Rotor pumps out new Uno hydraulic shifting road group w/ Magura brakes

This is nice! I just hope it wont be anywhere near as expensive as Acros’ hydraulic shift systems. Should be lighter than both electronic and mechanic groups too.

This system will live or die simply based on how easy it is to bleed. If they don’t blow every other hydraulic bleed process out of the water in terms of how easy it is to perform by the home mechanic it’s not going to survive.

“assumed in Europe.”

I assume you mean assembled? <3

@Elk
I dare say that if you can run a Di2 line you’ll be able to run this hydraulic line. Only thing I can think of that would make it difficult are cable stops.
@Ryan
I’ll take it from your dealings with ‘simple’ electronic groups you’ve never done a firmware update and setup on a Di2 TT bike? And if Magura had a hand in designing this then I’d bet that bleeding it would be dead easy.

I still don’t want it but I think many of the points I see people bringing up are non-issues really. Yes there are going to be issues but there are always teething problems with new technology. If companies didn’t try to push new ideas we’d all still be riding wooden rimmed, single speed bikes with drum brakes. *Cue hipster who is still riding wooden rimmed fixie.*

this makes SRAM look really smart for pursuing wireless.

All that f1.4 bokeh is making the components a little tough to see.

When can I order it?

I love the fact that BikeRumor has this before BRaIN.
@Craig, true points. Magura does good work. Di2 on TT bikes has caused me many grey hairs

So did you really ‘find’ those patents and read them well enough to understand all the details in the last rotor/hydro post? If so, and there was no tip-off and no explanation of it all from someone at rotor, I’m impressed ; )

@Larry Falk
I don’t know about touring. If your bike tour is so long that you will need to change the cables from normal wear, chances are you would also need to bleed this system at least once. And the latter seems like a much more difficult task to be performed on the road.

“…chances are you would also need to bleed this system at least once.”

How absurd. Larry said specifically 7 months. A hydraulic system can’t last 7 months without a bleed, Francois?

kudos for trying something different but (bleeding as mentioned) and reliability have to all but eliminate this from non-pavement riding – doesn’t it?

thankfully, internal routing should help with the protection but (n=1) I’ve had two instances in the last two seasons of rocks nicking my front brake line. thankfully one was a slllllooooowwww leak but suddenly not being able to shift or brake? that would be awesome.

never understood why people are so scared of bleeding hydro lines, its a super simple process that doesnt take a ton of time.

I’m also one that doesn’t see any real downside. Bleeding is basically a one time process. These won’t get hot (like brakes) and any small amount of water absorption into the fluid shouldn’t cause an issue if the internals aren’t ferrous. Fluid should last a looooong time (how often to people bleed their car brakes – I’m pretty an@l and only do it every 2 years except on a car I track which is more frequent. I think most only touch it when their mechanic says “you need new brake pads”).

As for cable stops – just go around the stop if your bike is so equipped and zip tie to the side of the stop or to the tube. Cable stops aren’t needed in a hydraulic system.

If you like mechanical shift groups (as I do, try to keep all electronics off the bike functioning parts) then this is a HUGE step forward from cable systems. No stretch, no friction, no wear. Instantaneous response. Cable routing and bends not critical to performance. Again, huge improvement to mechanical systems.

Maguras brake system to bleed in MTB are hell compared to Shimano. Magura brakes in MTB are desigend by SWAMPBOB himself. Specialized dumped Magura for 2016 MTB lineup. That Rotors hydralic system is provided by Magura dont say anything.

For the hydralic allover I dont think it is a bad idiea, maybe this is the future…no batteris to load and put on the bike, ni wires to change after two seasons. And in 2017 when hydralic discbrakes are allover this can be a nice allover solution.

One other advantage over a mech system is that it can’t be contaminated by water/dirt pulling into the cables. That could be a big advantage for CX/gravel riders.

Hydraulics also have the potential of being VERY light. With (I’m assuming) much less pressure than a brake, many of the components could be made of alloy or carbon reinforced plastics rather than the steel needed for cables. You also don’t need return springs for the derailleurs. Although it does look like they went for one for the rear maybe for a single line rather than an up and a down.

Very cool, can’t wait to see more info next week.

Yet another solution for a problem that doesn’t exist.

Bikeradar mentioned that the reservoirs were on the drailleurs. If that is the case, then I would expect that they are either still cable actuated, or are wireless. Anyone know?

Very interesting, can’t wait to read and see more of this.
Brave move to challenge the big guys with an innovative product. I hope it can live up to it.
How will the distribution and service be organized?
What will the price be?
What will the guarantee terms be?
How user installation and service friendly will it be?
How available will it be (Internet only, LBS:s, etc.)?

JG – yep there would need to be a dedicated MC for each function, so one for the brake and one for the shifting. They can share reservoirs though (kind of like a brake MC and clutch use the same reservoir)

@ JG
Look at how much potential volume you have on the inside of the brifter hood, and see how “small” the cylinders are for e.g. XT / XTR disc brakes. I bet you could easily fit everything inside the handle in a neat way as long as you start planning and drawing things from scratch.

I’m not so sure a proper master cylinder is even necessary in a shifting system. There’s very little line pressure compared to a brake system and there’s zero necessity for heat dissipation.

The more I read about Di2’s, Hydro’s, Wireless’s ….the happier I get to have cable actuator systems working GREAT on all my bike. Like not even $200 on ebay and fully equip my bike.

Why would I want hydraulic shifting when clearly wireless is the future? I understand the brakes, but the rest? Each to their own, but personally my next bike will have hydraulic disk brakes and electronic/wireless shifting.
