I'm 173cm and have a 75cm bb to saddle top, very similar to Howard. I'm a bit more legs than torso. Riding medium arkose with 80mm stem and the fit is great. With 25mm setback Seatpost and stem slammed (well, on to the ~16mm conical headset spacer) I've matched the fit on my size S canyon ultimate (on which is a 110mm stem), albeit with 10mm extra stack, which I think is perfect for the type of bike this is!
I had the same questions as you when buying, and I'm pretty sure either size could work. Not sure if toe overlap is a risk with running the size s.. Worth checking. I ended up with the M simply because that was what was available on ebay at the time of buying. Hope that helps.
True, but when you consider it's likely you'll want to run full guards on the arkose the (potentially non-) issue could become exacerbated no? Especially when climbing/coming to a stop?
