do you really think the 'New Stuff' is any faster?
brakes are about 'slower' - best never to use brakes unless really necessary... LOL!
If I still lived in Sussex Cty, I;d own ONE disc bike (prolly gravel...) to ride on those really rainy days... Wet roads from a recent shower don;t count...
You have a current CF or Ti rim brake road bike from the mid to later 2010s with great wheels, you have the fastest machine out there.
Ride it hard, treasure it.
Guts, not bling, gets you down the road...
Ride On
