to weight has increased and durability is way better.
Some guys had a bit of issues with the first gen (1 and 2) of Vial EVO. I had myself. But the latest holds way better.
I also was under 65Kgs when i used those and maxed out at 85Kgs with the new. I never felt stiffness was lacking even though i was around 20Kgs more.
Luckily i am down to in weight now. The new Ax rides good, it's very nimble and fast steering. Not feeling harsh but not a magic carpet either.
It's like a race bike but with a endurance geo i guess you can sum it up.

No problem mate, glad to help with the chart, I like lab data as well.
But you forgot to add many of them to your chart:
Basso Diamante
Airstreem SL
Basso Astra
BH Ultralight
Corratec Team
Corratec Corones
Cube Litening
Felt FR3
Fuji Roubaix
Ghost Nivolet
Isaac Boson
Haibike Affair
Koga Premium
KTM Revelator
Rose Xeon
Scott Foil 20
Storck Aerfast
STORCK Aernario
Votec VRC
and some bikes tested only for stiffness(not aeroness)
Didn´t they catch your interest?

Well, there are simply too many of them, usually if adding a bike I will also try to investigate the model release year, which sometimes is not that easy (and might not be accurate also ). However, this doesn't mean they will not be added and I can still give some priorities for some models due to requests.Roadrocket wrote: ↑Mon Mar 22, 2021 8:29 pmand some bikes tested only for stiffness(not aeroness)

TOUR only tests the seatpost, I guess the new version S5 has changed its riding geometry so it will be more comfortable? This is something that will not reflect on the comfort score.

Where is Conalgo V3RS?? the 20 champion Tour de France??
the Trek Emonda SLR disc, the BB is very stiff comparing with V3RS and the Cervelo R5 is the mostly high stiffness in the BB, this is for high crazy riders.
For me I recommend the TCR or Aethos version, are more comfortable.
