2019 SuperSix EVO Disc 6.96kg / 6.51kg

[AndreLM]

There is probably -50g of sealant per tire (~100g total).

Nice bike by the way!

That could be it I suppose, though hopefully there is still sealant in the Pro One TLEs. Maybe more in the Corsa Speeds.

And thank you!

Hello.

I see that you have changed the KNOT stem with a Deda DCR combo and that you still use KNOT spacers with Deda DCR stem.

Could yopu explain Deda DCR vs KNOT spacers compatibility ? Any problem to guide cables using this setup ?

Thanks for your help.

Breaking the 14lb barrier is tough with a disc bike for sure! Particularly with so much paint and a power meter. Might need tubulars..

Nice bike, enjoy!
How do the 2 setups compare?
Rovals vs Extralites?
Dura Ace rotors vs Ashimas?

Thank you!

Actually, that's the Farsports F1 bar/stem. I do have a Deda Alanera DCR bar/stem that I was planning on installing on my SystemSix, but I'm reconsidering. I'm not sure it really matters to take weight off that bike, particularly when there are no proprietary spacers to make the install clean, like with the F1.

Sadly, I haven't actually ridden the Extralites yet! Work has been waaay busy, for me even moreso in light of COVID-19, and I am riding almost exclusively indoors at the moment. I'll look to report here when I get a couple rides on them.

Have you tested Deda DCR stem with the KNOT spacers ?

I plan to install a Deda Vinci DCR stem with KNOT spacers and a FSA K-Force Compact 2019 bar (DCR compatible). But I would like to be sure that I can install the DEDA stem with Cannondale KNOT spacers to have a clean setup...

Thanks for your help.

Sorry, haven't even taken the first steps to installing the Alanera DCR on the SystemSix. I always assumed that it would require shaving down one of the Knot spacers to have it sit as flush as possible. Too bad there is no "transition spacer" available for the Alanera DCR like Farsports produced for the F1.

This update has been a long time coming, but I finally have my 2019 SuperSix EVO disc build complete. I'll cut to the chase, weight is 6.96kg with everyday wheels, and that is with powermeter, bottle cages, and combo Garmin/GoPro mount:



Here is the build sheet I used; a number of weights were estimates, and getting the frame painted added weight I'm sure (it added 17g to the Farsports bar/stem - see below), but in the end the spreadsheet was only 70g off the final measured weight, with the spreadsheet predicting 6.89kg compared to the actual 6.96kg weight:



Here are some photos of the complete bike, with emphasis on the F1 bar/stem, since it seems there is a good amount of interest in that item. I think it works really well on the EVO, and in particular I'm not sure why some have criticized the top cap - on mine, it is nice and flush and looks great (IMHO):






As you can see in the spreadsheet, I also have a pair of Extralite Cyberdisc wheels that I can throw on for a hillclimb effort. Based on measured weights, that should let me drop 565 grams from the build, for a hillclimb weight of 6.32kg, or 13.94 lbs. For us 'Muricans who continue to resist the metric system, under 14 lbs for a disc bike with some aero properties, powermeter, and cages and mounts is pretty good! I'm just waiting for the rotors, but will post photos with those wheels and hopefully my calculations are correct.

I've only ridden the bike a couple times so far (with the CLX50s), and it rides awesome!

looks awesome! great build...

Did you ever install a Deda Vinci DCR stem on your Cannondale? I am very interested in hearing if it is possible to place a Deda Vinci stem directly on top of the Cannodale KNOT cable collector headset cover (the one that has the hole in front for the cables to enter the headtube tunnel) without any additional KNOT or Vinci spacers. Do you know?

Or, alternatively, and this would not be as clean a solution, if it would be possible to completely leave out the cable collector headset cover just like the EF pro team does (see https://cdn-cyclingtips.pressidium.com/ ... dale-2.jpg), use a regular 5 mm headset cover or even a slamthatstem 2 mm headset over (https://www.certifiedslammed.com/produc ... ring-cover), and then have the cables go from the Vinci stem straight into the headtube tunnel. If the gap between stem and tunnel is only 5 mm or 2 mm then this shouldn't look too bad.

Just looking for any solution that allows using a -17 deg 130 stem with hidden cables on a SystemSix....

Thanks in advance to all who have suggestions.

Hello,

Yes, I was able to install a Deda Vinci stem on my Supersix 2020

You only need to order from Deda the specific Cannondale Supersix spacer compatible with Deda Stem (Deda code: HDVCNTCCANN).

Just one comment: in order, for the moment, not to cut the fork steerer tube, I did not install yet the Deda top cap. It will be nicer and cleaner with it later...

To be able to get full internal routing, I also had to order a FSA K-Force Compact bar (ACR compatible).

I hope it heps...

Thank you so much, prenard. That is very helpful. Now I know you might be the best source for further info. My questions seem long (trying to clarify the details) but the answers can be mostly yes/no:

1. I see you are not using the 5 mm "top aero spacer" that according to the Vinci stem user manual is required right underneath the stem. You have the stem directly on this special Cannondale adapter. As far as you can tell (I know whatever you say is not an official opinion/recommendation) there is no need to put the top spacer in-between stem and adaptor? That Vinci top spacer doesn't have any special shape to acommodate the stem shape or anything like that?

2. As far as you can tell, if you needed to keep your bar as low as possible like me, would you be able to leave out your 4 extra spacers (you have 2 short of 7.5mm + 2 tall of 12.5 mm) and have the special adapter directly on top of the headset/headtube and still apply appropriate bearing preload? In other words, just the stem and the adapter as the only things on the headtube -- you think that works? Given that you have a regular Cannondale spacer immediately on the headset but that spacer would also fit on top of another spacer, the bottom part of the adapter must have the exact same shape and dimensions as the spacer that you use as headset cover I guess....

3. How tall do you estimate the Deda adapter to be? It looks the same height as the 12.5 mm Cannondale spacers, is that correct?

4. Lastly, you say you had to get the FSA bar to get full cable integration. Normally the Deda Vinci bar works perfectly with the Vinci stem. Are you saying there is some reason why the Vinci stem could not be used with a Vinci bar? Or you meantyou had to get FSA as opposed to KNOT or some other non-Deda brand?

Thanks in advance!

Quick answers to some questions:

1. I see you are not using the 5 mm "top aero spacer" that according to the Vinci stem user manual is required right underneath the stem. You have the stem directly on this special Cannondale adapter. As far as you can tell (I know whatever you say is not an official opinion/recommendation) there is no need to put the top spacer in-between stem and adaptor? That Vinci top spacer doesn't have any special shape to acommodate the stem shape or anything like that? => yes, Deda adapter has a special shape to acommodate the stem shape and allow correct cable guidance.

2. As far as you can tell, if you needed to keep your bar as low as possible like me, would you be able to leave out your 4 extra spacers (you have 2 short of 7.5mm + 2 tall of 12.5 mm) and have the special adapter directly on top of the headset/headtube and still apply appropriate bearing preload? In other words, just the stem and the adapter as the only things on the headtube -- you think that works? Given that you have a regular Cannondale spacer immediately on the headset but that spacer would also fit on top of another spacer, the bottom part of the adapter must have the exact same shape and dimensions as the spacer that you use as headset cover I guess.... => You can install special adapter directly on top of the headset/headtube but you have to be aware that it is not as rigid than Cannondale KNOT spacers

3. How tall do you estimate the Deda adapter to be? It looks the same height as the 12.5 mm Cannondale spacers, is that correct? => 16 mm

4. Lastly, you say you had to get the FSA bar to get full cable integration. Normally the Deda Vinci bar works perfectly with the Vinci stem. Are you saying there is some reason why the Vinci stem could not be used with a Vinci bar? Or you meantyou had to get FSA as opposed to KNOT or some other non-Deda brand? => I wanted to use a round bard (not aero). This is why I ised a FSA F-Force bar and not a Deda Vinci bar.

Finnaly, just one remark about frame geometry. You have to know that SS 2020 geometry is a bit different than older SS model. I have a SS 2018 size 60 with a 5 mm spacer and a 6 degrees stem and to get a similar position on SS 2020 with 17 degrees Deda Vinci stem I had to use a lot of KNOT spacers...

I hope it helps...

Thanks again, prenard. I also sent an email to the Deda Elementi technical team and already got the following answers:

They confirmed your points 1 and 2 above that their special Cannondale adapter does not need any other items above or below. It is a headset cover and the stem can go right on top.

Regarding stack height of the special Cannondale adapter, they said 10 mm. Maybe they refer to just the height it actually adds above the headtube whereas maybe you included the lip that goes in front over the Cannondale cable tunnel?

The 2020 SystemSix is the same stack and reach (+/- 2mm) as the 2016 Ridley Noah SL that I ride now with a 130 mm -17 deg stem and only a 5 mm headset cover. Yet "the fastest aero bike in the world" does not allow that same low front end. If the Vinci adds 10 mm under the stem as Deda claims (vs your 16 mm) then that is thelowest possible and still 5 mm higher than my current setup.
