Bikes of Kona 2024: Jackson Laundry’s Ventum Tempus
Frame: Ten years after the release of the original Ventum One, Ventum is back with the all-new Ventum Tempus, expected to launch in early spring 2025. Ventum has opted for a more traditional double-diamond design, which is now UCI-compliant. In addition to the liberal use of 6:1 airfoil sections, the extra-wide fork and seat stays will catch your attention. We’ve seen more of this trend in recent years as manufacturers work to direct airflow around the wheels.
Weight was also a key design input for the Tempus, which is expected to come in at a fighting weight of less than 20 lbs.
Saddle: Jackson is perched upon a BiSaddle Hurricane Pro 3D set at a very unusual -17 deg angle.
Cockpit: Ventum partnered with Profile Design to create the yet-to-be-released, non-proprietary Wing Ultimate front end for the new Tempus. However, Jackson replaced the Profile extensions and cups with a FastTT cockpit. He also applied some homegrown engineering to elevate and brace the front end, ensuring it met his desired fit coordinates.
Jackson uses skateboard tape for a bit of extra grip on the extensions without adding bulk. And, this Garmin Edge 130 Plus takes up minimal space and tucks nicely between the extensions.
Hydration: We are seeing more and more use of 3D printing to create customized solutions in order to store nutrition in the most aerodynamic efficient way. Jackson has cobbled together a system that holds 3 different bottles using the tried-and-true Xlab hydration products.
Drivetrain: SRAM Red with a 56/43 front chainring and a 10-33 rear cassette. Jackson uses a Quarq power meter with 160mm crank arms and clips into Shimano pedals.
Frame: Here, you can see the Tempus’s 6:1 airfoil aspect ratio, along with the extra wide fork and seat stays.
Wheels & Tires: Jackson rolls on a set of Enve SES 6.7 wheels along with the fast and reliable Continental Grand Prix 5000 TT TR in a 28mm width.

Digging these Bikes of Kona write ups!! Keep them coming.
I’ll just point out that doing this sort of thing to your bars is not approved by Profile Design.
Damn, how can you be allowed to ride such sketchy front ends…
It is seriously preventing me from buying a new top end bike, you pay north of 10K$ then none of the pros uses them as provided, they have either custom carbon stuff that cost thousands of additional $, or try to mimic it with custom drilled-aluminum/3d printed fairings, that are not only supposed to be forbidden but are only holding by the will of the triathlon gods.
I’d be very pissed at myself and at my sponsored athletes if my brand was to be represented like this to the public.
Can anyone explain what he’s done to his cockpit? Why it would be sketchy as an above poster wrote? Thanks!
Kinda reminds me of the old BMC - which is no bad thing.
Minor typo: this is not a “10-23” cassette.
Maybe a 10-32?
With a inner ring of 43 that caters for headwinds up to Hawi.
Ditlev on 64/30.
Possibly this? Aeria Ultimate Recall – Profile Design
It’s almost a race to who will have the weirdest looking fit.
Let’s be honest. Jackson Laundry is not a highly paid sponsored rider with a team of factory engineers to produce custom made aero hardware to accommodate his desired position. He is more like the rest of us who purchase ready made pieces and then adapts them to his bike. Jackson may not have the cleanest or slickest aero setup, but if it works for him, who are we to criticize. Besides, he is racing Pro in Kona and we are sitting at our computers comparing aerobars.
I’m not criticizing him at all, but the fact that all pros have to find ways to increase reach, angles, etc on bikes that cost already between 10K to 15K for AG.
Bike manufacturers obviously missed something if people still have to screw around with ducktape and handsawed bolts to get the fit they need.
Too bad Matt didn’t put his fit coordinates in the article. He did for Sam’s Cadex.
I think the reach of the Ventum is one of the things people are most interested to know about that bike.
This isn’t targeted at PD or Ventum but why can’t bike mfg’s and bike component mfg’s just make stock parts that work right out of the box? They should have a wide range of tilt, toe in/out, fore/aft, narrow/wide, and extension rotation adjustability. I doubt there will any pro in the field this weekend that is running a stock front end. What does that say about about the current state of front ends? I admit the front end aftermarket is like the wild west out there but bike mfg’s have given athletes no choice as they have produced sub par options for their bike (eg; Trek).
I’ve already spent more than $2k on aftermarket front end options for my Trek SC and I’m still not completely satisfied.
BRILLIANT!!!
But, can he do a kick-flip?
It’s ok; neither can I LOL
This is a pretty established hack in the cycling time trial ranks - BUT really for events that are are 10-40k and take 45min or less. I’m not sure its really the best application for extremely long events, wet hands and a continuous vibration.
