This is usually caused by corrosion in the small bit of cable which enters the Rear Der. The loop there makes this vulnerable to hanging up and preventing the RD from reverting to the default position on the smallest sprocket. Best to dismantle the cable and replace or as a bodge, pull outer from the cable-stops, releasing the outer, slide the outer along the now slack cable and lube the inner with lightgrease and the outer with oil. The cable when replaced in the cable-stops, should not need adjusting but a proper job may mean replacing the outer and inner cables.

Thanks for advice will read the parktool site . Thanks onbike but the bike is only 6 weeks old so don/t think it will be corrosion.

probably just the cable "bedding in" abit, just increase the tension slightly see how it goes.

Think your probably right ant will see how it goes.
