Well I've been out on it and . . . . . .WHAT A BLAST !!!!!
Chose an area that I'm familliar with to settle things in
Plenty of singletrack
I'm not worried about getting it dirty
Even collected some shrubbery
The only issues I had was with a worn front mech not going in to granny ring (have now fitted a less worn mech) and the saddle clamp settling down on the seat post (took a multi tool with me so delt with that there and then).
