What are the differences between the two frames? Just weight? If so does anyone have specifics?

It appears the 6 series has a slightly lighter & stiffer frame according to Trek's website. I would bet the average rider wouldn't notice a bit of difference? For me it would come down to wanting better components, I would rather have the 5.9 with Di2 over the 6.2 with std Ultegra because I have been spoiled with the Di2 on my new bike and will never have a road bike without it.

I have the 5.9 with Di2 and love it!!!

half pound lighter, better OCLV carbon, a bit more comfortable, and a bit more money. Ultegra is dog heavy. If you want to save a little weight, buy the cheaper frame and fit it with SRAM Red 11S.

They offer the Domane 5.9 with all three groups for the same price (Ultegra 6800 Di2, DA 9000 & Red 22). Whereas the 6.2, for $330 more is Ultegra 6800. Personally I think the 5 series with any of the available drivetrain options is a better buy than a 6 series with 6800. If you're considering a $4500+ bike, than $300 bucks or so shouldn't really break the bank.

We stock the 5.2 and the 6.2 in our shop and the ride quality for $900 more dollars isn't noticeable. I'm just as fast, just as comfortable on both bikes across the same route. I've probably logged about 300-400 miles on each and my daily drive is a 4 series Domane. The step up from the 4 series (to even just the 5 series) is definitely noticeable.

I did notice a detectible difference in the 4 series to the 5 series on my test rides. I couldn't detect any difference in 5 and 6, which is why I got 5.9 with the Di2.

If you are contemplating a Project One design, Trek offers the 4- and 6-series in that program but not the 5-series.

I ordered a Project One late last year and went with the 6-series and have no regrets. The bike rides great.

This is really what I'm considering - a Project 1 6 series or a stock 5 series. Money isn't the major factor, but I don't want to pay for more expensive things without getting a real benefit.

The big thing you get is a nice looking Project One bike.

The last P1 I saw, my riding partner and I both went "That's a Trek?! When did they start doing cool paint jobs?" I don't think Trek's are bad looking, they just tend to be a little plain. The generic Trek paint job: one color, says Trek on the downtube, and some accent pin-striping.

For me, the big driver for going P1 was that I wanted SRAM Force 22. There's no way to get a Domane with that groupset other than to go P1. Initially, I was going to get a 4-series and when I didn't really care for any of the Select finishes, my wife told me to splurge for a custom finish. I told her that instead of the paint job, I'd rather have the 6-series frame and one of the 6-series Select finishes that I did like. That worked well for me as I have a finish and a bike that I really like and that doesn't look like anything else that I pass on the local roads.

Good luck with your decision.

I'd prefer Force 22 also. That's why I'm leaning toward the 6-series while realizing that I'm paying a premium for the lighter frame. First I've got to heal from a recent bike accident (broken femur and broken bike), start riding again to make sure everything healed correctly, and then I'll order a new bike. I've got plenty of time on my hands now to think about what to get next.

I hope that you heal up fully and are able to ride soon. Have fun playing with the Project One builder on Trek's website - it can be rather addicting.

What's the point in saving 500 grams, or a 1,000 grams if you aren't professionally racing? Not saying any of you aren't, but it only seems useful if you can absolutely lose no body weight and have to lose weight on the bike instead.

Go with the series 6 & custom paint job and build something awesome and unique.

When I was looking at the 5 series, I wanted to update to the Race Lite wheelset and GS derailleur, and that jumped the price into the ballpark of a 6 series. FWIW, the price difference between a 6.2 and a 6 series P1 is negligible.

The more climbing you do, the more that weight matters.

I own a Domane 6, and I rode a Domane 5 for about 60 miles of demo time. I didn't think the difference was drastic, but I definitely thought it was noticeable. I didn't notice the weight so much, but I did notice the stiffness, especially when getting out of the saddle. I'm about 205lbs and ride a 62cm, so I might flex the frame a bit more than average.

Since I wanted SRAM Red and the only way to get that was Project One, and the only frame (then) on Project One was the 6, that made my decision easy.

5000ish miles later and I'm still happy with the bike.

My wife also got a Project One Madone 7 with custom paint and it looks killer.
