I sent this to 50Cycles but still they haven't even had the courtesy to acknowledge the email never mind answer it;-bump, - can anybody help with this, as I've emailed and called 50cycles twice, once yesterday and once today, but they appear to be a bit busy.
I really want to go and try and get a tyre at lunchtime
cheers

"I received my order and have fitted all the parts, but I noticed a big difference between the old large drive sprocket teeth (pedal end) and the new one. They are a different shape! Is that new shape of teeth OK as I am getting some noise especially on the downward stroke of the left pedal and I am now wondering if that is the wrong chain sprocket."
