It's interesting the amount of pushback this thread is receiving, almost like people don't want to admit that the gear doesn't make as much of a difference as the rider does.
So the group was having a really good day yesterday, which helped me set some PRs. Well, except for the finishing sprint, which I won, guess everyone was blown up by then after helping me ride so fast.

I did like your title though. For the most part and to a large extent it is the engine.
I don't think your PR's are so much about the type of bike as they are about how those two bikes fit you, are equipped with the proper gearing and yes even the proper tires for the route you ride. I wouldn't use a TT bike for a typical group ride. IMO a gravel bike is not much different than a road bike. Mostly just allowances for bigger tires. Between TT bike and the gravel bike, I'd expect the gravel bike is more appropriately geared for the route you ride.
But since I don't know what they actually are, those statements are just supposition on my part. You'll need to fill in the blanks.

True, and it felt pretty good. Only the second sprint zone I've won so far. But I also like to do a lot of pulling, so I'm usually pretty beat when everyone takes off.
Always. Everyone at work asked me if I got rid of my blue bike (I bring my bike into the office when I'm riding after work), and I said nope, there is no getting rid of them, just getting more! lol

Well it's conversation. You just never know where it's going to go once you voice it to the masses. You as the OP should certainly steer it to stay in line with what you are expecting. But don't be surprised if more are interested in the side conversation.

While I use the aero bike for TTs, it's not a true TT bike, it's a Fuji Transonic aero road bike. I've just put deeper wheels and clip-on aero bars for my club's TT series. At some point, I'll probably pick up a dedicated TT bike, but I'd also like to stay married, so that'll probably have to wait until next year lol
I'd have to agree, even looking at my Revolt, it looks like a pretty typical road bike, until you notice how much clearance the fork and chainstays have. Stack is only 26mm taller than my Fuji, so it's just a bit more relaxed. With the 28mm road tires, it's really just a comfortable endurance geo road bike.
I love the Thursday night Airport Ride, but I usually can't make it due to shuttle duty for kids' soccer practice. But one night I was finally able to make it and took off on the intermediate sprint and won it with clean wheels. Then a buddy rode up and said, "Good job. The thing is, we don't sprint that sign anymore."
D'oh!
D'oh!
I do a fast group ride with my LBS, and haven't quite learned the sprint zones yet, nothing is announced or marked, they just know when to go. Some strong guys in that group too, which is good, helps me push myself.

PRs in group rides? The group speed has far more to do with our speed than our effort. Example: a race I rode twice. Second time would have ticked every PR. 26.6 mph for 105 hilly miles. All I did was ride near the front, make the split with 15 miles to go and not get dropped over those final miles. Yes, the hardest thing I've ever done. But a finisher the year before finishing 10 minutes slower would have soloed the last 15 miles and won by 10 minutes. Both races, over 100 riders. Second race, 3 hours, 56 minutes and change. All 30 of the remains of the field finished under ~3:58. First race, 4:19 in pouring rain. Field sprint. Now the second race set the course record. Old record was a minute or two slower. John Howard - who went away with John Allis with 50 miles to go!
Now, if the OP was driving the pace most of the ride, OK, the PRs are relevant.

I think people are getting hung up on the group ride thing that you got an advantage over a solo ride. But I think your larger point is true about the engine. I recently did a road race with an entry level 2018 Allez, so it's about 22lbs. I finished in the upper half of the field, 90sec behind the winner, but any lack of contention was due to my own fitness and likely not any equipment limitations. If I had been doing anything other than sweet spot training, I might have had the extra physiological gear needed to be in contention. But, I was curious about upgrading my wheels from the stock box section ones, and I'm honestly not convinced any upgrade will really give me an appreciable difference. When I ride solo, I don't care about speed for a few tenths of mph difference, and when I'm in a group other factors come into play. I've posted this under a couple of wheel related topics and it hasn't triggered any responses.

A gravel bike on GP5000's is likely about as fast a setup, given what was pictured, than some folk's older road bikes on pretty generic road tires and box rims. Not everyone on an A ride is on a Venge/Propel/Timemachine with deep dish wheels and aero/race geometry and fit.
In fact, those tires on CRR alone could be up to 10w+ per tire faster than another road tire. So 20w faster.
If you came in saying you went off the front, solo, for a 1/2 hour before getting caught on the gravel bike and were rocking 32mm+ gravel grinder tires at a minus 10 to 15w penalty per tire then I'd have been more impressed.
I've brought the CX bike to the A ride before thinking it was gravel night. Oops. Did just fine, could break away when the road grade went positive just fine. The 1x was annoying trying to go downhill.
If you want to prove it's really the engine, try it again on your gravel tires and try to stay at least a 1/4 mile off the front solo for at least 1/2 hour or so. Not cheating a stop light or some crap either.
If you can........then you're at the wrong group ride.
Everybody knows that a mixed surface geometry drop bar bike with road tires does the job 99% as well as a dedicated road machine does. That's not a revelation.

So between the two bikes, is there significant gearing differences? Or do you think your performance difference was more from the tires or how your sit on the two bikes?

If the bike is 4lb heavier, and any of these strava PR's are hills, then you would have been even faster on your lighter bike. Not sure what the point is here, you had a good ride, maybe the group was faster, maybe you had a tailwind, maybe you ate your Wheaties today, it doesn't matter. If you rode a 4 lb lighter bike, and did the same course under the same conditions, your times would have been faster. Unless of course your bikes are not set up the same or the position is not optimized, etc. etc. But, all other things being equal, a 4-lb lighter bike will be faster, especially going uphill.

Transonic has 52/36 and 11/28, the Revolt has 48/32 and 11/34. I spin out at about 35mph on the gravel bike, but that wasn't really an issue, the extra gearing may have helped on a couple of the climbs tho. In truth, I would say my performance was probably about the same overall, guess I was just surprised that the gravel bike wasn't much different from the aero bike. The extra comfort definitely helped on some of the rougher sections.

I tend to think this way. In a large ride that is moving quickly, my wattage is pretty low and easily sustained. I am not working hard, the guys at the front are.

Could you tell you were faster during the ride? That's always fun, when you feel faster, then you check the numbers afterwards, and you were.

In fact, I think if you're a rider on a group ride who constantly drops the group somehow when on your roadie/race bike.......start bringing the slack geometry slow tire bike for a better workout and maybe better tactics. You ride differently when you're able to just attack and disappear versus having to in-fight and conserve/burn.
It's fun once or twice to drop the group up all the hills, but after a while you're just doing intervals alone. It's more fun being "in the mix".
It sounds like a "flex", but it's a valid point to intentionally handicap yourself on a group ride to make it interesting. Nobody is winning anything. Strava PR's or KOMs don't win races or get you a PR in a time trial.

I've often heard people say that it's the engine, not the bike. Last night was a good example.
I took my gravel bike to the A group ride, because my aero bike is setup for a TT on Thursday and I didn't want to mess with it. So I put on my road wheelset with 28mm GP5Ks (measure at 30mm) and ended up setting nine segment PRs, riding my non-aero, 4lbs heavier, endurance geometry gravel bike.
I think part of it is the whole "comfort = speed" thing. Some of the roads we were on are pretty crappy, on a road bike you have to be careful and you get a lil beat up in some sections. On the gravel bike with bigger tires and compliance built-in to the seatpost and bars, I was very comfortable and had no problem pushing through the rough sections.
Yes, in a lab, aero trumps all, but in the real world, sometimes it's a lil different. That being said, I'm still riding my aero bike with 88mm wheels and clip-on aero bars for the TT.

Are you riding in St Paul, MN? 'cause that's exactly my experience on the rough roads around St Paul (I've been on washboard gravel roads that's easier to ride than St Paul's paved roads. ). I took the heavy gravel bike for a group ride while waiting for part for the road bike, the "slow" gravel bike isn't the big penalty you'd expected (based on marketing hype). I'm not the strongest rider with our group but I ended up riding off the front and having to back off. The result for me, I'm riding much lower tire pressure on my road bike for the St Paul group rides and getting more PRs.

In the constellation of bad roads in the Twin Cities metro, Saint Paul gets special mention for being abysmal this year. It's truly hazardous. Patching from the rough winter has helped quite a bit in many spots around town. Except in St. Paul.

On the geometry tangent: What is the wheel base of the two bikes? Chainstay length? Head tube angle?
I've been of the mind that longer chainstays help with tracking a straighter line at the expense of a "feeling" of responsiveness. I have 2 bikes both with 20 inch (50cm) chainstays by design. I find they easily & deceptivly ride 18-22 mph on the flat/level but "feel" around 14 or 15mph.
Also the relaxed head tube angle may kick your front wheel further ahead (by comparison) making for a longer more stable bike that so you again, ride a straighter line. Also rough surfaces (which you say you ride on) is less likely to knock you to a new direction. Slacker HTA results in a bike that "rails" corners better (meaning at the expense of easy mid-corner corrections)...All this, of course, dependent on appropriate rake & trail being smartly chosen.
I ask because if your gravel bike does indeed have longer chainstays & slacker headtube than your aero bike it may help to explain your surprise. In short: In your particular situation, your gravel bike cutting through terrain may mean more than your aerobike cutting through the air.
I'm sure someone here will pipe in to educate me on my "wrongthink" but in anycase, for whatever reason, it sounds like you have a nearly optimal ride for conditions.
Rock on!

Hah. I sometimes ride the TCBC "Gears Tears and Fears" hill climbing ride on Tuesday nights. I'm sure it's the same hills and the same road hazards.

Depends on which helmet and wheels you started with. That's particularly so for helmets, which tend to be much more individualized. That said, for most riders, in most common sizes, clothing matters roughly about as much as a helmet, and handlebars matter roughly about as much as wheels.
