Frame weights have gone up, but only very slightly. According to Trek, the current 56cm Madone 9 frame comes in at 1,053g, plus 376g for the matching fork. Claimed weight for the new rim-brake Madone SLR frame and fork are 1,112g and 378g, respectively, while the disc-brake version is slightly heavier still at 1,131g and 421g. Even so, Trek says the complete bike weights are identical for the rim-brake version — 7.1kg (15.65lb) for a 56cm size, without pedals. Claimed weight for the disc-brake Madone SLR is expectedly heavier, at 7.5kg (16.53lb), but supposedly still within the design targets.

Maybe a mixup? White paper claims the Rim Brake is around 400g lighter.CallumRD1 wrote: ↑Fri Jul 06, 2018 4:15 pmFrom a Velonews first ride writeup:Shrike wrote: ↑Fri Jul 06, 2018 2:51 pmThe new Madone has more drag than the previous model:
Though it doesn't specify the difference between the new Rim and Disc Brake models. They say 'average', so I'm guessing that's an average of the Rim and Disc models, which would be a useless and disingenuous figure. Perhaps they mean Rim v Rim, and 'average' means across repeated tests. Either way leaves the issue in the air. What is the drag for the new Rim bike and what is the drag for the new Disc bike.Madone SLR White Paper wrote:Final new Madone numbers show an average of 3216g across a -12.5° to 12.5° yaw sweep vs the current Madone at 3202g. A 14g difference..
"But if you want to go faster, opt for the disc brake-equipped bike. The disc frame is faster than the rim brake version in aero testing by about 15 grams of drag — not to mention lighter."

Would love it if what velonews wrote is true though. That'd ruffle some feathers!

Velonews is wrong.
Trek’s claim is the disc bike is 15g of drag faster. It’s definitely not a lighter bike, just a more slippery one.

Cycling Weekly have a video up.
New Madone has '10 to 20g less drag that the last Rim Brake version' and the new Disc Brake version has a 'watt or two max saving over the current Rim Brake version'.

He seems to be saying that the new Disc Brake version is a watt or two faster than both the new and old Rim Brake version.

The current Madone 9.0 seems a bargain with 600 OCLV compared to the new SL with 500.TobinHatesYou wrote: ↑Fri Jul 06, 2018 4:53 pm
The SL is really just a last gen Madone with tweaks and downgraded carbon.

That handlebar looks like a smart design. I’m quite particular about my handlebar angle, and this provides 5 degrees of adjustment which seems reasonable yet hoses and housings are all hidden.
I was waiting for a Madone designed in a similar fashion as the Venge, Timemachine Road and SystemSIX, but have to give credit to Trek for sticking to their guns. The Madone seems to be living & breathing on the IsoSpeed more than ever, which will be a polarizing feature for sure.

How does each level of Trek carbon stack up against each other? Basically, is 600 that much more valuable than 500?hlvd wrote: ↑Fri Jul 06, 2018 5:26 pmThe current Madone 9.0 seems a bargain with 600 OCLV compared to the new SL with 500.TobinHatesYou wrote: ↑Fri Jul 06, 2018 4:53 pm

Frame vs bike innit.
Several manufacturers have disc frames lighter than rim frames (though they never factor in the axles), but the like for like built bikes are always heavier in disc. The componentry difference is massive in comparison.

Trek's whitepaper does claim the disc frame is lighter. Coincidentally, by 15g - though the fork is 33g heavier. Couldn't be bothered to trawl through the small parts but their list is exceptionally detailed. Kudos to Trek.
Don't know about the real impact of Isospeed (have ridden quite a lot on Gen 1 Boone), but where Trek scores in this round vs the others, is definitely the color schemes.
Minimum bike categories required in the stable:
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
Aero bike | GC bike | GC rim bike | Climbing bike | Climbing rim bike | Classics bike | Gravel bike | TT bike | Indoors bike
Madone 9.0 with OCLV 600 seems to be 390 grams lighter than the new Madone SL 6 with OCLV 500. The bikes are otherwise identical (except for a slightly lighter saddle in the older Madone 9.0). That's a pretty big difference.
