The Championship CADEX of Kristian Blummenfelt

We have seen this frame before but we haven’t seen it this well put together.

The Frame: CADEX Tri

  • Size Small
  • 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)

Drivetrain: Shimano Dura-Ace Di2 R9200

  • Crankset: Dura-Ace Electronic Di2 shifting 58/44T 165cm
  • Powermeter: Shimano Internal
  • Cassette: 11-34T

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

  • Maurten Gel 160 packs stashed in the integrated top-tube compartment

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. 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.

    What is so ugly?

  3. 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.

    was the bike put on diet as well ?

  8. 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!

  9. This is great agreed.

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

  10. Hahahahaha…

Be honest: do you know how to change a flat on your bike?

If given the choice, you prefer to ride a wheel that is:

Do you believe that hookless wheels are unsafe, or simply not for you?
