On longer rides (with others or solo) what kind of deep wheels do you ride?
I’m contemplating aero wheels for my longer rides (100km+). I’m set on some wheels (45mm), but thinking I could go deeper which would save me some energy here and there.
I’m sorry if this has been asked already: I searched the forum and the internet quite a bit - most topics seem to be focused on racing (usually shorter crits). And triathlon people just go “as deep as possible”. 
Same wheels for everything except gravel events. My everyday wheels are aero 51mm front and 60mm rear (Roval Rapide CLX). These particular wheels were designed for both aerodynamics and stability in crosswinds. Excellent on fast windy descents in the mountains, and the everyday windy conditions here on the flats near the Pacific Ocean. Love 'em.
I ride my Roval Rapide’s (50f/60r) on basically every road ride just cause I gottem so I might as well use em. But if I wasn’t racing at all (or didn’t care about my speed) then I probably wouldn’t bother.
save me some energy here and there
I would be willing to bet that if you did two 4hr rides back to back with decent shallow wheels and then deeper wheels you wouldn’t save any energy. You would likely go a bit faster (and thus farther) with the aero wheels. But I would imagine you would just pedal based on your RPE and your power output would basically be the same.
45mm is already considered a “mid depth” wheel. So depending on the quality of them you are probably already getting like 85% of the benefit of a deeper 60mm wheel. But deep wheels look super cool, so if you think the same and your budget allows for it then go for it. But I doubt you’d notice a difference in your riding going from a 45 to a 60 of similar quality wheels.
lol yes, its mostly about the bling, then stability in the wind, and then marginal gains at high speeds.
I’ll add that if your current wheels are older style, narrow, V-shaped rims then you could notice an improvement in crosswind stability by going to a more modern, wider, U-shaped profile.
I have read and heard many good things about these wheels. Too bad the front wheel exceeds my max clearance. 
You are probably right - that’s what I thought too. But being 20min or so faster is nice too. Especially since those rides have lots of flat kilometers where we transition from one mountain to the next.
I’m thinking about the DT Swiss ERC 1400 which are a bit more “modern” (more internal and external width, they also have this new UV-shape). I could test them for a few weeks and they are really nice. You are probably right here too - it may just be my FOMO.
versus box wheels, if wind tunnel results are taken as max gains, over an hour you should be getting some free speed. And they sound awesome and look great.
I’ve been using 40-something wheels for everything all the time. Road, gravel, and racing both. I don’t see a reason for not just using one set of good wheels anymore.
Years ago you’d have a good set of wheels that you’d save for racing and other spicy rides and alloys for everything else. Nowadays… Buy a good set and get your money out of them ride’em all the time. Enjoy them.
Newest gen wheels with appropriate sized tires should be pretty OK in the wind, but I like a staggered setup just for descending confidence (60/45).
ENVE 5.6’s…every ride, every time. Solo, group ride, race.
Whether you are gonna save any appreciable energy on a group ride by switching to 60mm rims vs. your current 45’s is pretty questionable, though…
I also use Roval Rapide CLX (51mm front and 60mm rear) on every ride, no matter how long or short.
I switch between Parcours Grimpeur carbon (40mm) and Pacenti SL-23 alloy (26mm depth I think). I use the Parcours for longer rides but whilst extra depth feels faster, I would say a little ride comfort is sacrificed, which can get wearing after a few hours, it’s fine but I don’t think I would go any deeper for endurance riding
Yup, road wheels are 51mm. Don’t race on them, just training and group rides.
Gravel wheels are 35mm deep. Race and training.
35-50mm give or take a few is probably the sweet spot for weight, cost, and aero. Run whatever depth within that range tickles your fancy.
50mm for all things road training/racing (albeit not often). 32mm all things gravel.
I’m an outlier here i think. I have a pair of Renolds AR80’s that I ride everywhere. I 'm sure they are faster than my old box sectioin AL wheels. I love the way they look and sound. Deep rims #ftw
I ride 42:65mm just because those were the wheels my bike came with. For my previous bike I bought cheap Chinese 60mms. Carbon aero wheels, even the cheap Chinese ones made riding a lot more fun. I have ridden them upto 8-9 Beaufort that got a little sketchy but below that the 42:65 are just fine. I’m not very heavy either (75kg). The Chinese wheelset was a bit more sketchy in crosswinds though…
Carbon wheels, they look cool, sound cool and just feel fast
68 front and rear, whether training, racing, or coffee riding. 85kg us enough to make that a no-brainer in any wind condition…
I used to ride the first generation of Hadron 625’s (62.5mm deep, carbon fairing and an alloy braking track) and tbh I never found them any worse than the Shallow Hunt Aero Wide when I went Tubeless and moved the 625 front to my TT bike. Prior to the Hunts the 625s did lots of longer rides, including the LBL and the Mallorca 312 and a ride of 100km+ weekly.
Maybe I need deeper wheels than 45mm 
Short answer: yes
Longer answer: I race and train on the same wheels currently, in the past when I’ve swapped it’s been different aero rims. Haven’t owned really shallow rims in a decade
