My simplistic hypothesis, be right or wrong, is that the scarab bag is in the path of what is already disturbed air, the banana bags when bulging / fully-loaded are widening the riders profile into what was previously undisturbed air. Also, I like that this approach of scarab bag with aero bags behind it, is modular. I can ditch the Scarab on all but the longest rides. For example, I’m doing a 600k this weekend. The first 400k is flat and fast riding. The final 200k is hilly and going to be at night. So, since the 400k ends where it started, my plan is to roll during the day with only the aero sidebags and then add the scarab before the final 200k. Why the scarab on the final 200k you ask? Well the temp should drop into an iffy layer-up range and I also may need to crash for an hour or two, so I’m packing layers, an ultralight sleeping pad, insulated sleeping bag liner, and an emergency bag. If I were running w the banana bags I would need to have all this on me the whole way which seems like a lot to haul when there’s really no need until the final 1/3. Just one example of how modularity is a big plus for me. But is it really more or less aero when using everything….who knows!Interesting comparing drag for the Scarab bag and aero/side pods. I'd have thought that the Scarab bag produces the most drag. The reason you have the cut away in the frame behind the front wheel is to minimise the turbulent air coming off of the front wheel - that gap you want as tight as possible. Much the same way that you have the seat tube on a Cannondale SystemSix follow the rear wheel. And this bike is regarded as one of the best aero DF bikes on the market that is not a TT bike.
For sure I'd agree that the aero/side bags are bulkier but for me they sit behind the rider in the wake of the riders chest/shoulders. Whilst the Scarab sits just behind the frame cut away where the front wheel meets the frame.
Nice! After installing mine, I do think the 3Ls are probably the better option if you want to keep your CdA tax (did I just coin a new phrase?!) at undermount-bottle levels.Looks like you have quite a bit of storage space now with an acceptable amount of drag for credit card or light touring. The other day I found waterproof Vaude frame bags in 3L and 4.5L that look like they will do the job.

Looks great.I don't like the banana racers because they protrude so far out from the sides of the cruzbike that it seems like they'd cause unnecessary drag. Since I already have a Scarab bag attached, I figure the solution you posted here would work well for me as they'd sit just behind the scarab bag - hopefully not causing much to any additional drag. So, I bought a cheap (Rock Bros off amazon) version. Each giving me 3L. The Rock Bros bag has zippers on both sides so i was able to orient them exactly symetrically opposite to eachother (w/ the caveat being the left sided bag needed to have the inside divider slit open the length of the zipper since the left sided pocket is tiny/unusuable. I thought this was a better solution than hanging the left one backwards - and so long as I don't store anything too heavy in the left bag, shouldn't be a structural issue.
Yeah, Vaude. If I want to support my locals I would buy these. Vaude's headquarters are only 16 km from my home.Looks like you have quite a bit of storage space now with an acceptable amount of drag for credit card or light touring.

I used Velcro AND drilled 2 more holes in the seat to attach via bolt/wingnut. I’m glad I did the latter because while the Velcro seemed to be working well, about 250miles into my 600k yesterday, I hit a bump and one of my bags fell off. So, I attached the bolts for the rest of the ride. Worked great.Looks great.
3L are too small for me and Rockbros 4L has a bad shape for our purpose.
But together with your Scarab and Brain Bag you already have a lot of space.
How did you attach the bags?
Do you have a photo straight from the site?
My idea was to attach narrow carbon plates between the frame and the seat, which I put through the loops on the pockets instead of the velcro straps.
Yeah, Vaude. If I want to support my locals I would buy these. Vaude's headquarters are only 16 km from my home.
I've made some progress on the bags that come into question.
If you are looking for zippers on both sides and freely positionable and removable velcro straps in the 5 liter class, there are not that many bags left.
In addition to the already mentioned Geosmina and Blackburn, I also discovered the Bontrager Adventure Boss.
They are available in many sizes (1.3, 1.7, 2.5, 3.0, 5.0 and 5.9 liters). These are also prepared for attachment with screws and I could easily attach them with 2 or 3 additional holes in the carbon seat.
A local dealer even had the 3L and 5.9L and I was able to hold them to my bike.
They only loosely attached and would end up hanging about 2 cm closer to the seat.

(These are not yet mine! :- )
The 3L looks very nice, the 5.9L is very bulbous at the front.
I think the shape of the 5L bag is somewhere in between, if you can trust the pictures on the website:

And where I already started with the cropping of images, I continued straight away and did some Photoshopping.
Bontrager 5.0 L could look like this:

And my current preference, Geosmina Gravel 5L:

And attached the other way around:

Geosmina also has the "MTB series", which fits better at the front but doesn't look that great at the back:

And the Blackburn probably looks too square for me:

I think I'll go for either Bontrager 5l or Geosmina Gravel.
Congrats on your 23:28 600K the other day. Impressive.I used Velcro AND drilled 2 more holes in the seat to attach via bolt/wingnut.

Hi, guys, sorry for being absent so long!
I will go to PBP as well, but this time I'm going to do it on my Trek Domane. Not because it's a better option. It isn't. If I was trying to see how fast I could do the event, I'm not aware of a better choice than a Vendetta. Actually, a velomobile is probably a little faster overall, but there are lots of small hills on PBP! No, I'm taking the Domane because I will be riding along with a friend, plus an upright is easier to bring on a plane.
I've completed the qualifier season on the Domane, but last weekend I also did an epic 1000 km ride on the Vendetta, with 11.000 meters of elevation, about the same as PBP. The climbs were up to 10% in gradient, and my 11-42T cassette was just right. I use it with an MTB derailleur and a Jtek Shiftmate. Search the forum for pictures. After struggling with saddle sores and the fatigue that comes with upright bikes, it was really refreshing to ride the Vendetta again. I'm usually a wreck the day after a long ride, but today I feel pretty much completely fine. I should add that I suffered from back discomfort this time, which hasn't really been a problem before. Maybe it's an age thing, I don't know.
Strava activity
A dynamo powered lamp is highly recommended, because the summer nights in France are long and very, very dark. (And cold. I'm from Norway, and I was surprised. I think 90% of the Indians DNF'd, many, if not most, because of the cold nights.) But a good battery strategy will work too. A battery bank as well as a small charger is also good for charging bike computer and phone. A really small battery bank can simply be wrapped around the handlebar or boom while you need to charge on the go.
When it comes to bags, I prefer the Radical Banana Racer for being so convenient to use. And it has an abundance of room. For PBP a smaller one would be even better, but it works very well. Add a dry bag to keep stuff that can't get wet. I have the Scarab as well, but I don't really like it.
Fenders, I have plenty experience riding in rain. Did I mention I am from Norway? I use fenders on my upright, but not on the Vendetta. The spray from the rear wheel is handled with some tape across the neck rest posts. The spray from the front wheel has never bothered me. The number one advice I can give for rain is neoprene gloves. Perhaps one size up, so you can get them on and off easily when wet. They still get wet. All "waterproof" gloves do (apart from dishwashing gloves). But they will keep your hands warm enough for temps down to 5-10 degrees C. Also wool socks and merino base layer. On the off chance that they forecast cold nights (like 3 C) with lots of rain, you would need to add a pair of "waterproof" winter gloves. Or just endure it until the next control.
For hydration, I have one bottle easily available under the boom, and two more behind the neck rest. That is more than enough for a PBP stage.
As for video, you only need one large micro SD card. That can give you 8 hours of footage, which is way more than you'd want to edit. You only need one battery too, but you need to be able to connect to a battery bank or dynamo every now and then.
Pacing strategy for long rides is interesting. The thing is, it only applies for half of day 1. For the rest of the ride you will go at your comfortable speed whether you want to or not (unless you're really committed to breaking some sort of record). When on an upright, I have found I really need to get enough carbs to avoid a slump at about 150-200 km. I use sports drinks and or a top tube bag full of candy to take care of that. But if the slump comes, it's gone after a rest stop with food. And at that point my body seems to have gotten the point that we're on a long ride, and adapted to fat burning. When on the Vendetta, I can keep a good pace with lower intensity. What's more, my heart rate naturally drops about 10 bpm just due to the reclining. These things seem to make a big difference for me, and I generally don't get that slump at all. On the 1000 km last weekend, I only had sports drink for my initial load of 3 bottles, and little candy. But at no point did I feel exhausted.
Plans for PBP
- I’m in group F starting Sunday at 5:15. My goal is to do the first 600K in one go and get to the outskirts of Brest (where I have a hotel room) within 30 hours. I think I’ll be able to power through the night, but will likely need a nap at dawn or maybe in the afternoon. Still, 25:30 moving hours… maybe a little less if I ride with groups… leaves 0:30 for each of the controls and 1:00 to nap. Maybe worst case I get to Brest (Landerneau actually) closer to 1 or 2. My big insight from the 600K is that I need the stopover to be 3-4 hours sleeping and no more than 1 hour screwing around with a shower and food and coffee and conversation. I have plenty of room in my solo aero bag so I should probably buy dinner and breakfast food in Carhaix and bring it with me to the hotel.
- Then I can break the return into two 300K days, expecting to drop speed on each day. If I can get on the road by 6:00AM on Monday, I can get into Fougeres where my wife will have a room, by 11 or midnight (15 hours at 13.5mph +2-3 hours at controls), and then getting out early on try to make it into Rambouillet by midnight on Weds with a 12.5mph or 13mph pace.
- Backup I guess would be to sleep in Loudeac or Carhaix on the way out if riding through the night doesn’t agree with me… and then play it by ear. How’s that for a non-plan. Part of me feels like working out the logistics of this scenario is a little like trying to figure out how to get back to Paris if you scratch… having the knowledge will work against you in the dark hours.
