Very curious as I’m planning next bike build. I am assuming it’s not a disc brake bike?
If I’m seeing correctly the P5x outweighs the p5?
Will the brands i.e. Specialized, Cervelo post accurate frameset weights or are they misleading?

Full setup with disc wheel is 18.5 pounds. Can’t beat it.
Here’s the link to a different thread that provides more info.
Interesting question. I think the 18 lbs barrier is going to be pretty hard to beat for many bikes. One of the issues is the amount of chunky aluminum that goes into the cockpit. For example, the Speed Concept stem and riser are just one big chunk of alminum. I think the ProTour guys get custom carbon risers, but getting below 18 without some custom stuff will be hard and probably require something like a Liteweight disc and custom spacers (Drag2Zero was making custom carbon Shiv TT spacers, but they were like 500$). 1x will also help. eTap is pretty minimalist with a light battery. Shifters and 8 feet of cable and housing add up.
P5X will outweigh the P5 by a country mile. Ventum definitely not a light bike either. Both bikes you are buying for supposed aero gains. If you are buying a conventional bike and worried about weight then I’d be looking at the figures of each.
Ventum is not the lightest frame… super comfortable and amazingly efficient, still climbs really well. By carefully selecting components, you can build it sub-18. If weight is your criteria, then Scott should be up on your list.
Is there a particular reason you are focused on weights of tri bikes? Unless you are racing a large amount of courses with big climbs there are several other factors that trump weight. Bike fit, aero, and comfort are three that come to mind.
Climbing…
Get everything set up pretty in a wind tunnel is one thing, but climbing on a hilly course is another even Kona has (I believe well over 4K feet of elevation gain). This has me thinking that is why the P5X isn’t performing in the REAL world.
Frederick Van L. NOT using the P5X in last hilly IM certainly raised an eyebrow.
A Disc brake setup can not be light.
Maybe give up a little aero for ability to ascent faster?
If “light” is your overarching priority, see if you can scare up a NOS Cannondale Slice Hi-Mod.

I wonder where the Trek falls now that they don’t offer it with the OCLV 6 carbon anymore?

Wow the felt is a fatty boomba
.
Awesome very much appreciated.

and there is room for weightloss if you really cared (more importantly its still a very fast bike and with the new rear break adapter i guess the rear break breaks now lol )

GCN just released another youtube video about aero vs weight. Basically unless you are going up about a 6% or steeper gradient, aero trumps weight. Even when you go up a steeper gradient, you still have to come back down, so aero will catch back up almost all the time anyway.
The P5 is as aero as the P5X, so maybe that is why FvL chose to ride it instead.
4,000 feet of climbing over 112miles isn’t very much at all. I don’t live in a hilly area, but I would struggle to ride 112miles without climbing more than that.
I just built up a new Speed Concept with 808’s, Dura Ace Di2, Dash saddle and other pretty high end bits and it’s noticebly heavier than my previous 9 series SC. Every time I lift it I am amazed at how heavy it is! I recall my previous Gen 2 9 series SC was pretty light and with a similar build.

Yeah, small frame set and $$$$$ in fragile parts.
Really something I’d ride everyday…
That was a Medium Frameset FYI. Not sure what you consider fragile on that build. Sram drivetrain, Dash wheels/saddle, Alpha X bars. Mostly standard stuff, just lots of care in the details.

Lightening crank might be considered on the less durable side, but that’s about it… the rest of the build is durable enough for racing and training.

You should’ve mentioned that budget is a constrictor lol someone asked for a light bike setup and well you should know that the lighter anything is the more expensive it gets!!!
Was that 90s quintana roo kilo frame really 1 kilo? You could prolly pick one of those up now for a few hundred built up
I can’t believe that felt is last on that graph… I picked one up once and it felt like a tennis racket
