I have some standard XT brakes on my flat bar ‘hybrid’ type bike. I’d like to swap out for some drops, and run some kind of disk braked shifter-hood type roady thing. You can tell the extent of my road knowledge with my termanology.

I have drawn the following conclusions so far.

@ around £350 the combined STI/disc hoods are daft sort of money.
I will need to change rear mech to 11 speed, and cassette too.

Questions:
Can i fit an 11 speed road cassette on my hope pro2’s?

I’m sure i could find all these answers if i was to search really hard, but you guys should know. right?

Thanks muchly in advance.
