Interessant, ich hätte nicht gedacht, dass der Unterschied so gering ist zwischen TT Maschine und Rennrad. Ich kenne die Strecke nicht, aber wenn die Abfahrt technisch anspruchsvoll ist, kannst du da mit dem Rennrad auf gesperrter Straße sicher noch ein bisschen was gutmachen.

[@stefan78able]

Very good video, I did ride the course 6weeks ago and leaning now towards using my Road bike this September. The climbing is a bit more comfortable and the control much better down the technical descents. I don't think you do re gain much time over the 20k flat section if using a tt bike. Well, I better get used to my Road bike then.....🚴‍♂️💨

[@karstenmeinders4844]

Too many variables changed from day 1 to day 2:- bike type- suit type- helmet type- bottle position- active cooling vs. sweating- knowledge of the courseOnly one parameter did not change: testing in public traffic with all hazards and impediments to bikers.An age group member of my tri club will use his road bike. So will S. Kienle as he announced in his YT channel.The tip of Roy to bike this course as often as possible is hardly feasible for most participants (except the locals).

[@deNudge]

5 watts gained is perhaps even less than putting the bottles behind the seat (I saw your aero video and you talked about 11 watts for the bottles alone). So you would be in clear advantage using a light road bike set up correctly here.

[@tomnix8194]

Even you could use the disc on a road bike

[@fiddleronthebike]

@@tomnix8194 I think a disc doesn't give any advantage on this course

[@RoyHinnendotcom]

and Gustav Eden won on a RoadBike - it is what i proposed!

[@kubinho6]

So the triathlon/TT bike was faster, and also 5W less power needed to be faster... Yet the recommendation was to use Road bike (??) Imagine this conclusion comes more from "comfort" or perception of climbing factors, but numbers tell a different story... Or did I not interpret the test correctly? Thanks for putting this together by the way! Very helpful... My main takeaway here is that you got 2 flats in 2 rides... CRAZY! I will def re-think my choice of tires based on this :)

[@RoyHinnendotcom]

Hey Ricardo, the wattage come from Garmin, so i am a bit carefull there, also Adrian rode a bit more agressive with the aerobike because i know the course better, i will credit him about 45-60s for this, conclusion comes from less weight, more agressive breaking and cornering - but if you know the course well you will be faster... whish you a great race...

[@eikemueller4242]

Please note: emptying 2 bottles produce the main part of the reduced weight (87kg down to 82.8kg)

[@RoyHinnendotcom]

The liquid went from the Bottles into his body, from there it was used up for his performance...

[@fiddleronthebike]

1.5 kg is not the main part of 4.2 kg - and then what goes from the bottle into the body does not change the overall weight

[@franzkohlack8336]

Hallo Roy, ich denke auch, dass das Rennrad hier bergab mit gesperrter Strecke noch viel gut machen kann.

[@andrewmchowell]

I’m 61kg. I have an emonda SLR approximately 7kg and a speed concept approximately 8.6kgs. Above average handling skills. Would you still recommend road bike?

[@RoyHinnendotcom]

Yes I would and I would ride the SLR from now on until the race, place your Bottles behind your back, ride save tires with milk.

[@lotharofficial]

Great Video! Thank yo so much Roy for doing this!

[@tengamangapiu]

For such a technical course, what about using my Cervélo P2 (2017) which comes with Di2 shifting, but modifying the handle bar to that of a road bike and also the seat angle a little bit further back, to go towards that 74 or 73 angle ? With Di2 I could shift from both the road bar STI shifters as well as the clip ons.

[@nathalielaurendeau8450]

Hi Roy
Would u know what type of clip on Tri bar I can put on my R5 disc Cervelo road bike ? Bars are odd shape ?
TIA
Great video btw !

[@RoyHinnendotcom]

Syncros or Syntace will work... Good Luck

[@robertinchch]

Hi Roy, I've notice on the data extraction it shows 1220m and 1224m gain versus the 1367m mentioned on the race map.. that's 143m difference which is quite a lot considering. Any thoughts on that?
Cheers
Robert

[@RoyHinnendotcom]

yes, its more like 1224m gain! we were also surprised of the difference!

[@YourPetNutritionist]

What do you mean by "putting the milk" inside the tires?

[@seulebrg]

I am assuming they refer to putting sealant (typically white colored) into tubeless tires. The sealent, as the word would suggest seals the small holes in the tubeless tires during a ride, thereby reducing the likelihood to get punctures.

[@RoyHinnendotcom]

is for sealing a cut of the tire! you put it in before you race...

[@jesusclemente7976]

Do you know where I can buy hand plugs for a flat carbon handbar like in this video? thanks in advance

[@RoyHinnendotcom]

What are you looking for, sorry?

[@jesusclemente7976]

@@RoyHinnendotcom apologies. I didnt explain myself clearly. I am looking for the handbars you you show in the first bike to be more aero. I notice that is for flat handlebar like mine. All the handbars I saw in the market are for round handlebars bikes. If you could tell me where I can buy that one or one similar, I would appreciate it

[@mrgizmo7975]

It's not a bike vs bike comparison. You are changing a lot of variables at once.

[@peaknut1]

Great video

[@keule719]

Hi Roy, super Video. Was würdest du über die Strecke in Rapperswil sagen? Ich denke da fährt man mit nem Roadbike besser oder ?

[@RoyHinnendotcom]

Rappi ist eine Aerostrecke zu 100%, die Höhenmeter viel einfacher zu fahren als in Nizza, Höhenmeter ist nicht gleich Höhenmeter.

[@Ton7o]

What about gearing???

[@RoyHinnendotcom]

If Froome needs a 32 to win the TdF - we also need a 32.

[@alexanderrieckmann6255]

Interessantes Video lieber Roy! Welche Clip-on Aerobars sind das an dem Scott Bike?

[@RoyHinnendotcom]

Hmmm, ich frage Adrian... wait...

[@RoyHinnendotcom]

Syncros mit Original Scott parts...

[@alexanderrieckmann6255]

Danke für die Antwort! 😄

[@Bigjuergo]

next time do the test at 5am in the morning without traffic

[@EmanBoom]

What size cassette did you use on the bikes?

[@RoyHinnendotcom]

11-32

[@YourPetNutritionist]

Will I be okay to ride my Cervelo P5?

[@RoyHinnendotcom]

P5 - hmmm - whats the weight of the whole Bike? Whats your weight?

[@YourPetNutritionist]

@@RoyHinnendotcom I have no idea!

[@RoyHinnendotcom]

@@YourPetNutritionist than i can not answer - sorry

[@tomnix8194]

If you have no idea about the weight of your competition bike I am quite sure that the margins of changing something are so small that in every case is the best way to keep it like it is.... Good luck for finishing!

[@muckemann]

frage vielleicht noch: scheibe ja oder egal.

[@RoyHinnendotcom]

Muss ne sehr leichte Scheibe sein, Lightweight?

[@muckemann]

hätte die citec mit 1kg. is wohl auch leicht genug im gegensatz zu manch hinterrad

[@meder303]

👍🏻

[@Hubertus-ko6yl]

Klar! - Bei 30km/h brauchst wirklich kein Aero-bike. Zudem scheint der Athlet für seine Sportart und Leistungsvermögen und diese Strecke eher schwer zu sein. Sorry...

[@Xmasx123]

Wer bestimmt, was zu schwer ist?
