Brookbottom, Mellor, Roman Lakes, Brabyns, Chadkirk, Goyt Way, Woodbank Park, Behind British Gas, Reddish Vale, Tesco, quick road spin through Princes St and Heaton Lane, Mersey trail into Manchester. Not much road until you get near the city centre and very nice off road as far as Tesco.
or
all of the above to Reddish Vale then stay on the vale as far as Reddish Vale school, quick scoot from Holdsworth Square to Longford Rd and then get the converted railway line that goes up to Sports City and then a very small bit of canal from MCFC into the city centre or go left before Gorton on the cycle path into Rusholme. This route is very little road all the way.
I do Offerton Green to Manchester each day. I prefer the road route through Cheadle, Didsbury and rusholme but do the latter of the off road routes above once or twice a week. Usually coming home.
