OH please let that last link be true.

Hydraulic shifting???
Be still my beating heart. :shock:

:mrgreen:

I was told on friday that the 11 speed red, titled "22", will be offered with a Hydraulic option

They seem to struggle to fit a master cylinder for brakes into the shifter. I am intrigued as to how they'll fit two master cylinders?

So super naive question. . .I've never used hydraulic brakes. Is there that much of a performance upgrade over cables with hydraulics, other than the initial cable stretch? Same with potential hydraulic shifting? I can't imagine the system would be any lighter, either.


I haven't gotten to try hyrdaulic rim brakes yet but word is from the Magura TT system that the power and modulation is improved but there is also cleaner routing of cables and the power and modulation are unaffected by tight bends in routing required for aero bikes with hidden brakes.

Its another way to open up integration and improve aerodynamics.

Acros has hydraulic shifting. It can be lighter, mostly because the lines are lighter than steel cables in steel reinforced housing.

But I don't think Sram 11 will have hydraulic shifting. That's going too far for the market at this point.

@geedawg

Hydraulic shifting/braking:
-Super durable, virtually no maintenance. Probably less maintenance than electronic, actually! You'll only need to bleed the system once per year, which is a quick procedure.
-No cable stretch. Set it once and forget it... all year long.
-System is lighter - hydraulic lines (with fluid) are lighter than housing + cable, less moving parts in derailleurs also makes them a bit lighter (at least it did on Acros' hydraulic system)
-No fade. A cable actuated brake will have a fade in power, a hydraulic won't.
-Smaller points of entry for hydraulic lines into components makes their envelope smaller (and hence, in a sense more aero) (except for the lever, which isn't as crazy big as the pictures make it look but still could use a bit of revision in future runs)

@eric
We can hope though. Where's that hopeful, daydreaming smiley face when I need it?

Of course for every upside their is a downside. You don't get as much fade with hydraulic brakes but you can get vapor lock if the system heats up. But overall i think hydraulic has some possible upside. Word on the street is the new 11sp red will have a hydraulic brake option but not shifting.

As far as the 2 largish master cylindars, nothing says they have to be at a terminal end they can go anywhere with the proper development

> A cable actuated brake will have a fade in power, a hydraulic won't.

Fade comes from the brake pad overheating. A hydraulic disc can have better leverage than cable, allowing it to use a higher temp but harder pad compound that fades at a higher temperature. A hydraulic brake can also fade if the fluid overheats and starts boiling. That is often the cause of fade on cars and motorcycles.

I would not say that using hydraulics makes a brake impervious to fade.

Here's a good article on bike disc brake fade and road bike disc brake design: http://www.bikerumor.com/2012/02/14/roa ... they-work/" onclick="window.open(this.href);return false;

That is the exact opposite of what I'm wishing for. I sincerely hope if they go with hydraulic shifting they don't lock everyone in to their brakes as well, as great as I'm sure they'd be.

No one's mentioned the leaked photo still has a cable clamp bolt on the '2014 hydro rear derailleur'...which tells us someone's playing with photoshop.

"leaked photo" aka photoshop job is on first page, privateer posted it from the newsbike.com link earlier...which was originally posted on April 1 :wink:

What I know
11 speed is coming this year - '22' is the marketing, they believe shimano/campag groups can't be ridden in all 22 gears while their group can...hence true 22 speed
is it mechanical/hydro/electronic? you'll know soon enough.

A few days ago I was reading my old cycling magazines and one issue (should be an early 90's edition) covered a new mech sytem that contained the index system in the rear mech in stead of the shifter. So cable stretch couldn't influence the performance. Why didn't anyone developed this further? To me it seems a good solution for quick shifting with high precision.

Cable systems are a thing of the past. In 20 years, the only cable systems are going to be the cheaper groupsets. There is no reason to invest money/time in a system that is very slowly going out.

As for fade with rim brakes, not going to happen. The slave cylinder is so far from the source of the heat, you're going to have much more to worry about that that.
