As title really. I am debating whether to go ten speed for my new project. Have had 9 speed on the old one and it has been bomb proof despite a pretty neglectful cleaning schedule.
Was going to go 9 speed but don't want the shifter windows on the tiagra shifters and was considering a mixture of tiagra 10speed and 105 shifters.
What is the longevity of 10 speed stuff like? Or am I better off with the older 9 speed stuff which I know to be very tough?
Thnks for your thoughts.
