I’m trying to reduce weight on my new BMC Roadmachine 01 and first thing to do is swapping handlebar from the 330 gram heavy aluminum branded house brand one.
I’m looking at 3T at the momen. I want to go sub 200 g. Preferably 180 g. Going for size 40.
I could really use some advice here on which one to chose. It must be able to route brake hoses and di2 wires internally.
Is the 3T Ernovo capable of that?
I see some bars have the entry/exit hole placed differently at the lever area. Front or backside of bar.
I am running Shimano Ultegra R8070 levers.

I got the Ernova recently. Seems very nice. Large routing holes and a good amount of flex, which I'm all for as = comfort. CRC have a sick discount on right now - £70 from £199 retail. Came in around 197g.

if the routing is the same as the Ergonova, good luck with the cables.
you're going to need all you can get

Should I rather go for a bar with a cable channel underneath the bar and route hoses there and then only put the wires internally?
What is the struggle with running both hose and di2 wires inside?
Never done this before, that’s why asking.

I don't know what diameter the hoses are, but based on space I have from brake outers there is more than enough for a Di2 cable. Image

If you're happy with your fit have a look at integrated bars perhaps.

They often weigh less and don't have a risk of delaminating at the stem/bar junction. Peace of mind...

Bars with internally routed cables weigh more because they need reinforcement. They have more places where cracks can develop.

Brake hoses seems to be more or less the same diameter as brake cables. Maybe 1mm more.
Integrated bar is not possible with the BMC since it has a fork that is square shaped. Must be run with own BMC integrated stem.
I have in the meantime ordered a 3T Ernova Team Stealth handlebar in 40cm, should tip the scales at 190 g. Super deal at CRC.

Just rode my bike to LBS without any handlebar tape and it already felt a bit different, as in smoother.

As for cracks and delamination. Eh, something to keep an eye on but I'm sure they go through enough fatigue testing that most people don't need to worry.

Also as the holes are on the bottom, I imagine it further reduces risk if damage does occur there.

Congrats on the bars OP, let us know what your impressions are!

EDIT: OP good thing you've got hydraulic hoses and electric cables. Through internal routing shifting suffers quite a lot with mechanical.
