Yup, I think I will get one, maybe two more chains out of my current drivetrain. Mechs looking beat and shifter is about 6 years old so all getting a bit tired!
Im in the happy position of getting stuff at trade price and I do enjoy shiny things.
At the moment Im swaying toward waiting as long as possible to see what new stuff is released. Bikes are getting like laptops/phones now, its out of date if its a year old!
