I went up a 7-10% climb in the cotswolds on a single speed 42 x 16 today... it wasn't too bad
And yet Campagnolo have already said there will be more cassette options coming later in the year. They’re getting the most popular ones out first.
It’s almost like they’re running a business and trying to make sure the main options are covered at launch.
I get Ugo's point about fragility, I don't have a bottomless pocket and the potential reduction in lifespan of components if I upgrade to 10 speed, never mind 11 or 12 speed is one reason for staying with 9 speed.
sram eagle been out for a while. nothing new there.
