However I don’t rule out the Mercury developing its spec to become my one all rounder. We shall see!
Be interesting to see where you go with this, bars, brake and usage.
Some people have successfully specified and used Mercurys as all rounders, it doesn't work for me. It suits me for a quite narrow band of my cycling, happily the cycling I enjoy the most, and the Mercury has been the best bike I've owned for it, but it's never felt like the general purpose bike it's predecessor was. It hasn't been my most used bike, and now I have a Nomad to go with it, it's likely to be used less.
You didn't need a decal to tell if it was an 853 fork, it's the only V brake version that doesn't have any fittings for luggage. The decal on my fork is an ugly black one, rather than the usual green, I'm tempted to remove it as it's over the lacquer, I think on the original forks it was under, as it is on the frame. But then no one would know it was 853... vanity, vanity (Not that anyone notices anyway!) Regardless of stickers, it is IMO an excellent fork.
