Nope, they are just a a superior brake. And the big thing is they dont scab up expensive rims.

Nah, it's all about centre pull cantis.

The chunks of rim thing is poor brake pad choice. Years ago, I tried Clarks red pads because I couldn't get Kool-Stop salmon. They embedded chips of grit and alloy, and really grooved the rims. The Kool-Stops never do this, being harder - ironically, soft pads punish rims more due to the embedding issue.

RIm brakes are trivial to set up, unless we're talking 1990s cantilevers. Yes, the rims wear out, but if you can replace them yourself it's not a major problem. I commuted on a fixie with only a front brake, so the rim wear issue was just about non-existent, front brakes not being bathed in gritty water.

no they were V brakes, and its the conical/convex washer parts that act as like a socket ball joint, getting those set up properly so the whole pad contacts the rim at the same time flush (maybe with a bit of toe in on the angle so rear contacts fractionally first), its next to impossible to adjust them properly because they are infinitely adjustable and you cant hold them in place locked perfectly and tighten them up properly at the same time.

my disk pads, unscrew one bolt, they pop out, I pop new ones back in theyre already aligned, job done.

and I tried loads of rim brake blocks, largely because in winter I was getting through them so quickly, though you could never buy the same brand/make more than twice before it disappeared from sale. I tried from soft to hard, none of them made a difference, in fact one bike shop told me it was because the rim surface had already worn to an extent so was presenting a rougher surface, and so Id need new wheels to reset it all.

I get people are always going to have debates about this tech and claim theirs is better than yours. but for me theres no debate, disc brakes work for me, are a million times easier to maintain and I wouldnt buy any bike with rim brakes.

This is it 100% rim brakes are as good if not better but they will wear your rims quicker, the point is no pro rider has ever had to worry about rim wear. We’re being forced to buy new bikes for the purpose of new bike sales not because rim brakes are bad.

The manufacturers by not providing rim braked bikes!

Apart from Merida, Giant, Ribble, Genesis...

Although I think I'd be right in saying that @Vapin' Joe means you're not being compelled to buy a new bike, you just want to.

Which is absolutely fine, and sure discs are more prevalent, but it's still pretty easy to get a rim braked bike.

Yes and no.
Rim braked bikes still being made but the choice is dwindling as the years go on. How many manufacturers who still make rim braked bikes offer same spec of bike with option of either rim or disc? I've not checked all models of every manufacturer but I'd be surprised if the range of rim braked bikes is not far far less than of disc.

As I said earlier, my next bike will be discs and I'm happy but I do think the consumer ie us is being given less and less choice which cannot be good.

A very good point. We are all cyclists. We all have bikes. Bikes don't wear out. Just the components. So why go buying new bikes?

Fashion. Lots of very nice rim braked bikes on ebay for not much money.

I bought a £400 wheelset for less than £60 recently including postage - hadn't been used, just stored and the freehub was gunked up with sticky grease. The wheels were for rim brakes.

Unless original been lost/stolen/written off then probably same as all other goods we buy be it a car, tv, whatever it's down to wanting something new and shiny and usually "better". In my case the current bike I have is fine. Carbon, Di2 and everything works as it should. Then wheels are 2nd hand and not great but useable for some time yet. I could buy a new set of rim brake wheels and bike would be for all intents and purposes good as new.

However, I've got the money and I have a yearning for a new bike so I'm intending to buy a new Canyon Endurace as and when (if) they get stock in. I've had current bike for 9 years and definitely got my moneys worth out of it and I intend to keep it for winter. Slightly counter intuitive as new bike will be disc brakes which would be better in the wet but I think I'll attempt to keep new bike shiny as long as possible.
 
Like it or not, disc brakes are now the standard. It is cheaper for mfg to buy one type of brake due to economies of scale. Since the majority of cyclist approve of disc brakes, that is what everyone is going to get.
