Wow, Alot of responses thanks everyone
So I wittled it down to either a 18" or 20", looks like I need to sit on one.
My preference is a smaller frame but the last thing I want to do is buy 2 frames in a row that are too small for me.
NW Alps Jeyer aka Boz – I've sent you an email, thankyou
MrTall – Thanks for your offer also, Will you be riding Clent this weekend?
PaulGillespie – Does an 18" handle ok with a 100mm stem, and as per Tron's advice I have a 225mm steerer tube on my 100mm fork, I left it long so I can be flexible with my riding position.
