  • Integrated hydration and storage

Wheels: CADEX Aero Wheel System

  • Front: CADEX Aero 4-Spoke
  • Rear: CADEX Aero Disc
  • CADEX Aero Tubeless Tires (700x28c, 320 TPI) (Tire Pressure 4 bars)

  • Crankset: Dura-Ace Electronic Di2 shifting 58/44T 165cm
  • Powermeter: Shimano Internal

Cockpit & Hydration

Single Bottle + Straw to Internal Bladder

Home Made Integrated front hydration: bottle positioned between extensions for aero neutrality

Cockpit: Sync ergonomics Aerobar Three in partnership with CADEX.

Rear hydration: TriRig carbon cage mounted to the wove saddle for his second bottle

Birdseye view of how that bottle cage bolts straight to the seat.

Nutrition Storage

Small But Significant Details

  • Ironman, World Triathlon, and Olympic decals on the frame: Great reminders of the results.
  • The Special Edition Wove V8 Saddle

KB’s bike is as clean as I have ever seen it. It looks like he has really taken the time to not only dial in his position, but make sure that the bike is put together perfectly. No rusty bolts or wires hanging out. Everything has a place and it’s super polished.

I say this with the disrespect it sounds like…

That’s so ugly

What is so ugly?

It is so ugly it is slick. I don’t normally like this type of bike but that is pretty good going. Sleek and understated.

Thanks that’s my best work.

was the bike put on diet as well ?

Man…I would’ve 100% agreed with this the first time KB pulled out the Cadex Stationary bike several years ago, but I agree with @SheridanTris …there’s something slick about this matchy matchy b&w set up. @E_DUB did you b&w these photos…or are those red bull bottles grayscale as well??? If so, grab me one!

11

This is great agreed.

But it’s like polishing a turd, after all the work it’s still a turd.

This is a size Medium bike not a Small.

If that style of bike was faster than a regular frame would it not have been proven in the wind tunnel and therefore all manufacturers go down this route?
I’m no engineer but I would assume that the reduction in rigidity from taking out one side of a triangle would require the remaining tube to be significantly strengthened thereby increasing weight.
Not trying to be anti progress - I’d ride whatever is fastest.

Wow! 58/44 with an 11/34 cassette? I’m guessing he doesn’t do a lot of climbing with those gears. And he’s a monster on the power.

44x34 is very similar to 39x30. At a cadence of 75 rpm, it’s ~12 km/h.

Unless there are ramps over 12%, it’s quite achievable even for a top age grouper. I don’t think he plans on climbing under 350W either

Marten Van Riel was talking about using 58t & 11/36.
Seems lots of the front guys are going 1x. Does seem strange on this course.

It’s not like they’ll be going in blind. They would’ve all done their homework (most on the actual course) so they’ll find what works for them.

19

Yeah but it will be a shiny Carlsberg type of turd that has a good possibility of being World Champion!!!

20

56x36 at 75 rpm is ~14.5 km/h.

Pros will ride the 6-7% climbs at 21-23 km/h. Maybe in just a few corners they can miss easier gears to maintain a high cadence.

If I didn’t have to pay for parts, I’d go with their chainrings.
