Recently my ACS freewheel has become slightly less easier to rotate, like when i push the bike along, the cranks now spin aswell since the freewheel is sticking a bit. Its not much, just a bit annoying......
Im assuming that its because theres some dirt in my freewheel, but will it actually affect the performance of it? Because i really dont want to go to the effort of cleaning it out if i don't really need to?
Thanks
