God knows why.



Maybe a bit of nostalgia but most of all I do not like to ditch stuff
that is still perfectly working. Just like a former colleague who used a
1954 Chevy pickup truck as his daily driver. On days when he didn't have
anything to pick up from Home Depot he often used their early 50's Chevy
Bel Air. Both surprisingly low maintenance.


I've got to think a 1950s Chevy needs a LOT of maintenance compared with
a modern car.

I've kept the maintenance log notebooks from almost every vehicle I
owned. The ones I had in the 1970s seemed pretty good to me at the time.
But when I resurrected their notebooks out of curiosity (Kawasaki
motorcycle, Corvair Corsa, Honda Civic) I was astonished at how often I
was fixing things.

My point is that low gears and fat tires make for a more versatile bike -- and those are two things you can't get on your current bike. You'll never be able to use a 30mm tire,


I wonder if that's really true. That 1972 Raleigh I still use for some
rides has 32mm (AKA 1 1/4") tires on it right now, with no problems.


That's the difference in ten years and perhaps brands. Joerg is stuck at 25mm -- or at least that's what he's running. The bike is sized for 49mm drop caliper, if I'm reading his posts correctly. That might get you a 28mm, but probably not.

Not to mention the expected routine maintenance: Points, plugs, check
ignition timing and dwell, valve lash, lubricate dozens of thirsty
little zerk fittings ...

6000 burnt residence, whatever was in them. Very weird smell.


On Sunday I rode pretty hard for an hour with a disposable N95 mask.
I was surprised how well the mask worked overall, both in letting me
breathe, even when climbing, and in filtering. When I adjusted it or
raised it to spit, all of a sudden my attention was drawn back to how
smoky the air smelled.

The exhale vent proves vital once the respiration rate increases.

Yes, the Goat/Roadlink add that same down-and-back placement that
lets the newer derailers take up chain from a 51t cog. They seem to
have some very good engineers over at Wolf Tooth; the company makes
quite a few very interesting "Problem Solvers", ahem. Good hacks!

Joerg in particular might enjoy their B-Rad system (except that it
won't fit his favorite growler).

Thanks, it's entered into the wish list in my bike wiki file.

I was thinking about getting a N95 or P100 mask but the next Home Depot
is a few hills and slightly over an hour riding from here, with the
valley sections smoke-filled. So I didn't go.

Yesterday I ordered a Sunrace 11-40T cassette, a derailer extender thing
and a MicroShift long cage derailer. After that gets here I'll probably
start breaking more spokes on the rear wheel :-)

I'll try to resist the temptation to do low speed wheelies.

I can't because my MTB doesn't even have the space for a single water
bottle of decent size. Even the bike dealer where I bought is said
"WHAT?? How could they now have that?". So I mounted one holder on the
handlebar (I have a bike with a cup holder now!) plus modded the rear
section for some heavy duty longhaul schlepping.

I've seen several ingenious ways of carrying water bottles, even on
frames like yours. But I'm pretty sure they wouldn't work for you.

Why? On 25C road tires, you will either lose traction or pop a wheelie before you can apply full torque, and even applying full torque, you shouldn't be breaking spokes. Do you break spokes on your mountain bike? If so, I think you need a better wheel builder. I didn't break spokes on my tandem with maybe 340lb total load and a triple. The rear wheel was a meager 40 14/15g spokes.

I don't sweat it anymore because the rim is going to be up soon anyhow.
I am keeping an eye out for the Vuelta set you recommended a while ago,
to catch it when it goes on sale.

The main reason for mounting a 40T cog and probably also the 36T next to
it is so I don't have to mash up hills anymore but I'll do my best to
refrain from "putting on the coals" on the uphill in that low gear.
