Walker was using a white indutries freewheel at the worlds last weekend,but has used shimano ones previoulsy when hes been waiting for a wheel build etc.
To be honest i dont think there worth the money they cost,i had one on for a couple of months and yeah the pick up is ace but they skip too much....And then my pawls started snapping it was just a nightmare,there when we came to take it of the crank arm it wouldnt even come of...Not even mr waynio and mr akrigg could get if off.
