Hello,

I’m thinking about chancing my crosser from a 2x 10 to a 2x 9.
Now I am using ultegra 10spd and I’m thinking about 9spd dura ace.
Can u guys tell me why I shouldn’t do it?
It will save me (student) a lot of money on chains and cassette’s…
Can I use my 10spd rear and front derailleur?

Gr kees

For compatibility check the shimano website:

you have to buy new shifters.

for the price of them you can buya lot of chains


ride cheaper cassettes and chaines like
shimano 105,so you can save money
