Hi I have a Flow pump with mechanical shifting , it intermittently stops shifting.
On the hydraulic shift tubes one side gets hot the other is much cooler

if some one has a flow pump can they please advise are the tubes hot or cold , this way i can work out which side is faulty

Those shift tubes and springs need to be replaced, they can get worn out and that can cause erratic shifting.
