So it means you suggest size 57 for me as well? I'm between sizes and I still not sure.

I have pretty much decided to order one of the X Lite 6 next year. Also interested in feedback, especially on how the weight comes in. There was a recent good review in the granfondo online magazine. Still debating on whether to go for the Dura Ace Di2 or Etap.

Yes, pretty much. If you can, and you're comfortable on your current bike, then go for the size which is closest to your current bike. If it isn't really going to work for either size (more than ~2cm out) then go for a different frame.
:hello:
Cannondale Supersix 2008 (weight: 7.3kg)
B'twin Triban 540 (in bits)
Vitus "Benotto" 979 (weight: :? )

A few years ago Rose sent a specially light frameset for a Tour magazine test. They also bought the same bike anonymously and it was several hundred grams heavier. Now the first customer review for the X-Lite Four complains about a higher weight than claimed, although he even opted for a lighter wheelset...

And the Grand Fondo review praises the Zipp 454 NSW for their crosswind stability. Everyone who tried them complains about a "bitchy" behaviour in crosswinds. And the Tour magazine test supports this... So if Grand Fondo measures a spot on weight I would be a bit sceptical at least.

We will have to wait for someone who rebuilds his bike, before we get real world weights...

But if the really good aerodynamics are just because of the Kamm tail tubes, we will see these on more frames in the future. :D

Edit: That's the 222 watts setup... (Tour Mag. 3/2018 also stated 212 watts, that was a typo).

As you've said I think Gran Fondo have just quoted the listed weights rather than real world. A buyer of the bike stated on Bikeradar forum that it came in 200-300g heavier than quoted.

It's a shame. But as Peter Denk stated here, it's easy to hold a certain weight with 50 to 100 framesets, but mass production is a different story:

https://www.bikeradar.com/gear/article/ ... ogy-30298/

But I also noticed that they state the same weight for Dura Ace / Dura Ace DI2 and Red / Red eTap... So maybe those claimed weights will be corrected soon.

And does anyone have Tour Issue 3/2018 and can tell what wheels and tires were used, when measuring the 212 watts at 45km/h?

It seems to be 222 watts with stock wheels.

The Pinarello F10 with Mavic CXR Ultimate 60 C and 23mm tires was 202 watts, with Zipp 303 and 25mm tires 213 watts...

And the Tarmac SL also has weight issues (52 and 56cm frames):

I'm 186 cm tall and 89 cm inside leg - do I have to order size 57 or 59 ?

Thank you.

He because inside leg for 59 frame is 88-91 i recommend 59.
My X-LITE FOUR DISC FORCE is around 7,3 kg in 57 cm so its around the weight producer declared. My demo X-LITE SIX Dura Ace 57 is about 6,45 kg which is fair because PRC 1400 Spline upgrade (Mavic R-SYS are 200 g lighter).
Regarding the issue with frames weight in test few years ago: TOUR magazine as spy shopper bought XEON CGF in the moment when ROSE company changed frame maker. The boss Erwin Rose apologized for that incident.

The bikes have not only been heavier in the Tour magazine test, you can find several customers in the forums with that issue. And now the first X-Lite Four customer review on the Rose homepage (verified buyer) states the same...

And on the homepage the weights of Dura Ace and Dura Ace DI2 (and SRAM Red and SRAM eTap) bikes are also exactely the same. Electronic shifting will add at least 150g with the same other parts. Those weights can't be true for both types.
