ok went and sat on the 18" and felt it a bit small ( I`m 6ft ) so tried the 20", felt better but maybe a smidgen too big :S no 19" which is a pity. Guy in Halfords was very helpful indeed suggested a shorter stem, though I didn`t feel stretched just thinking about off road. Had just about an 1" of hee haw clearance on top tube. So have reserved the 20" just now and hes gonna keep his eyes peeled for anything else that comes up. BTW missed out on a voodoo boker ( ok a 2008 model ) but far far better spec than anything else for £400!!
Hmm might go back in and check sizes again ......
