What was/is the reason for this? Electronic shifting? Bigger tires/rims?

I pay attention to "suttle" nuances, - but i must confess, this thread has me at the "braking" point as i may also have to sell all my rim break bicycles Nobody wants a collection of dusty old Euro-trash "10 speedS" anymore

Add in a push for more "aero" frame designs that add material too

I thought it was all about the Indian and not the arrow. Mods, delete it if it's a problem.

This and more targeted stiffness through the BB area etc. Wider rims and tyres a little heavier, especially on the lower tier models. It all adds up, but weight is certainly not everything. Obviously weight is a bit more important on a climbing bike like the Emonda, but serious players will pay extra for the lighter high modulus frame and lighter components. Unless the UCI weight limit drops below the current 6.8 kg there isn't much incentive for manufacturers to make lighter bikes. Having said that Specialized have thrown their hat in the ring with the Aethos at 6 kg (13 lbs) complete with disc brakes and no real compromise like flimsy components.

Read that many will not build rim break bicycles. I love my bikes...feeling sadder older broker...
The simple answer is-----------------if you like them, and they work fine, why get rid of them.

That said, I am on the side of disc brakes, since they dont scab up and wear out rims.

Where are all these worn-out rims of which you speak? In 40 years, some working in bike shops, I have never seen nor even heard of a rim worn out from braking.

Disc brakes? Or your non-riding friends and family?

I volunteer at a big city high-volunteer bike Co-op. We see large volumes of donations come in every week, many of which are wheelsets. Last week we had some Zonda's and some DT Swiss get dropped on us. Of course they were kaput due to rim impacts. We've had Zipp Easton, Mavic and other high-end wheels as well. About once per week a wheel arrives in which the rim braking surface has eroded through due to what obviously was a many years commuting in the rain.

My rough estimate is that we get 10 wheels killed due to impacts for every one in which the rim surface wore through. And of course we get lots of dead wheels due to worn bearings or incompetent maintenance. Actually, I should not say incompetent but more complete lack of maintenance. My assessment is that nobody that comes through our door does any preventative maintenance on their hub/freehubs, and we collectively just let things roll until the bearings are reduced to metal shards and the hubs sound like a coffee grinder. We do get a lot of freewheel type hubs with broken axles - about once per week. Some of these hubs were ridden for weeks in this state, and are then so damaged that they cannot be restored.

So the benefits of disc wheelsets in terms of avoiding worn out rims is greatly overstated. You will hit a big pothole or curb well before rim braking erosion becomes an issue.

Using my Paramount as an example, - the first step is wearing through the anodization like these, --- then more and more aluminum gets abraded away (doesnt happen overnight) until the rim starts getting a concave shape -- at that point its time to lace up a new set of hoops. - This one will never get that far because i hate the way that looks and the bike is largely for display purposes , so it will get swapped out for something pretty though

Have a set of Campagnolo Vento aero wheels from the 90's that i baby along - im suspecting the heat treat on these was bad as they dont have hard miles on them as they were just TT wheels, ---- but the biggest offender for me was front mountain bike wheels before disc brakes --- riding in all conditions with the front brake doing 75% of the work, id get a season out of a rim if i didnt have to re-lace it due to crash damage first

Rim wear is very common in areas that get a lot of salt and sand on the roads duding winter time....All that grit on the roads is extremely abrasive and will wear down rims

Nothin' wrong with wanting new stuff -- especially if you've gotten good use out of the old ones. Tubeless tires, disc brakes, and a dropper post will be revelations!

Thats a nice bike

'02 Litespeed after a (Admittedly pretty expensive but only because i used NOS Campy carbon Record stuff for the majority ) refurb . No - not the absolute most current stuff either, but leaves very little on the table compared to a new bike.

I admit i want some carbon hoops for better bump compliance , but with the limited miles i put on my road stuff, that would be a luxury. That old Bianchi of yours would sing like Luciano Pavarotti with a modern Ultegra refurbishment and a modern stem/bar combo (I wouldnt put anything less than Ultegra or Campy Potenza on a bike like that )

in this day and age that’s a desirable steed — old cyclocross bike with clearance for 34’s is nice!

It's a regional and seasonal thing. Dry-weather bikes most anywhere don't see much rim wear. Wet-weather bikes also can escape most rim wear if the wetness isn't very abrasive, or if there's minimal braking happening. But if the regional gunk is abrasive, and especially if you're riding in the hills or on road networks with a lot of stop-and-go, things can wear pretty fast.

On the Crazy guy on a bike forum, there has been many instances of of worn out rims breaking. They ride rain or shine, and sand and water quickly destroy rims.
