The systemsix is weird to me. Some pics of I've seen of it make it look gorgeous. Others it looks butt ugly.

The "overbite" (that notch between the head tube and fork) is strange looking.

I just think it's funny that they're coming out with an aero bike after years of saying they didn't need one in the lineup because those fat round tubes on their regular road bike were already aero optimized. It's also a bit lame that they spec'd an extremely fragile tire on the bike just because it happens to test well in a wind tunnel and now they can claim their bike is more aero than the Madone.

With the new Systemsix, the only price I'm seeing is $7499 with race wheels, di2, and a power2max powermeter. Honestly, not a terrible price for a full build, himod bike. That's the same price as the top of the line canyon disc brake bike and you don't have to deal with buying a canyon and all of those head aches.

An unactivated power meter. You have to pay $499 for it to be activated.

The new time machine looks sweet. Integrated storage solutions are so hot right now.

Really? What does that require? Installing a battery?

Weird!

From the CyclingTips review:

Cannondale has partnered with power2max for its top-end models. The Hi-MOD Dura-Ace Di2, Hi-MOD Ultegra Di2 and Hi-MOD Dura-Ace Womens builds all come with Cannondale’s own HollowGram SiSL2, BB30 chainset combined with power2max’s NG Eco powermeter. The niggly bit here though is that unless you pay the $490/€490 “activation fee” to power2max, the powermeter will, in essence, be redundant.

It was explained at the SystemSix launch that the power2max activation fee could be something of a selling point for retailers. The industry has a habit of not selling bikes at full RRP, and if they do it’s usually a case of the retailer throwing in freebies. A free activation of a powermeter on a $7,499 or $10,999 model bike may very well be the bargaining chip a shop needs.
Sounds like a dreadful idea to me.

SystemSix may be a bit too pricey for me, our team is a Cannondale shop so I'll get a discount but I wasn't looking to go over 5k and wanted an electonic gruppo.

less maintenance on hydraulic components
no more of that haunting squealing

disadvantages:
safety (we're about to find out; I doubt it's anymore dangerous than low spoke count wheels)
cost (greater upfront cost compared to calipers, but imo less long term cost due to long lasting rims)
weight/aero (weight not really an issue. aero needs more data)
rotors easily bend (pita, but manageable)
wheel compatibility (bring your own for the wheel pit)

i personally think the pros outweigh the cons. what do other people think?

anyone work in the industry? will the component manufacturers come out with disc brake options in the near future?
I have a Trek Emonda. The year I got it disc brakes weren't being put on it. Plus the color scheme was the exact I wanted on sale so I was excited. I also have a Trek Crossrip that has disc brakes for weather that isn't great.

My fear was people eventually won' be able to have the parts to repair caliper brakes if they go totally out...

I enjoy using both.

Is that really a fear? Are there parts from even 20 years ago that you can't buy? I see 8 and 9 speed stuff for sale on ebay all the time. And with the billions of brake calipers out there, I think they're be no fear of them ever going completely away. I have 8 or 9 pairs myself!

yeah but I put together a bike for Eroica this year... fudge man.. I'd be that much closer to a new aero bike if I shunned the whole thing.

also not like brake calipers really wear out.

it also looks like they designed the bike with the bottle and cages in mind, which is something i was surprised nobody has done sooner. but then again, i remember reading that when you put a rider on the bikes, their differences in drag diminishes, I guess due to the much larger margin of error. so it really begs the question whether having a super aero frame is really worth while..

Not the headache of buying it.. The headache of maintaining it. Many I've talked to complain about the difficulty to get propreitary replacement parts in a timely manner. Different sized steerers, unique bolts etc.

Granted it's only one data point but review not so favorable. For a 10k+ bike seems like a shame.
Key takeaways.
Squerrely with crosswind at speed.
Bottle holders not that easy get bottles out of.
The custom handlebars might not be for everyone.

^ anecdotal at this point..

squirrels could be wheels.. rider is not large 5'8ish and looks skinny.. and 5'8' and fat and will feel a push on 60+mm wheels
New holders .. they will break in
Custom bars are never for anyone.. atleast they rotate, I think 25mm size has him bummed. They look good to me as does the stem.

Yeah I agree anecdotal, so will see what other reviewers say in real world once it hits mass market.

I'll let you know since it's my #1 contender at the moment. However I'm not getting the entire bike and definitely not those wheels.... I'll get ENVE's

Yeah report back. I own the none disk version, and was thinking of getting disk one down the road.

This latest crop of disc aero bikes has me really considering one for my next purchase in 2-3 years.
I can't justify the 'new' cost, but once the used market matures there should be some mega deals to be had.

Side topic, other than weight and aerodynamics (and bling), which are all very close at this point, how long until the basement falls out on the high-end wheel market?
Switching to disc is removing the major component in why no-name carbon wheels were/are so scary. Any properly built/trued wheel isn't very likely to just explode on it's own now that heat/wear is no longer a factor.

I dont know but once my disc gravel/road bike is built I'm fire selling all my high end carbon (enve) I have already off'd my full disc TT wheels and some other stuff. Eventually in 1-2 years I'll go disc on my TT bike as well and be disc only. I'm not going to wait for the basement.. but I think the basement is 2-3 or more years away.

i think resin melting under heavy breaking has not been a problem for some time now. It was when the open mould wheels first came out that this happened. people were using low Tg resin to make the wheels. the open mould distributors that are still around (yoeleo, dengfu, farsports, etc) use good quality stuff for their builds. so there's nothing to worry about as far as safety goes.
