I have a Giant TCR Advanced carbon bike with Giant P-SL1 wheels.
Over the last few rides I have noticed an occasional clicking noise that I thought was coming from my chain. Yesterday, when out on a ride I lost all drive to my rear sprocket. Pedals and sprocket were spinning round but not going anywhere.
I took the wheel off and gave it a tap and got the sprocket to engage but then it wouldnt freewheel. Had to cycle home 12 miles without free wheeling.
Bike is 8 months old and done 900 miles.
Wheel is at my local dealer for warranty repair. I am told it is probably the freehub. How common is this. I looked on the net and found someone with the same problem on the same make and model of wheel.
