I have a GT Aggressor 1.0
Recently on a long ride, the crank started to roll freely after a long downhill. i.e. when pedaling, the cycled does not move because the rear freewheel simply rolled freely without engaging. I think the problem is with the rear hub which may need to be replaced.
From looking at the specs, the hub is a "Alloy Cassette Disc QR". Trying to find it at amazon.com, there were so many to chose from and did not know which one to purchase to replace this.
Any advice is much appreciated.
