Some sort of animal fighting/death noises woke me up early this morning, so here I am, with some spare time to blog.

Yesterday morning, scrottie suggested that I go ahead and put new brake pads on the Jolly Roger already, since I have been complaining that the prior ones have worn out, what with the hills and weather around here. As I was cleaning the rims a bit, I noticed this:

Cracked rim

Cracked rim.

That meant that a trip to the bike shop suddenly looked like a good idea.

It also seemed like a good idea to clean my drivetrain, while I was at it, which led me to discover this:

Used to go all the way to 11

One of the fancy, 11-tooth rear derailleur cogs has worn through.

The cogs were an entertaining experiment, but I'm concluding they aren't worth it. The extra holes are just extra places where grime can accumulate and accelerate the wear-and-tear. For now I've put on the replacement derailleur I bought a year or three ago, and shifting is vastly improved. I should probably keep this derailleur anyway and get fresh cogs for it. Maybe clean it up a little.

Between the derailleur replacement and some front derailleur adjustments, shifting is now vastly improved.

scrottie rode the tallbike while we did errands, which meant delays at a couple of stops while chatting with various people. At the bike shop, in addition to ordering a replacement wheel, I purchased a crank puller and bottom bracket spline tool, and also ordered a wheel truing stand. The truing stand is something of an overdue purchase.

The bike mechanics at Blue Heron didn't think it would be all that worthwhile to rebuild the existing wheel with a new rim, but I might try it anyway as a way of learning how to build wheels. We'll see.


The other major project for the day was Fleamageddon. In her adventures outside, miss Emma has picked up a case of the fleas. A month ago, I dosed her with lufenuron, but that hasn't quite done the trick, so yesterday we gave her a 24-hour dose of nitenpyram and commenced with the washing of everything and diatomaceous-earthing of everything else. I kind of hate having to resort to chemical warfare to eradicate the fleas.

Emma's fancy new scratching post and perch has also arrived, so we assembled it, too. It was like putting together Ikea furniture, but I am pleased by the surface area for sharpening her claws. Hopefully Emma agrees.

a well worn title!

Wowie I have never seen a worn-through jockey pulley before.
I bought some of the aluminum with ceramic bearings jockey pulleys, which will presumably last the rest of my life. Total overkill.
What brand of rim was it, that cracked?

Yeah, that is not the spot where I was expecting those pulleys to fail! Back when I discovered the prior pulleys failing, I bought an entire new Shimano Mega 9-Speed rear derailleur, so that's on there now. The prior set of pulleys lasted me at least 6 or 7 years. Shrug.

The rims were 36-spoke Mavic XC717's, purchased in early 2011. I think I've put in ~4000 miles/year on the Jolly Roger, so that's 20,000 miles before failure. Keep in mind that a lot of those miles were on Texas chipseal, and I am often carrying a heavy backpack + pannier with tools in it <-- probably what caused seat rail failure.

The shop where I ordered the replacement wheel suggested Velocity NoBS, so that's what I'll try next.

I hadn't thought about increased weight, but yeah that makes sense. Still, that's a scary quick failure, from my perspective.

Scary quick for the wheel, or the derailleur pulleys?

The wheel seemed pretty fast to me, especially given that I had aimed for a wheel that would last a long time. Then again, the mechanic pointed out that the braking surface felt pretty worn, too. Altogether it has kept high spoke tension very well over its lifespan. I am thinking about shopping for a replacement rim and learning about wheel-building with the hub and spokes, which I think still have a good bit of life left to them.

If I'm remembering correctly, it's the third wheel I've put on the Jolly Roger. The first and second were fairly cheap aluminum things that wore out at the hub.

Yeah, fast for the wheel. If you're even a little interested in wheel-building see if you can find a decent copy of Jobst Brandt's "The Bicycle Wheel". He was a very odd guy but he wrote a pretty good book that would cover your use cases. (no patience at all with disc or composite-spoke wheels.)
Hub, yes. I'm reluctant to reuse spokes, because they're inexpensive and kind of a PITA to reuse, primarily because if it was an outside-flange spoke and gets turned into an inside-flange spoke, or vice versa, they seem to fail a lot more quickly than a new spoke.
Jun. 8th, 2016 04:43 pm (UTC)
Hmm, so if I reuse the spokes, maybe I should label them all so they wind up in the same position, heh. I'd heard about The Bicycle Wheel and was figuring I'd want to pick it up while pursuing this route. I have this feeling that wheel-building could appeal to my anal-retentive side. :^)

It is meditative and very enjoyable, in my opinion. You can do it on the bike, using the brakes as guides, but a truing stand does make it significantly easier.
