Sorry if this has been brought up in the thread before, but could anyone weigh in on the S5's long distance comfort?

Now that I've got a dedicated gravel bike rather than just one bike to do it all, I'm considern going full aero on my road bike - and I've always been eyeing the S5. That being said, my primary focus is on long distance rides (potentially with several consecutive days in the saddle). Reach/stack-wise, I could emulate my tried long distance fit on the S5 without too many spacers. And with the current S5 supporting up to 34mm tires, I'm wondering what speaks against using this bike for endurance rides as well. I've never had a bike with such extreme tube shapes - is the frame compliance really so much worse that it makes a noticable difference even when using wide tires?

I have no first hand experience, but i watched a review on youtube and that guy said he felt beat up and claimed it wasn't what he would buy as an everyday bike. To be really honest, i believe the later "semi-aero" bikes, or slimmer and lighter bikes are what's on the radar now for a reason. Not only the weight, but also ride feel and that full blown aero can be a bit sluggish. Only way to really get your own idea of this, would probably be to rent a bike if you have the chance?

But i am certain it's like you mention, there's a reason the bike frame can fit 34mm tires. Part from that, i would also pick S5 if i went full aero, so i understand your thoughts very well. Personally i think i'd pick the new Madone (typically what i would call a semi-aero) but that's because i am not certain i could manage the ride feel of these machines.

Probably the best standard paint so far. But the weight seems to low. Have you really put the complete bike on a scale?

The math certainly says this will work. But before you go down that road, see if you can get a test ride as you may find the S5 sluggish and dead feeling with the big tires. A lighter, more compliant frame with slightly smaller tires will likely feel just as comfortable but with a more alive feeling to the ride. But it may really only be a question of which bike gets you "jazzed".

Thank you for the input, spud & wheelsONfire. : )
I actually happened upon a really good deal on an S5 frameset (56, five black) in the meantime and decided to bite the bullet. Just building it up at the moment; can't wait to give it a go. ^^

Here are the weights:

Frame (56, Five Black): 1018g
BB Rubber Plug: 6g
Front Derailleur Clamp / 1x Blank Plug: 10g / 6g
DI2 Kit: 13g
Derailleur Hanger: 16g

Fork (incl. Thru Axle Thread Attachment & Gap Spacer with Screws): 421g
Fork Tensioning Rod: 20g
Fork Tension Rod Insert: 18g

Seatpost: 248g
Seatpost Clamp: 24g

Stem: 134g
Stem Screws: 36g

Handlebar: 295g
Handlebar Screws: 25g
Computer Mount (with Screws): 28g

Front Thru Axle: 22g
Rear Thru Axle: 29g
Detachable Thru Axle Lever: 20g

Finally succeeded weight below 7 kilos!
6.685 thanks to Black Inc. 48/58 wheels; Comptufa prima tubeless 28 tyres; Overfast carbon thru axels and titanium bolts.

[spdntrxi]

nice.. and nicer weight.

I was shocked when I weighed a stock 51cm S5 Dura Ace and it was 7.8kg without pedels.

Hello all,
sharing my a bit "specific" build. Just have room for a single bike in my apartment, so I opted for the S5 with a TT aerobars setup instead of a dedicated TT bike. Im guessing this is now one of the lightest possible TT configurations but still not a dedicated one. The mount adaptors I fabricated at home.

Really suprised with the position achived in the end, super comfterable while still super fast.. I guess it would rival some dedicated setups with ease especialy on hilly courses.

Still have to weight the badboy tho, the photos are a bit old allready... the stem was droped all the way so it is without the spacers, and I replaced the selle italia with a Fizik adaptive TT seat that improves the extensions position and is far more forgiving on 150km + rides in all positions.

[Weltverloren]

Super cool Bijabec; this is right up my alley. : )
I'm using the Deda Jet bars with FastTT adapters on my S5 at the moment, but your's look great as well. I'm especially curious about the adapters.
What aero bars and adapters are those?

[Upcountry]

Same! As an Ultra guy, I'm way on board with this build! Really well done!

Thx to both;

The aerobars are by Sync ergonomics, an australian manufacturer that 3d prints the extensions which are customisable in 3 parameters based on rider specification. As its 3d printed titanium they should last a lifetime and in the long run I intend to mount them on a dedicated TT build.

As for the mount adapters, native Sync mounting offset is 125 mm - while the cervelo Stem mount system is at 135 mm. For briding the gap I used the native Argon 135-125mm adapted by sync, which also has a -10mm offset for a better position of the aero bars.

As for the final clamp adapters - basicly I made them custom. They are based on the Fast TTT adapters - the bottom piece that acts as a clamp, but modified so that they enable cabel routing for the satelite switches in the aerobar handles. The 50mm titanium bolts just run through and screw in to the native Sync system adapters. For the finish I just protected the bars and spray painted the assembely with matte black came out looking like out of the factory

[Bijabec]

Maybe just this addon - as for comfort, I find the geometry perfect even for Ultra distance 250km+; have ridden more than 300km on the setup in one go with absolutly no issues with a total abstence of back pain. Which I find quite remarkable as said I droped the stem completly so I am not using any spacers at the moment.

I previously rode 2019 S works Venge the same frame size 56; and the back issues were a constant issue.

Also the Fizik transiro adaptive pictured bellow that completed the setup is comfterable beyond words for long distance, and also enables a proper position when on the aero bars with a move to the front of the seat.



Really positivly suprsed on the quality of the aero position which is possible to achive on this setup.

[Weltverloren]

Thanks for all the details! It looks like a really great setup!

I'm also into long distance cycling and just picked up an S5 recently. I was using an Aspero-5 with a road wheelset, but after getting a dedicated offroad ride and noticing that I can replicate my fit on the S5 I thought I'd go full aero for my road ultra setup. I'm basically using the drivetrain from my Aspero with a larger 46T chainring and a lightweight Garbaruk cassette.
I also picked up the Hylix seatpost and a set of Enve SES RaceDays to shave off some more weight, but they're not on the bike yet.



One thing that I'm still trying to figure out is the storage. For really long distances requiring sleeping gear etc. I'm throwing on the Tailfin AeroPack, but I don't know where to store my pump and tools on my daily rides. Only having had Gravel Bikes with top tube mounts before, I got used to keeping all my essentials in a bolt-on top tube bag, but the S5 has no mounts and I don't like the look of strap-on bags. And all of the saddle bags I tried so far (which were able to fit a micro pump) didn't fit properly. I'm contemplating going for a 3D-printed solution like this one. How are you solving this?

Nice to see another simmilar build, nice job. Was expecting to run in to more based on that the stem and handlebar clamps allow for it.

For the bags.. really like the back printed option - for my needs I only use the bag for rides above 200 and more in the 300 range. And for those I use the new tailfin frame bag that fits perfectly and allows me to fill it with an absurd amount of food, battary pack to fill the wahoo and phone and etc...

For rides up to 200km I just use the USWC Ourlander pro / Race pro; the small 2l hydeation backpack. Superlight, ultra small and seems to approve the CDP and aero position as it acts as a back hump! Love that thing, and its quite cheap!
