I've just seen the Factor Ostro Gravel and the Basso Diamante 2023. Ostro is cool, just what every Fred dreams of, an integrated aero melt with gravel tires. Seriously though, aero gravel, who goes that fast on gravel.
The new diamante on the other hand WOW, so light, so aggressive, like the modern supersix should have been. Internet pics don't do much justice but pending a test ride my favorite modern bike.
