ok

Yup

Chain is the same. The wear is in the rollers/pins and they are all the same there.
Cassette wear is different.

The desktop version gives you a bit more flexibility. I've encountered quirks adding new gear from the mobile app where it removes other defaults I have set for gear of the same category.

This is what I do: Add the chain as a piece of gear in the "other" category. Then set the max distance for how far you want to ride between oil changes, or cleaning and re-lubing the chain. Once you get to that distance and service the chain reset the max distance to add an additional X # of miles to the max distance. That way you can keep up with your maintenance schedule and total distance on the chain. Anyone have a better way that they do it or tweeks that I can use?

When you make a chain, you can increase its durability by using harder steel than before or by widening the chain. The amount of pressure at a given point is tension divided by surface area, so you have to either reduce tension or increase surface area to improve durability.

So in theory, chains for more speeds -- which are narrower -- should last shorter. Do they in practice? I don't know. I know that derailleur chains (3/32" wide) last shorter than one-speed chains (1/8" wide), but width is one reason, and lack of shifting is another, and I don't know how much each of these reasons weigh in. And one-speed chains are the same as are used on bikes with internally geared hubs.

I've never worn out a chainring, and I've worn out freewheels and cassette cogs only rarely. I manage to do that by replacing my chain frequently, perhaps even before it is officially worn. It's easier for me, and I believe it is more economical than replacing cassettes and chainrings.

Replacing a chain at 1,500 miles?

Why bother cleaning and lubing at that rate...

I do minimal cleaning. If it gets grimy and cleaning would be a chore, I replace the chain. You could argue it's wasteful, but I'm economical with everything else in my life, and I consider it my indulgence. This approach saves me work, dirt, and components.

I was referring to howheels' post that mentions meticulous cleaning & lubing, and also replacing frequently.

Your strategy makes sense, but then you also miss out on the great chain-cleaning debate.

I use wax to lube my chains, have no dirt to deal with. Actually wax with graphite powder. (I think the stuff that comes on new chains is a mess) When it squeaks, I just heat it in the oven and rub a bit more wax on. Happens about every 7-800 miles.
On another tack, how about if we say chains elongate, or lengthen. I mean, really, everyone knows what we mean when we say chains stretch!

Because I like a clean chain that doesn't make noise. It also makes a good opportunity to inspect other components of my drivetrain.

Because after 200-300 miles a lubed chain is lower friction.

Entering components into my Strava profile every time I change them isn't really worth the effort. But sure, that's a way to track it with some accuracy.

This. SRAM ring new take offs, $50. 5800 Cassette $35, HG600 chain $15. Not riding in the rain helps a lot.

Modern bikes have awesome durability and internet wisdom means everyone knows the best way to maintain their gear.

Yeah, selecting the particular bike that I rode on is about as much detail as I want to go in to on Strava.

I ride Dura-Ace, and I don't worry about wear and replacement costs either.

No problem.

I ride 105 because I'm too lazy to take the DA out of the drawer and put it on my bike.
But, I agree, No problem.

My 11 speed chains last 1-2,000 miles longer than my 10 speed.

Shimano claims the new 11 speed DA chain is Teflon (PTFE) coated and wears 20% better than 10 speed.

I honestly NEVER knew that. Learn new things daily...Thanks!

Same. Cassette might be less with 11 speed. Hard to tell, but it is thinner.

That is an overall equipment improvement having nothing to do with being 10 or 11.

I use 105 chains, because I have never been able to discern any difference (other than a few grams of weight).

The more narrow chains use a higher quality metal in their side plates as precision of shifts is critical for performance. With that, the more narrow chains today are better than an older 6 or 7 speed Sedis chain (sp?).

Some posted that they get 1500 miles per chain. That sounds really low to me.

+1

It sounds like the wear you would get if you replaced it when a chain checker device says it is worn out.
