Rainy day, so had a look at a few things on the tandem post tour.
Everything is always much more difficult than it should be!
First up, pads needed replacing front and rear. Took the opportunity to just slightly move the rear rack which allows much easier access to the pad adjustment.
Naturally, the calipers needed realigning too, and naturally it turned out I hadn't quite seated the rear wheel properly, so had to do it again...
Next up, took the rear wheel off to have a look at cassette removal. When we acquired the tandem mid- tour it was a total pita, and wanted to make sure I could do it now in the comfort of our garage, and also test out the cheapo tools acquired for the job for touring. Turned out worse this time.
First, the disc rotor was cracked! This is the worst, but there were 3 others at the same points on the rim
No idea how common this sort of failure is. The disc is still thicker than its stated 1.5mm minimum. Anyway, I'd in my paranoia carried a spare rotor for the whole tour, so fitted that, although managed to round off a hex bolt in the process.
Now onto cassette removal. It's a Hope hub, and last time, trying to prise off the cassette resulted in the hub coming apart. Same again this time - a nice education in engineering design of the internals, but a crap design IMHO. That's the pawls you can see as the freehub has come away with the cassette. It's just pushed on, nothing to hold it. And yes, I did manage not to lose the 4th pawl, thankfully.
Finally, after judicious use of the hammer, managed to free the cassette from the freehub. The freehub is aluminium (crap choice IMO) and gouged to shoot, hence the difficulty removing.
Also, it wasn't easy getting it back together again either, there's that green elastomer seal which doesn't like seating. Again, a crappy design IMHO, but at least I know what I'm doing now. Chain and cassette do need replacing, but that can wait wheel rebuild. I'm now tempted by a completely new wheelset given the hub issues.
Then gears; we've had a bit of difficulty getting adjusted for both big and little chainring simultaneously. Lowered the front derailleur by a quarter of a nadge, which seems to have sorted it.
Finally, trying to fight the inevitable creaks, tried to take front cranks off to grease the taper. Found it difficult to get the removal tool to take on first side but got there in the end. Other side, failed completely, will have to take to LBS.
I do Hope (see what I did there?) this was as tedious for you to read as it was for me to do!
