I watched that video and it will definitely be a pain in the ass. I think you would have to mix in something else and then pour it into the bottles.
True, but I use a shaker bottle to mix my malto anyway. But youāre right, youād need to bodge something so they stand up before you put them in the cage. I was riding with a mate this morning with the new Madone, he was using a round bottle in the cage so Iād probably just save the aero bottles for race days if I had them.
Just in case anyone has a specific question about the bike and how it compares. I just got the new Gen8 Frame after my Gen6 IsoSpeed was warrantied and would be happy to answer any questions. Have about 300ish Kmās on the bike already.
Itās an interesting test because of course, I brought over my original wheels and drivetrain from my Gen6, so aside from the frame/cockpit nothing else has changed. Iāve also gotten to ride the 2022 Emonda SLR and Madone Gen7 SLR, so I have a few frames (hah) of reference.
So far no reviewer is giving this bike enough credit for how comfortable it is. Thatās not a āsexyā stat. But wow the compliance marketing speak is legit, it rips over rough roads. Over 35kph you can also āfeelā the aero advantage compared to the Emonda, however, thereās nothing in it compared to my Gen6 so far. Splitting hairs there, which we all kinda saw from their presentation anyway.
Overall I think itās a better bike for more people. I get why they went this direction. But miss the full-on aero bike look.
Old Gen6 and friendās Emonda that Iāve ridden a fair amount as well.

Is the bike compatible with the Wahoo Kickr core?
I believe so, but you need the updated axle parts from Wahoo.
Iād assume they all ship with these now, but I had to ask for mine back when I got it. There are certain Trek bikes and maybe a couple of other brands as well that werenāt approved for use with the stock partsā¦ 
So, not quite as aero as the 207w of the bike it claimed to be as fast asā¦
For context some other bikes in that aero range

And somehow with a rider on it. CyclingNews reported the Madone Gen8 as the 2nd fastest in their testing of a very similar group. Sure seems like the frames themselves are incredibly close, within the margin of error sometimes and it comes down to the finishing kit. Wheel/Tire combo, bar widthā¦ect
- Specialized S-Works Tarmac SL8 (~279W)
- Tek Madone SLR 7 Gen 8 (~279W)
- Factor Ostror VAM (~279W)
- Cervelo S5 (~280W)
- Canyon Aeroad CFR (~281W)
- Van Rysel RCR Pro (~282W)
- Giant Propel Advance SL 0 (~282W)
- Scott Foil RC Pro (~283W)
- Cannondale Supersix Evo 4 (~283W)
- Pinerallo Dogma F (~283W)
- Look Blade 795 RS (~286W)
Damn! No wonder the Van Rysel is so cheap! 3 watts LOST!

I think thereās a little too much room for error when they have a person trying to replicate a position on almost a dozen bikes with different geometries and bar sizes. Granted a mannequin would still be tricky to set up identically across the bikes but Iād certainly trust the data more, personally. I like Tourās leg only test since the legs are mostly what interact with the bike anyway, and the trouble with setting up a full body mannequin is whether the position they use is relevant to you. Maybe some people canāt hold that position or have a different physique, but our legs are mostly similar.

Agreed on all of the above. Also went and double checked. The CyclingNews test was done at 40kph instead of 45kph for the tour mag. That likely helps account for the increased difference between the bikes.
I wonder how much data like this reeeeally changes people buying habits? Like if you were a Trek fanboy, would this sway you into buying a Canyon for 10-13w at 45kph? The Canyon in my size also STILL comes with a 42cm wide bar in the CFR trim which is bonkers . Would the Trek with their standard 39cm bars make me faster out of the gate? Probably? Choices choicesā¦
Iām a huge TREK fanboy and would get pretty much anything over the Gen 8. Maybe Iām biased cause I own a Gen 7 though which was pretty broadly agreed to be faster, more comfortable, and didnāt have the t-shirt sizing fit issues. Even if you take TREK at their word on the aero claims those two latter issues with fit and comfort still donāt seem to exist (at least not as widespread) on the SL8 or SSE, and as a bonus they test faster in the Tour test which granted you may not feel.
No the Aeroad comes with adjustable bars that go from 37 to 42 cm. Also with the price difference between the two you could buy like 10 barsā¦ Or those super expensive syncross wheels and make it even fasterā¦
But unless youāre a hardcore racer I donāt think basing your decision on the aerosavings of a frame is really s thing (provided the geometry allows you to be aero on the bike), ride what feels good to you.

I always forget about Canyonās fancy adjustable bar. Thatās slick.
I got lucky being able to try out the Gen8 after a warranty issue with my Gen6. But even if I had all the money to buy any top end road bike right now. I honestly have no idea what it would end up being.
Edit - Ok just saw that new Time Aero bikeā¦ yes please 
I just got a gen 8 sl frame set on warranty to replace my gen 6 sl frame after a few years owning it. Iād requested a gen 7 but apparently they had no frames left and discontinued them totally.
Had chronic isospeed issues with that gen 6. Iād bought the madone slr cockpit as well so they also gave me the aero rsl cockpit to cover that.
Iām grateful they did this but the bike defo doesnāt feel as fast on the straights, although the whole thing shaved pretty much a kilo off the previous bike which is welcome.
The gen 8 is clearly a cost cutting exercise, I do wonder if theyāll reintroduce another aero bike in a couple of years though. Cervelo have their new S5, Van Rysel, Canyon, Ridley and Scott all have their aero bikes, most of which funnily enough weigh less than the gen 8 with the same builds/price points 
The 8 is made in Cambodia as well which I found interesting, the 6 was made in Taiwan, which is where the SLRs are now made I believe.
