done Lee on my 100mm travel hardtail, no problems, definately more fun with added bounce though
Would recommend though if its a windy blustery day maybe consider somewhere else, it gets quite exposed up there and a long way to go just to get battered by the wind
Cannock green trail is very family trail, and passes some nice parts of the chase, plenty of cheeky tracks leaving off it too if you went for an explore and caught your missus back up
Having said that follow the dog trail at cannock is a very easy red, prob in line with blues at places like Glentress, she should manage that no problems. Monkey Trail is much more technical
