"you'll never see the major manufacturers doing disc brakes on road bikes!!" LOL!

http://cyclingtips.com.au/2015/08/eight-worldtour-teams-to-begin-using-disc-brakes-in-the-peloton-this-month-mass-rollout-likely-in-2016/

That said, I hope the trend of discs on the road eventually just leads to hydraulic rim calipers. We'll see....

CK, why would rim hydraulic be better than disc?

Shouldn't the emphasis be on finding a rim material that dissipates heat fast? It should also be: light, strong, long wearing, shiney and expensive. (Aluminum is pretty good but it flunks long wearing and expensive.)

I think I've got it! Titanium! Doesn't that meet all 5 criteria? Deep, aero titanium rims. Who could ask for more? Perfect for todays Vuelta descents. Can't get them too hot. ("Course with the rain and high altitudes, heat is something the riders want!)

CK, Magura makes some hydraulic rim brakes, we had a Cervelo P4 in the shop with them, not that great, and heavy, but had a pretty sweet set up for a Tri bike. It belonged to the Magura Rep.

I have ridden both the Shimano and SRAM hydraulic brakes, they work, and modulate very well, it's only a matter of time really, I remember all of the hub bub over Mtn Discs, and now that's the only way to go.
I understand the service course vehicle issue, without everyone on them, safety issue's, but when Gilbert said he was worried about being burned by a hot disc, I really don't see that happening

Hydraulic rim caliper will provide all the advantages of disc brakes (more power, better modulation) with none of the negatives. No aero drag penalty, no weight penalty, no new frame, QR or hub standards, use your existing wheels.

The bikes I have seen with the Magura brakes have been exceptional....light lever feel, plenty of power and great modulation. haven't yet tried the SRAM calipers yet, though

Ben's point re: braking amterial is an excellent observation, however.....carbon os far from an ideal braking surface. In that sense, he is right....however, that doesn't change the fact that the purchasing public wants carbon wheels and rims. Woe to the companies that try and convince them otherwise....they don't want to hear it.

The carbon wheel issue is huge IMHO, not having to design a wheel around the forces created with rim braking has led to better rim design. Carbon MTB wheels are becoming more commonplace every day because of this, and these wheels are very strong, almost too stiff in some instances. And some advantages like less rotating mass on the outer rim. Leading to wider rims, which are better all around. No rim wear on your 2500.00 wheel set, etc....
I think the weight thing is a non factor, Pro Mechanics are already having to add weight to bikes to make the UCI weight limit, and companies like Magura using Carbo-tecture technology, you would be amazed at how light these brakes can be, The MT8's on my MTB weigh nothing, they feel like air in your hands
I'm sure pro racing will take years to change, but the bikes are already available to the public

Did the Magura Hyd Caliper thing in 1992 on a Specilized FRS Mtn bike and when dry they probably stopped a bit better but in the slop and wet the same problems were there as with the calipers. I belive the Vee brakes solved a lot of the caliper dry stopping but the wet was the same. Disk solved the wet stopping problems and it was cheaper to replace a disk than a rim after a trip through the slop. And if I remember the Magura calipers were a bitch to adjust properly.

Yup, the old Magura's were interesting, heavy as hell, not that great, almost had to dis-assemble just to get your wheel off, but, they were hydraulic! And they were Hazard Orange!!
Amazing how far we have come since then on the MTB, and the roadies will find out what they have been missing soon enough, all I say is, if you get a chance to ride SRAM or Shimano hydraulics anywhere other than a bike shop parking lot, do it, you will be shocked, and amazed.
My brother past away this past spring, I had to take care of his bikes, his old S-Works MTB had those old Magura's, I re-did the bike with V-Brakes, and donated those to the local MTB Shop museum......

Just had a week of mountain riding, ton of technical descents, wet and cold as well as hot and dry. Lots of 20km long descents. Shimano Ultegra brakes w Alu rims; you really don't need anything more than that. The performance difference with the friggin Tiagra brakes I had on Ventoux rental is staggering.

I'm running Sram 11v hydraulic disc on my Focus Mares CX bike and really like the set up. Much more confidence inspiring diving into a technical section.

For all the "it's not necessary... overkill... blah blah blah..." um OK, I suppose that's why cantilever and rim brakes are so popular on mountain bikes.

Whoa, there....I'm not saying they don't have a place on CX bikes or gravel grinders and even some road bikes. Schitt,I'm was the guy that regularly enjoyed tweaking a certain troll who insisted that discs would never come to CX or road bikes!!

However, as they sit now, I don't think they are a suitable application for road racing and that most of their benefits can be achieved w/ hydraulic calipers.

Lets see, a carbon bike with carbon wheels. electronic shifting, disc brakes. What will that put you back, 9K for starters?

Some people have too much money to spend. Seriously, not even being a retro grouch. Maybe road racing needs to be a "spec" series like in auto racing. Everyone uses the same equipment, and it's about the rider.
