Hi guys and thanks for the feedback. My name is Simon by the way.
I put the RPM app on on my phone and the speeds are as follows:
39.1 (17.1% up)
52.7 (17.1% up)
90.3 (15.8% up) – but dont have or want any 78s so no matter.
I have a new belt that I am yet to fit but cannot see how this would make it go slower?
