Why are tubular wheels so narrow?

Notices
Road Cycling 的t is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

The funny bit is that aero rims help the pros in a road race in sprints and breakaways but riding in the peloton the wheel aerodynamics do very little. If you do most of your riding without a peloton dragging you along, you are getting a benefit the whole time.
​​​​​​
Helps when I get dropped from the first group in gran fondos and have to take turns at the front of some ad hoc group of stragglers 😒

​​​​​Anyway, I just don't see much of a downside to running a mid depth - let's say 45mm - CF wheel with 25mm tubeless tires. No issues in wind and plenty comfortable at reasonable pressures (that said, infrastructure is not a dirty word around here, and I keep at a reasonable cyclist weight).

Josh Poertner has spoken often about how much energy aero wheels save sitting in a peloton and how significant that can be at the end of a race.

You don't have to be into TTs; you just need to be into solo riding and maximising efficiency. My 1080g (330g rims) 49mm tubs make my bike go like an absolute weapon.

Modern bulging profile, iirc 24-25mm, 23/25 Corsas. Light & aero FTW.

Every time I jump on my bike, I'm stoked I spent over $2k on wheels and tyres.

At this point I don't understand why recreational cyclists bother with tubular.

They don't, and they also don't bother with which tire is fastest- they're out there pushing 30mm watt-hogs.

I actually have friends (ex-racers) who still ride tubs. But, generally I agree with your point. One of them just bought a Rose bike and I think I have him convinced that he needs to go tubeless.

I'm a recreational cyclist, and I rock tubulars because I love riding the best bike I can build.

If I had a sponsor / personal mechanic / unlimited tire-budget I would, for sure, ride tubulars. I used to ride them and repair them (huge PITA!) exclusively in the late 80's.. back when every single beverage was sold in a glass bottle or can no plastic, flats were even more common then. Nothing feels quite like a nice tubular set-up. I borrowed a buddy's bike a few years ago and it reminded me..

Wired-on tires rely on the sidewall to hold the tire in place. A wide wired-on tire on a narrow rim puts more stress on the sidewall than the same tire on a wider rim. Tubular wheels to not rely on the sidewalls for tire retention and are not subject to this concern.

Lots of good and bad info in this thread. Back in the day I used to ride those skinny tubs. Resisted clinchers for the longest of time. Now that I am no longer competitive I ride 28mm (who would have thunk) tubeless. There are still very good uses for tubs, in addition to nostalgia, but they are getting fewer.
