I’m going to have around $1500 US to drop on a new rear disc wheel. It will be going on a Ventum Tempus with SRAM Force 2x, and 28mm GP5000 TT TR tires. Currently, I’m leaning towards the newest version of the Cadence TT Disc (22.5 internal, 32.8 external), but I’m also looking at the Parcours Disc (22.5 internal, 30.5 external) and the Scribe Tempus (21 internal, 29 external). All have hooked rims, so I could easily run high 70s PSI. All three also have pairable fronts that are 80mm+ deep.
Thoughts? Am I missing something that I should be looking at?
There have been a couple pretty detailed/lengthy ongoing threads that’ll probably get you pointed in the right direction. This being one of them: search “disk” too…
Numerous posts here by people who are professional aero testers and have done real world testing at the highest levels talk about how good these wheels are
I have ZERO connection to the company except as a paid customer
I think they’re coming out with updated wheels sometime this year. There was a thread where it was all discussed, possibly the other Disc wheel that was linked above.
Match the disc to the tire width you want to run, and like you said get a hooked wheel, not hookless for optimal crr (and safety).
After that the best and worst discs are ~ or <3w apart. Given that the most accurate wind tunnel is ~ .75w standard error a 1-2w difference between wheels isn’t something to worry about unless you’re in the Olympics.
Certainly less post-tariffs. I picked up my D8 Nxt Disc for $1151 but that was pre-tariffs. Looks like list price is now $1599 before any discount codes (but including tariff). Still seems like one of the better bang-for-the-buck options. Only other disc I would consider would be the Scope Artech Disc but the difference between the two is not worth the $3,298 list price for Artech IMHO.
I would highly recommend looking at the HED Disc wheels. They’re a very reasonable price point, bomb proof, companies been around since the 1980’s, and some of the fastest times have been ridden on them in current and past decades. I have a Jet Disc and Jet 60 that have stayed true and spin amazing after 15 years of riding on them. I splurged and bought a Jet Vanquish Pro last year for my 50th birthday, and I really can’t tell a difference between that disc and my 15 year old Jet Disc.
*** Always boggled my mind that Slowtwitchers praised FLO wheels that were heavier, more expensive and outsourced from China! With only final inspection done in the states vs. a made in the USA Steve and Anne Hed wheel. And HED’s customer service for issues and answering technical questions is top notch!
HED uses hookless rims so it should not be considered by the OP nor anyone who wants to run at least 70 PSI.
FLO on the other hand has hooked rims, and their wheels are super reliable and fast. If they were still selling new wheels I’d recommend them to the OP.
HED absolutely does not produce hookless road rims. Its all I use road and gravel. I won the 12 hour world tt champs this year on the Vanquish rear. I also run a full Lincoln (hooked) disk for gravel
Not to repeat the entire 2025 best disc wheel thread, but HED ‘hooked’ (or rather not hookless) are rated to max pressures of 70psi for 28 tyres, and 75 max if you’re running 25mm. As you can see from their charts then below 180lbs/82kg then they advise lower pressures anyway, bt if you weigh more then you can see even by their charts then the rim is the limiter. Despite many attempts the collective efforts and wisdom of Slowtwitch disc wheel thread participants never got to the bottom of why they rate them to the same limits as hookless.
And I guess the relevance is that if someone isn’t wanting hookless there’s a good chance that the reasoning for that is related to the pressure limitations of that technology, which is shared with HED hooked rims.
Knowing HED and their general philosophy, I believe it’s a very conservative pressure rating. But that’s a discussion for another thread.
Their Vanquish Disc does use the newer V62 rim profile, making it one of the wider options on the market. Ideally suited for 28’s, but 30’s fit just fine depending on your frame clearance (and knowing aerodynamics of the rear tire don’t matter as much as the front).
Massive downside of HED is that you do not get the desired (and only true reason to run a disc) woosh woosh sound. HEDs are just a spoked wheel with side walls. Fast yes! Heavy… also yes
