Hi
I need to change cassette on my bike and not having done this before I thought I’d ask for advice as I am sure there is plenty of experience there that I could use.
I ordered new cassette and chain so I will change both but do I also need to change the pulleys on rear derailleur?
Also, when fitting the new cassette, how important is to use torque wrench to achieve 40Nm or can I just carefully tighten cassette with hand?
Any advice will be much appreciated.
Thanks!
