I’m looking for a good carbon aero bar for my 2019 Scott Foil 10 with Ultegra Di2.
Stem is the Syncros RR1.0 Aero Foil stem.
I need to be able to integrate the junction box into the drops of the bar, which eliminates a few bars, from what I can tell.
Reach should be compact, which eliminates the 3T Aeronova.
I know there is the Syncros integrated cockpit, which my bike doesn’t have - but it’s expensive, I can’t find any good deals right now and I’m not sure if I really like it.
I like the looks of the Enve Aero Bar - but only the newer version is Di2-compatible (can anyone confirm this?) and it’s not the lightest option. It’s also too expensive new.
Then there’s also the Pro Vibe Aero - which I don’t find super pretty.
Specialized Aerofly II is one of my favorite bars. It’s $300. My 44cm weighed 237g. I did the Di2 bar end junction with them. And if you do want the Syncros bar, Competitive Cyclist has it for $400, but you can get 20% off as a new customer if you sign up for the newsletter. Which would bring it down to $320. Enve is another choice but at $400 it’s expensive.
I do not have Di2 so can’t help there but I have owned the 3T Aeronova LTD Bars. Specs: 31.8mm/400mm/104mm Reach/127mm Drop/ Weight 205g (my scale). I recently switched to the Vibe Aero Superlight 31.8mm/380mm/80mm Reach/ 130mm Drop/ Weight 205g (my scale).
The internal routing is very similar on both bars, the Vibes match very well with the Pro Vibe stem. The 3Ts reach is definitely something to consider and they had more flex compared to the Vibes. I haven’t had a chance to ride much with the Vibes but so far seems like a great bar and are specifically made for Di2 especially when matched with the Pro Vibe stem.
Check the Prime Primavera at Wiggle/Chain Reaction. It’s fairly cheap for a carbon aerobar. The cable holes to run internal cables are huge, and it has drillings near the end of the drops (I assume for Di2 wires). CRC had it is a 38cm width too. Also plenty of room for a handlebar mount/clip ons (assuming compatibility).
Ritchey and Deda both have bars with aero tops that are compatible with the bar end junction. The Ritchey is more compact, IIRC the Deda bar has a tad more (5mm?) of reach and just slightly more drop. Also you have to be careful shopping for that Deda bar as I believe there was an older version that looked like it but didn’t have all the holes or maybe the bar end didn’t fit, I’m not sure.
