Mostly the luggage on my Dave Yates, which looks proper set up now. I added an extra bottle cage under the downtube for tools, as the saddlebag I'm using makes them a bit inaccessible (and the gigantic Carradice+support was really bloody heavy). This was a bit of a bodge, as one of the Zefal thinagamibobs snapped, and I replaced it with a cable tie. Best not to ask how, but I've given it a thrash around some local offroad tracks, and nothing came pinging off. Worst-case scenario, I reckon, is I boot my tools down the road.
While I was at it, I re-mounted the Zefal Hpx under the top tube using an old Topeak mount, as the Zefal is a bit short to fit inside the frame, and my previous solution of a reusable cable tie and a toestrap was a right faff.
However, the main job (after building a new rear wheel last week, that is) was fitting one of my B17s. I think the B17N experiment is over, I never was that comfortable on the thing, and I can ride for miles on a B17 with or without special clothing. Since I'm currently N-1 until I buy a Disc Trucker, the saddle was going spare, so it'd be daft not to use it.
I just need to keep an eye on the rear tyre for this weekend's 600. I suspect I might replace it, as it looks a little worn, and the new rim is one of the super-tight Chrinas (I broke two tyre levers on it last week, one getting the tyre on and one getting it off again when I had a puncture - at least it reassured me that I could fix a puncture in the wild, though I may carry a metal tyre lever just to be sure). Mind you, there's a bit of space in the rear triangle, maybes I'll put a spare tyre in there.
