Guys, THIS is the original question, which was answered long ago. The thread has moved onto a disc vs rim brake debate of a type more like those on the A & S forum. As for whether disc brakes are superior, can we just leave it that they have advantages and disadvantages, and people are free to stop their bicycles however they think makes the most sense for them. As far as I'm concerned, I don't care if you choose to use a cinder block on a rope as a brake (no rim or disc wear).

Additionally where if a rim wears out, a new rim has to be bought, and the wheel has to be rebuilt. I would venture that even among posters here few can lace and tension a wheel properly. But--------there is no big deal to replacing a disc or installing pads in disc brake calipers. I would think the ave poster here can do that himself.
And again and the biggest plus for disc brakes is the fact is if a rim cracks, you are on foot. But with disc brakes you can continue to ride with the remaining disc.

As for rebuilding a wheel, you don't necessarily need to relace the wheel. If you have a rim with the same effective rim diameter (ERD), you can tape the new rim onto the old one, detension the spokes, swap the spokes to the new rim one at a time and then retension the wheel. I can, and have, taught many people how to build a wheel from a pile of parts in a couple of hours. There is no magic involved and it's really quite easy to build and tension a wheel.
Changing pads is an entirely different process and has nothing to do with rim wear. Not that changing pads on a set of rim brakes is all that difficult.
Finally, if a rim cracks or a rim is damaged with discs you are still on foot...unless you are planning on cutting the spokes out and riding directly on the disc. I wouldn't suggest that. On the other hand, if you break a brake track on a rim brake, you release the caliper and ride it until you can fix it.
Rydabent, I'm not sure if you got my point from my earlier post or not, but what I was saying is that as a recumbent rider, presumably with smaller diameter wheels, your concerns about brake track wear on rims are valid, but they're also skewed. With a 20" wheel, for example, you will wear out a rim due to brake track wear several times faster than with, say, a 700c rim. I was hoping I could point this out so that some of the posters in the thread, including you, would consider others' perspectives................When we see a 20" wheel on a Bike Friday come in that's got a seriously concaved brake track, we almost always, among ourselves, comment that disc brakes on these bikes would be a good idea. That's not a very common scenario with a "full size" wheel. We see it, but it's not the chronic problem that high mileage riders with smaller wheels are faced with if they're using rim brakes.
) rider would. My wife has a Terry with a 520mm rim on it that is more skittish than my 26" or 700C equipped bikes. She has to brake more often to keep the wheel stable and thus wears the rim faster.

If you want to "argue" the point further, have at it, I've already given way too much time to the matter.

You haven't discovered the quick release lever? "Undoing" the caliper take maybe two seconds if you are slow and deliberate. Reinstalling a disc wheel requires care to assure the disc is aligned with the caliper opening and takes longer than flipping a qr on caliper brakes or disconnecting/connecting the noodle on V-brakes.

From Car Talk:

try bedding in your brakes.
I do it on a steep hill.

I think there may be a language or reading comprehension barrier, and he doesn't know the difference between bedding and bleeding.
