John: My current sprocket has done only 8500km, zero signs of wear, in large part because I take trouble to arrange a perfect 54mm chainline, I have an unused spare as well, and I'm happy with my current setup (44x16T), so I'll wait and see how stressful removing the sprocket lock is time before I decide whether I need the adapter/splined sprocket which will require a whole new engineering job at the front. I rather suspect I'll be the last Rohloffie to give up the threaded sprockets, unless it is you! Also, though I've had a quick look, clearances on my bike are 1mm off the showroom floor -- owners are not encouraged to mess with it! -- so the new chainline may not fit at all.
Martin: Thanks for the check. Seems to me possible, even likely, that an extra 4mm on the chainline will bring the chain uncomfortably close to the paintwork, never mind the Chainglider. But Raven owners will have to check on a bike by bike basis, because we already know that some bikes have clearance and some have less. I suppose it is one of the costs of owning a bike which is properly scaled to size. (Paramount in the States sells a Gunnar which in the larger sizes is grotesquely misproportioned because all rear triangle are the same size no matter how tall the seat tube. It's quite a common costsaving device for designers more interested in profit margins than good bikes.)
