Very well done!

[scottydonald]

I have been searching around all day today for a replacement handleabar for my 2021 Series S.

I originally was all set on the Enve Aero Bar then realised it wont fit.

I have been chatting to Rhino @ryanw on instagram regarding it and he has been tring to help me. I have been chatting to Enve. I have been chatting to Cervelo.

I currently have mechanical Ultegra and patiently waiting for the new DuraAce before i replace it. I wanted to change the hadlebar for a wide aero bar. Seems the key is the hole in the back centre of the bar. Enve told me the AR Road bar has the hole and recomended it but i am not a fan.

Has anyone else found any other options? the Prime bar mentioned before looks promising but is it any good?

I think i have found a new favourite - Vision Metron Aero Handlebar - expensive but really good reviews and a big central hole.

I would ask, apart from weight, what is the problem with the Cervelo bar?, it is aero/teardrop shaped and is super comfortable, the maximum weight you can save by swapping out is around 30g, probably not worth a minimum $200 outlay.

I have ordered the Vision Aero Bar, suggested by Cervelo but they couldnt recomend it as they have not tested it in house.

I wont be able to install it until i get back to Scotland in 3 weeks or so; its my quarantine project!

It was something i didnt like about it since i got the bike, to me it was not full aero but a slight aero bar; the feel of it along with the cervelo tape.

I weigh 98kg and lean so i will not be loosing much weight so the 50g reduction of the new bar wont really make a huge difference. Going to order some Most Superlight Tape to give it a try; annoying there are no real reviews out there on it.

The only bike weight reduction i will get is when i can get the DA 12 speed, that should make a big difference.

So.. I got 'car doored' recently, which resulted in some damage to the bars

Delamination from 2 impact marks


The wahoo mount and saddle also got broken

However, flip side, is I can try out the Prime Primavera Aero 38cm bars with this setup, should save around 35g, I am imagining that this may be a p.i.t.a to thread all the cables through however, wish me luck!

[scottydonald]

Thats really annoying, i have gotten two huge stone chips in the last couple of weeks on my frame.

So i got my Vision Metron Aero handle bar installed in mine - the guy who intstalled it said it was sooo frustrating but got it done in under 2 hours. To me the ride has been so much better since i got it, much prefer the handlebar over the standard Cervelo one.

I just ordered the JL thru axles and now trying to get a lighter cradle.

Once Rhino can get me the New DuraAce in my spec next year then i will go that and some Cermaic Speed goodies for the bike.

The new bars look great scottyd

Finally got around to rebuilding my bike after the car-dooring

The internal cabling was an absolute nightmare to do with such limited space, a few swear words were said!





With Alligator iLinks and the new bars, new weight is 7.08kg

Just need to find somewhere to save 0.8kg

[TourmaletteduFromage]

How is the handlebar? Is the text on the top printed/a sticker?

[stevec1975]

Handlebar is OK, different from the Cervelo one in the drops (it has an ovalised section running for approx 4 inches, which the hands fit into, it's different but I am getting used to it.

The decals are printed on there, the only way to get them off that I can see is to lightly sand them (they are fairly unobtrusive so will just leave them on)

[stevec1975]

oh and in other news. I have Dura Ace 12 Speed to fit.

This will help resolve the spaghetti junction of cables routed through the stem and bars (and be much nicer too)

[scottydonald]

very very jealous.

what setup did you go for your new stuff?

Did you run the ilinks also inside the bars?

[kppolich]

Really nice build and photos.
By chance can you provide more details on the crankset sanding/polishing steps?
If you have any additional pics of that process as well that would be great.

@Scottydonald:

Went for 52/36 - 11:30, selling the cranks and keeping the powermeter with 9100 rings, from what I have seen, they work just as well as the new rings, I think it will be pretty much bang on 7kg with the new bits.

@Pabloldv:

Yes, iLinks inside the bars, unless you have a lot of patience, I would not recommend it, was the hardest cabling job I have ever done, in part, it was the reason why I went Dura Ace 9200, so I could have just the brake hose only in the bars/stem.

@kppolich:

For the sanding, I don't think I have other photos, it literally took 15 mins. Process was: 1, Gaffer Tape the Quarq Spider and Rings. 2, Start with 400, then 600, 800 and a finish with 1000 grit sandpaper, with lots of water, The water should still be mainly white when you are using the final grades. I then use a small amount of T Cut (Car polishing liquid), I haven't touched the cranks since and they are still mirror finish.

Finally got round to putting the DA R9200 stuff on, plus a number of other tweaks and changes.

Super happy with the new weight, finally sub 7 Kg (6.92kg)









Build List: - Lighter blue shaded cells are the changes


Ideally I would like to get this bike UCI illegal (Sub 6.8Kg), so welcome some thoughts on where else to go, things that I have got or I have explored:

• Maxxis High Road SL (saves 118g over the Conti 5000), taking it down to 6.8 on the dot.
• Darimo S3 Seatpost, despite being on the coming soon list, recent convo with them has confirmed this is not coming anytime soon (potential 80g saving)
• THM Clavicula + Speedplay Powrlnk pedals, when available (potential saving 195g)
