2020 Aethos Sub UCI weight Specialized.

[okx]

The bike without cutting the fork, with Ultegra pedals, and quick-mount and all these changes came in 7.45 Kg.

I think you can make some good progress here. Mine comes in at 7.0 Kg with frame size 54 and the WTO45s. Obviously the 33s are lighter and the 52 frame may be a few grammes lighter too - depending on your paint. Not sure how the other components stack up, but guessing sub 7 could be on with the 33s and a few more small tweaks.

Which brake calipers you have used?
Does stock brake caliper fit's in front?

Hi! I used a 140mm flat mount caliper on the front (you can mount it to the custom mount plate that ships with the frame) and a 160mm flat mount rear caliper. I have 160mm discs front and rear.

A full summary of the issues for those interested:

The Aethos front fork has a non-standard mounting so they ship it with a custom mounting plate. Shimano/Sram calipers are all sized for 140mm flat mount and provide adapter plates for use with 160mm. If you are fitting Shimano/Sram you simply discard the provided adapter plate on the front and use the Aethos one instead. This means you cannot actually use a 140mm disc on the Aethos fork at all (unless perhaps you get very handy and make your own homebrew mount).

The Campag 140mm caliper has the same mounting thread position as the Shimano/Sram calipers (without the adapter plate) so can be used on the front fork just fine. The Campag 160mm calipers are designed to be mounted without the need for an adaptor plate, which is nice and all - until a frame maker does this kind of thing.

The lesson I learned: Next time I impulse buy a Campag groupset (without a frame in mind) because the price on Merlin is so good, I will get 140mm because you can always adapt 140->160 not the other way.

Thanks for info
At the moment I have Campy 12sp with both 160 rotors on Pinarello gan and I'm thinking to get Aethos frameset and use all parts from Pinarello.
Just need to find where I can get campy 140 brake caliper in EU... Other Alternative - buy ultegra di2 groupset, from weight perspective, ultegra di2 should be very similar to campy 12sp record groups set.

Look for alternative like hope or magura instead of original.

There's more pictures of him riding it.
It has big S-Works logos on the downtube which imo
Looks much better

What aftermarket thru axles can you recommend to save a few grams, that still are robust?

There were people already trying that and they concluded basically any. Apparently specialized went WW on the thru axles.

[FlatlandClimber]

So any will work, or the standard thru axles are WW already?

Yeah, I guess you have to go back a couple of pagees or maybe even in another thread I don't recall but people made the same questions and they concluded that the standard ta are ww already. No savings to be had on that part.

[FlatlandClimber]

Okay, fair enough! Thanks

According toe french website Matosvélo also Dries Devenys will be riding the Aethos in the next mountainstages in the Tour.

A queston for the Aethos owners.
My current stable of bikes is an 'old' 'new Focus Izalco Max rimbrake bike 6.5kg with Bora Ultra clincher wheels and new Cannondale Super Six Evo (EF Education colors) of 7.1 (Roval Rapide clx) or 6.9 (Roval Aplinist CLX) kg.
I like both but I prefer the ride feeling of the Focus. Super light, stiff, agile, playfull, comfort.
In a way I believe I could compare the Focus to the Aethos and the Cannondale to an SL7.
For me it seems like the Aethos is a modern Focus Izalco Max.
Would somebody have an idea of the ride quality of an Aethos is close to the Focus?

Did a little tuning on my Aethos and in true WW fashion, it got 150g heavier
I will be using it on a trip through the Alps, but primarily for Haute Route Dolomites.
Despite that being mainly mega steep climbs, there will be flat sections to be raced, so I tuned the bike for more Allround speed and comfort:
- Schmolke Oversized TLO handlebar instead of MCFK Aero (for more comfort)
- more and thicker bar tape (more comfort, too)
- climbing shifters, to be able to spend more times in the tops
- Rapide instead of Bontrager RsL 37 (+50g)
- Silca Tubes instead of Aerothan (+60g)
- DA instead of XTR Rotors (likely to be swapped again, +20g)
- Red Max instead of Force wide Rear mech (-30g)
- CS OSPW Ltd Edition (+15g)

I am really looking forward to how this will fare in the mountains, but I think This might be great.






(Light adds 20g and race day pedals are 35g lighter... but then again there is a 430g saddle bag, bottles and a rider to be added ).

[Mr.Gib]

What was your reasoning to swith to Silca Tubes instead of Aerothan?

[FlatlandClimber]

What was your reasoning to swith to Silca Tubes instead of Aerothan?

Rolling resistance and comfort.

Sounds like you have a great trip planned. Enjoy it! Will you be using a 46-33 and 33-10?

[FlatlandClimber]

I have a 48/35 on the front, and 10-33 on the back, but I am bringing the 10-36 along. I actually used that during Haute Route Switzerland, and it was the Right Choice.
People were looking pretty jealous when I was spinning up a 13% grade, while everyone else was forced to stand.
