was able to get the some more data from images i found online.

* disc brakes penalty is minimal *

disc aero bikes

propel advanced sl disc with stock wheels(42f/65r) 209 watts. with zipp 404 disc wheelset 206 Watts !!! weight 7.4kg

specilized venge vias disc with stock wheels(roval clx64) 209 watts. weight 7.5 kg

merida reacto disc team-e with stock wheels(dt swiss prc 65) 210 watts weight 7.5 kg

caliper aero bikes

cervelo s5 with stock wheels (enve ses 4.5) 207 watts. weight 7.1 kg

madone 9.9 H2 with stock wheels(aeolus 5) 208 watts. weight 7 kg. please note aero penalty H1 vs H2 heatube !!


a straight out comparison between Dogma F10 vs F10 disc. the bike had zipp 303 vs zipp 303 disc

Dogma F10 disc 214 watts 7.5 kg
Dogma F10XL 213 watts 7 kg

ability to ride wider tires with superior rolling resistance the 1 watt diff is all but eliminated.

only issue with aero + disc is weight.

the lightest bike was trek emondal slr h2 721 gm as aero as a brick at 238 watts

new swork sl6 delivers on the aero 221 watts but light at 850gm
pinarello f10 is the KING of grand tour bikes class leading aero and great weight 881gm

Thanks for posting this, interesting to see the Merida out performed the Venge!

[spartan]

edit . the reacto disc was 210 watts not 201

[spartan]

the aero data graph is quite revealing. the super exotic zipp 454 nsw is less aero than the 404 fc.

[nemeseri]

So TLDR; caliper brake aero bikes are faster and lighter than disc brake bikes.

What a surprise

[AJS914]

So how do you interpret the 238 watts Emonda vs. the 208 watts Madonne?

Is it like your FTP is 30 watts higher, for example?

[Shrike]

Excellent, been waiting for these! Thanks spartan!

From a quick scan of the images, it looks like the Aeroad was king over a couple of courses?

@AJS. Those wattages will relate to the power needed to maintain a certain speed, usually 40km/h

New Tarmac looks well done, seems to square off nicely against the new R5.

[silvalis]

so... the stock giant slr0 disc wheels on a tcr are considerably lighter and more aero than 404 fcs?

[DutchMountains]

I love how they translate the raw data into the expected gains for a flat/hilly/mountain 100km ride. Does anyone know if they have done this in the past for "anything but aero" bicycles, for example a 10kg steel bike with 32mm tyres?

[mrlobber]

New Tarmac looks well done. Wonder it squares off against the new R5.

Tarmac vs R5 in Tour Test (both rim brake versions)

Frame + headset weight: 897g / 973g (size 56)
Aero 221W / 223W
Headtube stiffness: 105 / 123
Fork stiffness: 65 / 44
Seatpost comfort: 104 / 87 (lower is better)
BB stiffness 76 / 77

Nice! I've just seen another thread where they were saying the Tarmac had a traditional handlebar v the R5's aerobar. Spesh have done some properly good work on that Tarmac

[mrlobber]

I wouldn't call R5's handlebar "aero", although it probably saves a watt or two versus a round bar.

[cyclenutnz]

This is going to be hours of fun for me. Will digitise and reanalyse as Tour are terrible at analysing their data.

Is it like your FTP is 30 watts higher, for example?

the way I see it is that you have to put out 30 watt less to maintain a given speed on the Madone (I don't know what the reference speed is, I believe it is 40 km/h)
