Not sure how popular Orbea bikes is among this community (I am about to get a MYO Orbea Orca Aero in a few weeks) but looks like Orbea is releasing a new Orbea Orca (their lightweight racing road bike frame) this week on July 20.
The teaser photo on their Strava Club post has the weight of the bike (or just frame?) at 6.64 kg. Will need to read the fine print on what that 6.64 kg includes but looks promising.
Edit: Hard to tell with these blurry, teaser photos but that top tube looks thin
I just bought a used Orca, 2018 model, orange, Ultegra Mech for a bargain and I quite like it. If it wasn’t for that I would be as interested. Seems like a decent price for the 105Di2 - as far as my wallet is concerned at least.
