Looking at buying a Camber 29 frame, I am always in the middle of sizes at 5' 11 n a bit inches with a 31.5" inside leg. Currently ride a 46cm (medium) Lapierre 29er and a 19" Large Marin full suss which has always niggled at me as being a bit long.
What sizes are you riding please for real world views. I know size chart has me as a large. At a push I can go find a dealer with one, but order is online.
