I'll try this tomorrow after work. As I'm a noob to these tensioners, which is the pinch bolt you are referring to please.
Also it's recommended not to use a quick link for trials for obvious reasons so by removing the quick link it will in turn make the chain tighter.
It's a KMC chain at present, if using a quick link is frowned upon then why are the Inspired bikes sent out to customers with the quick link attached .
