I noticed that when going at low speed without pedalling the freewheel sometimes seems to engage anyway and pulling the chain until there is enough tension ( as the rear derailleur contracts due to the chain being pulled ) to overcome it and to let the wheel spin free again.
I also noticed this effect by spinning the cassette by hand with the wheel removed from the bicycle. When spinning it there are points in which it gets stuck and wont let go until I either try to turn it with enough force or I spin it to the opposite direction slightly and then continue. This might happen a couple times per rotation.
I have tried looking for similar problems online but havent been able to find anything, maybe because I'm not sure what to look for as I'm new to biking and I'm trying to learn a bit by repairing this kind of problem my self. I thought of dismounting the cassette and cleaning everything up in case that somehow solves the problem but I wanted to ask first to see if there is any specific solution.
The bicycle is almost new, only having a month or two, so I wouldn't think it has anything to do with wear. Its a Talon 29 1 in case it's of any help.
