I have a small issue which I would like some help from those that are in the know on the hub. I have two sets of wheels, one Novatec sprint (2012) and one Giant PR2 (Standard on a giant TCR 2(2012). They both have shimano 28-11 cassettes on. one is 105 and the other is Ultegra. When I switch between the two I have to either tighten the tension or loosen the rear mech depending on which wheel I have changed from. I am a little confused as for the need to adjust the mech, I dont touch the limits only the barrel. Is it in my mind or is there a difference on the free hubs? Thanks in advance. (I have attached a picture of the Novatec rims in question, because I think all threads need pictures )
