Calipers

The Tech 4 is compatible with X2, E4, V4 and Trial Zone calipers.

The 4 piston calipers have been updated and utilise stainless steel pistons with a phenolic insert for “smoother movement and less maintenance, while still being able to manage high temperatures without heat transfer during extreme use.”

We’ve got a set of Tech 4 brakes on the way to us as we speak, as part of a future 4-pot disc brake group test.

Press Release

The all-new Tech 4 is more than just a change of colour and logos. It draws on 25+ years of experience designing and manufacturing hydraulic brake systems, to create a brake that not only has increased power but also delivers that power consistently from the moment the lever is pulled.

Designed with the rider in mind, the Tech 4 has an increased hydraulic and mechanical ratio. The result of this produces a linear relationship between brake pressure and lever force making it easy and intuitive to control the power. The increased mechanical ratio has also been fine-tuned using real riding data and extensive dyno testing making it the most efficient at lever forces typically used during riding.

The internal sealing is all new for reduced friction, and the pivot spins on roller bearings, allowing the spring rate to be reduced. This lower spring rate gives a lighter lever action, reducing rider fatigue, whilst keeping our legendary feel and modulation.

Combined, all the changes result in the best balance of feel and power. Power that is useable throughout the full range of reach and bite point adjustment, whilst still producing a 30% pressure increase over the Tech 3 for a given force.

The Tech 4 uses a hinged clamp to reduce weight, and the reservoir area has been increased to lower the overall stack height. Shifter integration has been improved and now offers 30° of angle adjustment as well as neater packaging and compatibility with the latest shifters. Lateral adjustment on both sides of the master cylinder is also possible to give a wide range of lever position options whilst retaining the tool free bite point and reach adjustments from the Tech 3.

    Currently on Tech 3/ E4 combo and love them. I understand the gains must be due to the lever length, but these look like four finger touring brakes. Would be interested if the levers were shorter…

    They might be compatible with other Tech 3 blades, though knowing Hope these days probably not. But maybe.

    It actually looks the ideal for me on the ebike, and maybe thats also where they’re going with these. Coupled with the E4 or V4 calipers.

    Joe Barnes did a bike check recently and he showed how Hope had made him a custom level which closer resembled the tech3. I’d like to know if the new pistons in the calliper are compatible with current E4s.

    Not just Hope, but where does everyone making brakes keep finding this extra power from? Surely distance X force at the lever = distance X force at the caliper. I don’t imagine the losses in the system are significant. The only way to get more power (reduce lever pull effort) is to increase lever throw and/or reduce required pad throw (by reducing pad clearance or funky servowave type gadgets).

    ignore – you said increase lever throw -not lever length

    I think Hoe have made the 15% extra power claim over the last 7 changes to their braking systems 😆

    Lever length, revised cam position and narrower piston in the master cylinder according to the pink site

    Is it just me that can’t unsee the channel 4 logo on the reservoir cap?

    Looks like the master cylinder/cap will finally be able to be easily positioned level to the ground, making bleeds easier.

    Is there any indication of when the levers will be available separately?

    Available in 31.8 and 35mm due to have far inboard you need to mount them.

    Is the blade from the pivot to the tip actually any longer than say a Trickstuff Maxima? It maybe looks longer due to the BPC and reach adjust being placed after the pivot, but is it actually longer? I know it’s longer than a Tech 3, but…in comparison to other modern brakes without a servo?

    “It’s a new brake lever!” – meh.

    “It comes in sparkly colours” – wait, no, I’m in!

    “And here’s the price” – fffffffffffuuuuu…

    That’s not how pressure works.

    You’re having a barbecue and you invite your semi-pro rugby player mate round with his petite supermodel girlfriend. He’s wearing trainers, she’s in stilettos, which one is going to make the biggest mess of your lawn?

    Never mind new levers. Where are the old stock Tech 3 being sold off cheap?

    Premier Icon kimbers

    So 30% more power

    apparently 20% from redesigned levers and 10% comrs from organic race pads- so a cheap way to upgrade tech3

    Would the tech 3 levers work with a SRAM code caliper? I really like my code brakes but the feel at the lever has too much lever throw…I’ve adjust the rsc lever but still not got it adjusted enough as I like a short lever throw.

    Would the tech 3 work? I had these previously and loved the levers as they were properly adjustable.

    The hydraulics are just a mechanism for transfering the mechanical advantage.

    What do you think the pressure difference is between the hydraulic fluid just behind the master cylinder piston and that just behind the caliper piston?

    when testing have a look at calliper flex? as i have a set of v4 and you can see the calliper flex and bulge when you apply the brakes and squeeze. you will find that is where a lot of brake power is lost.

    Evocycles have some tech3 discounts, its weird how the press haven’t had some samples to verify the power claim before public release, I wanna see the underside of the lever for shifter adapter set up.

    Will be interesting to see how they play against the Tech 3s, with a stated 20% increase in power due to the increase in pressure, that’ll change the modulation a bit, if the pads are adding 10% i’d expect to see some data of that with the Tech 3s as well?

    Think it’ll be a few more years until i try Hope again, not out of anything bad, i just like 1 finger levers and brakes, so have pretty much been Shimano or Magura the last 5 years.

    That’s not how pressure works.

    It is when you link it together with geometry.
    Volume displaced is area of piston x travel.
    Pressure is force / area of piston.

    So, with the same calliper, you can increase braking force by increasing pressure, so reduce area of the master cylinder piston. But you need to displace the same volume to engage the pads on the disc surface so you need to move the piston at the master cylinder further.

    I love it when folks display their ignorance. I’ve done it myself.

    I’d like to know if the new pistons in the calliper are compatible with current E4s.

    I asked them this, they said they are backwards compatible. So new e4/v4/x2 pistons fit their respective previous generations.
