I'm so confused. I'm looking to get a new bike after a car accident. $5-10k is fine. But, what in the world to get? I like the new Specialized tarmac coming out. Anything contending with it? Disc is giving me headaches.

My Emonda Disc is sitting at 15lbs 14oz, though I could get it down to 15. Beyond that requires some superlight components.

Lighter tubeless tires (-3oz total)
1oz of sealant per tire instead of 1.5oz (-1oz total)
Switch from ENVE SES 5.6 Disc with White CLD hubs to 3.4s with DT Swiss 240S hubs (-4oz)
Bontrager XXX integrated bar/stem (-3.5oz)
Lizard Skins DSP 1.8mm vs 3.2mm (-.5oz)
Bontrager XXX saddle (-2oz)
Lighter PM than Garmin Vectors (-2oz)

Canyon Ultimate SLX is going to be the closest thing to the new Tarmac (semi aero, lightweight) available in disc that I can think of. I think with any of them you are going to need some exotic parts to get below 15lbs.

Still quite difficult with standard parts. I am struggling for the same reason, starting from a suitable lightweight, aero , tubeless, wide wheelset.

if 36mm U shape is aero enough for you:
~1430g Nox Falkor 36D (415g) with DT240

Depends of course on the definition of lightweight and aero.

A little fancier.

A lot fancier and tubular.

If you're about weight per dollar. Rose has either the X-lite CWX or the X-lite CDX at 6,95kg. So thats 15lbs and 5oz.
That's with weight to save on saddle, handlebar, stem and on wheels. As well as plenty of budget to do so.
Then again, you'd be missing out on that superbike cool factor, that an S-works or even Canyon can get you :).

See my sig :wink: The current weight of the Endurace is 6.9 kg, incl garmin 520, so ready to ride. Not a single exotic part on it, and still on the R785 shifters, but all the small things add up (rim tape, innertubes, bar tape, bolts, Superlogic finishing kit, Ti spindles etc) If Scott respects his promise toward my dealer, the Endurace will be replaced by a 2018 addict rc premium disc within 4 weeks. In the end, I will only keep frameset and the 9170 groupset, all the other components will be swapped between the Scott and the Endurace. Target is something like 6,6kg. The Endurce will be sold with the donor parts off the Addict.

When I was toying with the idea of building a "do it all" bike, I put together a spreadsheet for an Eriksen build. This might be helpful to see the different weights that go into a disc build. I'm missing hydraulic fluid from this build. Also, I probably would be a little more conservative with the wheels and use Tune Mig70/Mag170 hubs instead of Extralite.

For reference, a 3T Strada would drop 50g on the uncut fork and 522g on the frame, which would put you in a respectable 6.5kg range.

I'm in the same position. I can achieve what you want but with DIY build with a workswell r081 frame. 6.5-7.0kg. Aero, disc frame.

For branded choices you will have to settle for aeroish bikes like emonda disc. The only aero disc I know is the aeroad and that thing is heavy.

Disc and aero both have weight penalties.

Giant is releasing their new propel disc soon. You might want to check it out. Also not to forget comfort with such a lovely allrounder. How about a trek domane disc? There you got comfort for a small weight penalty. That is maybe the last bike you'll ever need.

Ahh yes the S3 disc. How could I forget. :D Heavy but real nice looking.

What about the F10 disc and 3t strada disc. Hows the weight? Are they real aero bikes or another emonda type? For the F10 I'm guessing yes... but the weight?

Not pure aero, but the new Cervelo R5d is somewhat aero, and could probably be easily gotten down to <6.8 kg.
