Something must be wrong with the Trek paper if it claims sub 900 gram frame weights. The actual 2019 Trek Madone SLR 9 Disc webpage says the weight for a 56cm bike is 7.65kg, 16.86 pounds. I'm pretty sure its almost physically impossible to go from a sub 900 gram frame to a 16.86 POUND bicycle. Thats 14+ pounds of gear on a 2 pound frame. Dura Ace disc Di2 is 5 pounds (2400 grams). Wheels are 3.5 pounds. 6 pounds for bars, stem, tires, saddle?TobinHatesYou wrote: ↑Fri Jul 06, 2018 11:27 pmThere’s something very odd about their whitepaper values of 870g/885g. Even considering no paint, that is an extremely light aero frame.
Here was what CyclingTips quoted:
“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”
All that disco glitter adds a lot of weight.RussellS wrote: ↑Mon Jul 09, 2018 3:56 amSomething must be wrong with the Trek paper if it claims sub 900 gram frame weights.

They are centered. Those photos are just poorly framed and/or edited. Sometimes fork’s will be asymmetric so tires look off-center, but that’s not what is happening here.

As an FYI. These are starting to show up to the dealers, and I must say the thought that has gone into these is far and away much better than the previous versions. Even mechanical shifting at first glance.......before I actually have begun building it appears very easy with easy access all around. So much so I'm positive a home mechanic can build a frame-up with minimal difficulty. The previous version was absolutely horrendous and fussy. Have not seen the new rim brake in person yet.

We’ve already been over this. The Trek white paper is extremely detailed and weighs each individual component part of the frame. The sub 900 gram frame weight is literally just the mainframe part. The seat mast/Isospeed part is weighed seperately, as are all the other isospeed small parts and fixings, as are the mech hangers etc.
Yes, the Madone is not exactly a WW bike so would be an unlikely platform for a WW build, but the white paper is a WW dream, you could use it as your build sheet and literally track every replacement part in dropping weight. The issue of course with a bike like this is that so many parts are proprietary/integrated that you can't really replace them (at least with existing parts).wingguy wrote: ↑Sat Jul 14, 2018 2:39 pmWe’ve already been over this.

3700.00 for frame only. No seatmast, bar, or stem. The bar and stem are again proprietary, so no mixing. Bar is 400.00, stem is 300.00, not sure about mast, but am guessing 200.00. Very expensive and only frameset option right now is Project One.

I was also thinking of this. I think the new Madone is a super bike. But there ain't much to change or customize. Saddle, cassette, chain, cages, tires. And maybe the crankset-rings. I think regular cranks can fit the Trek BB90 or whatever system. So you could put a different crank in the bike. Guessing THM, Extralite, SRAM Red, AX make cranks to fit Trek system. Get some light rings. Drop 400 grams on the crank and rings. Drop 100-150 grams on the saddle from Berk or one of the other carbon wonder saddles. SRAM Red cassette would be 50 grams lighter than DA. Lighter tires and tubes. Maybe get the overall bike down to 15 pounds from the 16.5+ quoted weight. Maybe. And a roll of Ben Franklins.
My biggest complaint with the new Madone is the Isospeed suspension thing. I understand its nice to have it adjustable for everyone. Stiff for the racer, soft for the tourist. But I think Trek could have saved 200 grams if they had just picked one setting and done away with the extra weight and complication of having it adjustable. Pick something and make it permanently part of the frame. Then say its the greatest, bestest bike on earth. Just simpify everything.

So about $4600 for a retail theme P1. That’s still cheaper than a Venge frameset and $970 (before tax) more than a P1 Emonda frameset ($3500 + $130 seatmast cap.)
Also re: cranks...
Road BB90 is one of the most limited BB standards. You can’t use 30mm spindle cranks with it so most of the aftermarket options mentioned above are out.
