The fact that they're made by germans is what worries me. I've seen forks and even a few frames permanently deformed outward from hs33's. Way too powerful.Engineered by Germans - I am pretty sure the will be just fine. Much easier to route the break cable and hide the break on triathlon frames.
I'm sure that Magura tuned the brakes to give the proper amount of braking force, and didn't just turn it up to 11 to splinter wheels.so they've been announced....
hydraulic RIM brakes for road bikes... why? i foresee crushed carbon road rims in the future.
These brakes attach separately, they don't brace on the frame like the HS33s did, which attached to canti studs.The fact that they're made by germans is what worries me. I've seen forks and even a few frames permanently deformed outward from hs33's. Way too powerful.
Just wait grasshopper...PR is going to be interesting I bet.I'd kill for hydro discs on my road bike with carbon wheels. Might be the best "innovation" for road bikes in the past 10 years.
my point was more that hydro rims are strong enough to deform forks and frames, they're going to be strong enough to shear off a single bolt that road bikes mount to.These brakes attach separately, they don't brace on the frame like the HS33s did, which attached to canti studs.
But that's not how road brakes work, when you squeeze the brake, no matter how hard, you're not putting that kind of stress on the bolt. Sure, there are forces from the slowing of the wheel that impact it, just like a cable brake, and at a certain point it'll lock the wheel, just like a cable-actuated brake, so there isn't any "more" braking power. It's just on a TT/Tri bike with super-funky routing, most brakes are kind of "suggestions." To bring the same power to those bikes as you would enjoy on a road bike is the point of these.my point was more that hydro rims are strong enough to deform forks and frames, they're going to be strong enough to shear off a single bolt that road bikes mount to.
yes, its a cool innovative product, but 2 problems:
1) its gonna be obsolete in the near future now that disc brakes are poised to enter the road market
2) magura's recent track record for new innovative products is far from stellar. even chainlove can't move their forks.
Discs weren't legal for UCI use three years ago, which is a giant part of it.The rim brake hydros make some sense if you absolutely must have terrible cable routing on a TT bike. Maybe also for the very small handed people who have trouble getting sufficient brake force.
Regarding discs...Avid didn't have the marketing power to make them popular enough all those years ago?
all this proves at the the UCI is a bunch of dinosaursDiscs weren't legal for UCI use three years ago, which is a giant part of it.
Avid's first try into discs on CX bikes sucked when they used the mtb BB7's. the road BB7's arent that much betterRegarding discs...Avid didn't have the marketing power to make them popular enough all those years ago?
Yep. My QRoo could've done with a parachute to slow down on the final descent at Gila...60mph+tt cable routing=fun.But that's not how road brakes work, when you squeeze the brake, no matter how hard, you're not putting that kind of stress on the bolt.

It's going to take a while before discs are everywhere. And hey, maybe this is a stepping point for them, a stopgap, and we're all on discs in 2 years.
But there are plenty of people with tri bikes now that I think would benefit from this brake as an upgrade to their current machine.
Forks and brakes are very different things though. Magura are brake people, I'd trust them, give them the chance.
I remember a bunch of reviews and threads that said the road BB7s were good, but frame and hub selection was limited and really there wasn't much of an advantage except in cruddy conditions. Also the UCI thing. But most people aren't racing UCI races.Avid's first try into discs on CX bikes sucked when they used the mtb BB7's. the road BB7's arent that much better
unless shimano actually releases their brake this year, then i dont see that happening.I am willing to bet you will see tons of disc brakes on road bikes by the end of the year
On the back tire for sure, on the front, straight-line... not sure.I remember a bunch of reviews and threads that said the road BB7s were good, but frame and hub selection was limited and really there wasn't much of an advantage except in cruddy conditions.

For me it usually seems like the coefficient of friction between tires and the road is the limiting factor in braking.
that can be said for pretty much any road brake in the wetWith the rim brakes, in wet conditions, I could not stop in a hurry, with these, they are much more responsive...
I think you might be overthinking the tubular thing alittle too much. A tubular race set up for mountain bikes have a gluing surface that isn't much larger than a road tubular, and they're subjected to stresses way more obscure, violent, and frequent than a road set up. As long as the glue is done right, I doubt it'll be a factor.As far as tubulars go, I think it will add some weird stresses to tires if the brakes really try to stop hard. I just don't know where they fit in really.
its called modulation. if a brake doesnt have it, youll lock it up without knowing/wanting toAm I the only person on the planet that thinks that the stopping power will just brake traction when applied?
Brakes can be tuned, so no more stopping power, but more usable, especially in conditions like rain, etc, or with carbon wheels.Am I the only person on the planet that thinks that the stopping power will just brake traction when applied? The contact patch on a road tire is so small, I don't think I can imagine it will hold. In wet weather, I see this really being the case. I may end up being wrong, but I'm likely to not ever put them on a bike.
As far as tubulars go, I think it will add some weird stresses to tires if the brakes really try to stop hard. I just don't know where they fit in really.
Plus significantly safer for carbon clinchers. And braking on carbon can just only get so good, especially in the wet. Discs would really solve that issue.Plus rims can be made lighter, as they won't have to have a braking surface, and more aero for the same reasons.
I ain't no physics expert, but ordinary road brakes do not rotate and I don't see how they impact rotational mass.Also disc brakes put the weight at the hub, having less effect on rotational mass.
That's what I meant. I know rim brakes don't rotate around the wheel (der!), but rims have braking tracks for the pads. By moving the brakes to the hub, then the rims can be lighter, reducing rotational weight.I ain't no physics expert, but ordinary road brakes do not rotate and I don't see how they impact rotational mass.
We will probably see some rotating weight reduction at the rim once the manufacturers start making disc-specific road rims with no brake track. But even when that occurs, it seems clear that discs will add weight overall. The brake components will be heavier and the frame and fork need to be beefed up to accept disc mounting and handle the braking loads.
That said, count me in for disc brakes on a road bike, eventually. It's a no brainer, particularly with carbon rims.
