Taylor Knibb's Custom Trek Speed Concept Project One

…and given the influence of social media, I certainly would not discount the use of deliberate disinformation! :rofl:

I, like many, really like the after-the-fact bike pictures and info, but pretty please, try and include front tire size and type (or a close-up pic of the valve stem) for all of them.

Road helmet…

Whoever muted this needs to answer for their crimes with 100 burpees immediately after breakfast at Lava Java straight into a 2.4 mile swim and then straight into 100 burpees.

In speaking with Taylor.. she basically wanted you all to know that she doesn’t like the other tires.. and the road air helmet tested faster….

She’s very thoughtful about her choices.

I will say I love how wound up the sickos (with respect) get on here over some media photos.

Oh I hope she has a aero test video after the weekend , keep people busy for months .

It’s tough to be so concerned about what a pro athlete does isn’t it..

Foley wore a road helmet last year and did pretty solid for ~111 miles. He’s said repeatedly that he will take comfort over a couple watts.

Anyone else notice the Trek photos are from two shoots? One with her setup and one without pedals and the stock Trek bars.

Huh?

Watching the PTN live show now and Kyle Glass claims she found 30 (!) watts.

I don’t mind the 0:00 thing! But I have noticed we have lost the ability to get something scribed on the bike in project one

She did the first test on the hoods . Second test aero . So it’s not a lie.

Small difference, but I’m not sure how that math works out. The formula is RR (Watts) = CRR * speed (m/s) * load (N) (from BRRs website) and hence should, for tires with coefficients of 0,00291 and 0,00249 respectively, be in the ballpark of 3-3.2w for the system (assuming system weight of 65-69 kgs, speed of 40km/h). Right?

You are correct

I would say knibbs system weight is more like 70 to 75 kg
And she likely will go a tad faster than 40 kmh

So if we go with 75kg at a 4h20 split, we are at

75 x 9.81 x (.00291-.00249) x 41.53 / 3.6

~ 3.6w ?

I am bored waiting for the race to start :rofl:

Using this An interactive model-based calculator of cycling power vs. speed , 3,6W would mean about ~1m30s difference over the distance at that speed (given som napkin guesses of CdA etc etc.) Now it might be somewhat less than a minute, or maybe over two, with all the unknowns here, but timewise more than I thought with a power difference that sounds smallish to my untrained ear.

I’m also a bit understimulated waiting for the race to start. :slightly_smiling_face:

she is unlikely to ride 4.20
I would say more like 4.25 to 4.28 …
But still we are talking about 1.5 percent more watts she has to push to go the same speed.
At least she is not hookless lol
