Finally stopped procrastinating and completed stage one of the long overdue Great Touring Bike Refurbishment. this was supposed to be swapping the front wheel but it ended up being a bit more involved...
The front wheel was very old; I'd bought is second hand several years ago when it was the best I could afford, and wasn't very good quality to begin with. Since then it had managed several thousand kilometres and was beginning to show it, so about a month ago I bought a new, better quality wheel and tried to fit it.
The Brakes didn't work. It turns out that the bike frame is rather old and designed for cantilever brakes, and the brake bosses (?) were a good 5mm further apart than on newer bikes. The new wheel, by contrast, was about 3mm thinner than the old one, and I'd had to put extra spacers on the brakes to get that to work.
This meant that long term I either had to change to canti brakes, or get a new set of forks. I opted for the forks.
The forks then needed a new crown race, so I ordered that.
On Friday I tried to fit the crown race on the forks; YouTube videos advocate a PVC pipe and a rubber hammer, and then show the mechanic tapping the pipe a couple of times before announcing the crown race was tight. It took a metal pipe and a good ten minutes of pounding with a lump hammer to get mine to fit, maybe German made parts are just more solid. Fortunately I had a metalworker alongside me who assured me this wouldn't damage the crown race; equally fortunately, he was correct.
Yesterday I snuck into work, measured the forks, nervously cut the top off, which turned out to be a lot easier than suggested, and filed it off. To my astonishment not only did the bearing screw on without issue, it also fitted the bike.
After straightening the wheel so the brakes worked, I got on the bike only to hear a "ping, ping, ping" of the spokes settling. I should have expected that.
The bike looks a bit odd with black forks on a red bike but bike-specific paint is on the way so I'll be able to sort that in a few weeks...
