    Disc-specific carbon rims tend to be more shallow?

    I'm noticing that most disc-specific rims are 45mm depth or less. You don't see too many manufacturers making them in 50mm or more.

    Is there a reason for this? Or am I just imagining it?

    I remember looking and seeing HED, Zipp, and Enve, all with deep wheels. I stuck with the Rovals, that came with the bike as I have had no issues but I made sure the options were out there. Particularly, the HED Stinger line.

    Perhaps there are fewer partially due to the perception that discs are less aero so aero is not the objective??

    My completely armwaving speculation is that the initial and primary markets for road discs have been gravel bikes and endurance bikes, bikes that don't have aero as a major selling point. As discs make inroads into other bike types, I'd expect to see deeper rims.

    Next time, consider posting in the Wheels & Tires forum?

    Bingo. Demand.

    Since roadies are holdouts and digging their heels in to disc brakes....doesn't make sense for economies-of-scale rim makers to sink a ton of money into deeper-section rims for disc.

    Yup. I have Enve 5.6 disc (F-54mm/R-63mm) wheels on my bike and they make a 7.8 (70/78mm) disc wheel too. I had also looked at options from Zipp, Reynolds, and a couple of other manufacturers. They're available

    If I was to take a guess at why disc rims tend to be shallower is because of the state of disc bikes right now. Most disc bikes right now are more endurance rather than race focused because of current UCI rules. >50mm rims tend to be better daily drivers than deeper counterparts which are usually better for racing and TTs.
