Not sure if this has been discussed before or not
Be interested to see if SRAM or Shimano develop hydraulic shifting also

Hydraulic Shifting for MTB

A chap in the states tried it years ago. Scott Allen fife enterprises if I remember correctly. SAFE shifter I think they were called. Worked really well by all accounts and retro fit to existing mech and shifter. Just suffered from being too far ahead of their time.

The Acros system looks lovely but not at $1999!!!

Whats the advantage over cables? Must be heavier to have a master cylinder. slave cylinder and a tube full of fluid compared to a cable
Posted 1 year ago # -
Yep very expensive but maybe once more developed or mass produced costs could drop
I think it sounds more promising/reliable than electric shifting
I mean what's happens if you're out on the trail and your battery conks out

I suppose you have a point but.....,
What was your opinion when they brought out hydro brakes
Posted 1 year ago # -
Lighter shifting, less maintenance, no more gritty cables, or linked cables. Get the price down to a few hundred quid and I'm very interested. I think a retro fit system for existing shifts and mech would increase acceptance though. As cogs and chains get more tightly packed, I can see this improving shifting accuracy an awful lot.

Easy for companies like Hope to develop as well

I've been thinking about something similar for a while for my Rohloff.
With two full length cables and a twist grip, in muddy conditions I have got to the situation where I need two hands to change gear.
I was thinking of a small hydraulic pump and reservoir on the 'bars and a small hydraulic motor on the hub.Posted 1 year ago # -
Hope are already prototyping a remote reservoir for road sti. They just need the slave cylinder and they're laughing. I hope they're reading this.

German website lists it as 175g lighter than XTR kit. Not entirely sure how they fiddle those figures though.Posted 1 year ago # -
The link does not work for me can others see it?

They fiddle the figures by not having a relatively heavy return spring on the mechs, and some rather nice cnc work on everything.

I like. Except for the two cables per mech (what it looks like).
With a remote dropper, and a remote fork lock out, and two brakes, you're going to have 8 cables running around the bike. Just with 2x10 and a rear brake you will need 5 cables going down top tube or down tube. Think it would look kinda messy.

Internal routing..... job done!!
Or if they were really clever they could combine all the hoses so you could brake and shift at the same time or the other way round

Like the sound of that.

dont see the advantage been running same cables on my bike for 2 years and never had a problem or needed to adjust more like a solution to a problem that never was
Posted 1 year ago # -
How easy is it going to be to adjust them in the arse end of nowhere when you smack the mech and bend it on a rock though? At least with cable you can usually have a play and get a few gears working alright.
Posted 1 year ago # -
Actually, as there's no return spring, if you smack it, you just position the mechs by hand and they will stay there until you move them somewhere else. Much easier than trying to finish an epic with only one gear!

Hmm, going to have to read more about this then!
Posted 1 year ago # -
I love the idea, really want this and I think it's the way forward. I just don't have that sort of cash. Couple of hundred quid over XTR components and maybe but at £2k, it's not happening for me just yet.
Posted 1 year ago # -
all they have done is buy the german company that already made them, slapped their name on and given it more press, years old this stuff
5roc or something

Good idea but I think electric offers more possibilities and weight savings. Would shat my pants if I came off and had this on my bike... would just make riding my bike too stressful, counter productive

I'm waiting for Bluetooth mechs controlled by a brain-ultrasound device.

Less shit to go wrong. Yes please.
Posted 1 year ago # -
very bling but very costly would need to come down massively in price as I see very little advantage over a cable tbh unlike brakes which are much better as hydraulic

How do you know that hydraulic gears don't? Do you have any experience of both systems?
Posted 1 year ago # -
Cable shifting works perfectly well. What advantage hydraulic gives I cannot see. More complex, finer tolerances needed extra weight
Posted 1 year ago # -
hydraulics are great for transferring lots of force - hydraulic brakes make sense.
i haven't really thought about hydraulic gears, i guess maybe they'd cope with grit and water and mud a little better than cables, but at what cost? - discuss...
(and i don't just mean price)
Posted 1 year ago # -
yep - press the hydro shifter too hard and it'll push the derailleur right off the bike...
