It seems as though the tipping point has been reached. Road disc is not just an option, very shortly it will be the only option for a high-end bike, relegating rim brakes to the bike path. With Campagnolo launching its road disc brake components, H 11, every major component group manufacturer has an attractive disc braking option. For all those disc brake deniers out there, just remember, every argument being made against disc has already been made, over 10 years ago, when mountain bikes went disc. We don’t see any serious rim brake mountain bikes anymore, and we won’t see any serious rim braking road bikes in five years time.

What an ignorant comment from Peloton.

Equally ignorant would be deny that disc brakes have some advantages

The dis-advantages for road are distinct from MTB requirements, namely a premium on weight and aerodynamics

Up to the end user whether those drawbacks are outweighed by superior stopping power

Just to be clear - although that quote was attributed to me (I don't agree with it at all) it was a partial quote taken from when I posted the Entire cached Peloton article that was taken down as they released the info too soon.

However I have seen enough stuff that it sounds like the Aero Penalty is minimal at worst and with good design can be mostly if not fully negated.

I've had enough Disc bikes now - starting with with Avid Mech's 12 years ago - to RS685's and now on SR with Spyre's on my gravel bike that I'm really not a fan - due to the noise issues. They all make a great racket at points - especially when wet or dirty.

That being said Campy Carbon rims with Campy pads make noise as well (although they do work quite well).

The part about the new Campy Brakes that has me very intrigued about is the supposedly lack of noise.

I'm still just P*ssed about the lack of Post Mount.

I've been in touch with Hope and they are going to Test their RX4's with Campy levers, and Magura Calipers use the same fluid as Campy (and they make the Campy Calipers and Hydro Parts in the levers) so I would guess they would work.

Let's just hope Campy will sell the levers separately like Shimano does.

As far as I know there is some aero penalty, which might be small but it's there, and of course a weight penalty, which as things stand isn't small in the context of the weights obsessed about on here.

Campy pads on campy rims I ride everyday and like the sound. It's aeronautical at worst ...

Calnago wrote:Have Campy's red pads for carbon rims changed in the last year? If so, I hadn't noticed. They have always been superb imo and I too like the sound they make. I wonder if it's due to the cutouts. I have a set of the red pads for Shimano 9100 brake shoes that I'll be trying out shortly, and the cutouts are somewhat different. I'll be able to compare the difference using the same rims (Boras).

Calnago wrote:Yes, and I have a set of Magura Hydraulic rim brakes coupled with their hydraulic road levers (HS77) made for only one season I think but never took off since they weren't compatible with ergo/sti shifters, so you had to use either downtube shifters or bar ends. Great brakes. But now, things have changed and they can mix hydraulics with the shifters. Therefore I see no reason that nice hydraulic rim calipers for road bikes couldn't be the ultimate goto option over discs on high end road bikes. Unless you want to run huge tires, are there really any advantages to discs on a road bike? Versus a nice set of hydraulic rim calipers? The ease of action and modulation comes from the hydraulics, not the discs themselves. A road bike is rarely if ever subjected to mud deeper than the rim profile, in which case yes, discs are preferable hence they are on mountain bikes. So, unless you want to run huge tires on your road bike, like 30+ mm and clearance becomes an issue, I would totally opt for hydraulic rim calipers with some nice levers to match. No extended chainstays to mess up the tight road bike handling characteristics we've come to enjoy. No frame beefing up. No wheel beefing up. Same ol, same ol, except for the added light action of the rim brakes being activated hydraulically rather than via a cable. Oh yeah, and a little less of that thing we refer to here as weight. But who cares about weight, right?

Of course, this would mean that the sea change of new frames etc., and the obsolescence of all existing road bikes would not happen, and I could see that as being frowned upon by the manufacturers who are licking their financial chops at the prospects here.

So come on Magura, and any other brake manufacturers that see this as a huge opportunity. Bring it!

If they're significantly better than the old ones they must be incredible. I did thousands of miles on the set that came with my Record brakes about 5 years ago and they still looked brand new when I got rid of that bike. By comparison the SRAM (by Swissstop) black pads that came with the Red brakes on the next bike were less powerful, more spongy, more grabby, more noisy and wore at least 3 or 4 times faster, all on the same set of wheels.
