Rim Brake Bikes Banned from the Stelvio

Band of Climbers has this morning learned that bikes with rim brakes are to be completely banned from the Passo dello Stelvio. The new rule, which comes in place as of today, means only those riders with disc brake bikes are allowed to climb, and crucially descend Italy's most famous mountain...

I should probably change my sig today. Or ...not

Well, a rim brake actually is a disc brake of sorts......

Chris Froome once again derides disc brakes on road bikes

Froome points out rubbing and alignment issues on the last-generation Shimano 9170 disc brakes

I can't blame him.

I spent half a month this winter ruing the decision to use disc brakes on those days at those times.

Rim brakes, what are those? Oh yeah, I see all the old timers with those on their velocipedes...

Rubbing Shimano discs are the least of the Peloton's issue with Shimano right now.

I am not a disc brake doubter. Have had them on the MTB forever and more recently on the road bike, and would not go back.

However, Froome does make a good point about the pad retraction thing. They always seem so lazy and inconsistent (left vs. right). Have never really understood why that is such a sticking point (sorry). For one thing, why are the springs that push the pads back into the calipers so weak?

Yah, this guy is ANCIENT! Remember way back when this happened??

F*ck if I know. That was not a joke or hyperbole above - on 15 of ~80 ride days Jan-Mar of 2022 I lost discs either because they wouldn't retract and I had to ride/glaze them out of lockup to get home, or they simply stuck partway closed.

The ancient Weinmann center pulls with Kool Stop pads were more reliable and therefore more effective.

Been riding disc only for 5 years now under all conditions, never had more than some minor rub. I've had to prise the pads open once or twice because yours truly accidentally pulled the left brake handle with the rim off. I have more problems with tubeless systems. YMMV?

I am reminded why I never invested in CF rims with the fancy brake tracks. I met a chap from NZ that was visiting town. He had brought his bike with him and it had a nice set of Zipp CF rims. On the descent on Mount Soledad, his brake track heated up sufficiently to cause serious warping. He was riding another day or two so I loaned him a front wheel for his remaining rides.

I have no experience with road bike discs, but on mtb there's actually pretty big difference between different manufacturers. While there was simply no way to get my old Formula R1 (not really cheapest thing) brakes and discs to run without rubbing (for me it was more problem annoying noise this rubbing made then power loss), I have absolutely no issues with Shimano XT brakes. They might develop small rubbing after long descent when they heat up, but after 15 or 20sec they are all good and all rubbing is gone. I don't know what difference it really matters, as I have different brakes and different discs, but I would actually say it's discs that matter more then brake calipers, but I'm nowhere near to be sure. I currently use Shimano discs, which are steel/alu/steel sandwich, so this might make difference compared to discs I used on rubbing Formula R1, and were full steel discs.

I had the R1 on a bike for a long time (7 years?) and never had an issue. I think you're right about the rotors, and I think you might somehow have ended up with the wrong ones. The reason I say this is that I never had success with off the shelf replacement rotors. Shop said they were too thick. I didn't have a good pair of measuring calipers at the time, so I take their word for it. But the OEM ones worked fine.
