Dispatch time usually 48 hours, we custom build this item for you. Please read through the product description carefully before ordering!

Supplied as standard with a 420mm lever-to-splitter hose and a pair of 1600mm long hoses from splitter to calipers, but custom lengths are available too!

  • One lever, two calipers!
  • Unique brake system.
- Single lever with twin caliper hydraulic disc brake system comprised of a Magura HS33 Lever and a pair of Magura MT2 calipers.
- These brake calipers are the ones shown in the photos and designed to be used on the left hand side of a wheel / hub. They will function perfectly well fitted 'upside down' on the right hand side, but you will need to modify your mounting bracket(s) and this is not something we can assist with. The fitment type is international standard Post Mount, with 74mm spacing between bolt holes, and you can find more information about this with a Google search if required.
- A Trialtech Hose Splitter allows installation of the twin hoses to the calipers.
- The larger 14mm piston diameter in the Magura HS33 lever compared to the standard piston in the Magura MT2 lever means there is no loss of power despite the lever activating two calipers.
- This system means that both front and rear brakes can be applied simultaneously via one lever.
- Ideal for use on diverse applications ranging from mountain bikes to multi-wheeled dog rigs.
- TPA system in the lever gives easy, tool-free bite point adjustment.
- Split bar clamp allows easy installation of the brake lever even with restricted space.
- Supplied with a 420mm lever-to-splitter hose and a pair of 1600mm long hoses from splitter to calipers. We can spec any length hoses to suit your project - simply select the 'Custom Hose Length' option and specify your lengths at Checkout.
- Supplied as a fully bled, ready to bolt on system (including pads) - disc brake rotors and adaptors sold separately.
- Weight: 457g

We have made a disc brake guidance and information sheet which will be very useful if you are not experienced with disc brakes (or even if you are!). We strongly recommend having a look over it before fitting your new brake. This can be downloaded here.

How does this brake work?

Despite this being the 'wrong' lever for the calipers, this system works because the ratio of piston areas is returned to standard. If you fit two calipers to the original (or any regular disc brake) lever, this halves the amount of brake pad travel, doubles the power and doubles the amount of 'flex' at the lever. So, you cannot use a Trialtech Splitter with two 'normal' disc brakes.

Most disc brake levers have a 10mm piston diameter, so the area of this is around 78mm^2, and the Magura HS33 lever is a 14mm piston, giving a piston area of 154mm^2, almost exactly double. This provides the correct amount of fluid flow from lever to caliper, so the amount of brake pad travel, lever feel and power is the same as the original.

The lever doesn't have an expansion reservoir, but from previous customer feedback this doesn't seem to be a problem. The reservoir is only required if the brake gets very hot and the fluid starts to expand, such as a downhill bike. The advantage of using a 'closed' system lever like the Magura HS33 is that you can adjust exactly how much lever throw is required before the brake starts to bite.

The brake is supplied pre-bled by us, but if you do need to bleed the system in future, there are two ways to do this. One is to bleed from one caliper, up the hose, through the lever, down the next hose and out of the second caliper. Alternatively it is possible to bleed the calipers & lines separately, then bleed the lever itself, and attach the three parts together.

Questions

William

I am thinking of using this on my 26" full-sus MTB for off road riding. I am practicing in my head but it seem like 1. because the front hose is maybe 2x shorter, i am assuming the front MT2 will work 1st 2. because the front mt2 work first, in a jam brake situation (unexpected need to full stop) endo becomes a real issue Is this remotely true? Has it been tested?

Hi William!
Due to the way hydraulic systems work, it's pressure that causes the brakes to be actuated, not flow. As the pressure is the same throughout the system both calipers would be actuated at the same time when you pull the lever, rather than one needing to operate first to then allow the other to operate.
We've sold plenty of these brakes in the past for use on bikes, trikes, dog-sleds, eco-racer car projects and more - they've had plenty of testing, in a variety of scenarios, with no problems at all.
Hopefully this helps, but if you have any more questions, please ask.

Good morning, please can you let me know: a) if this would be suitable for Kona Kula Deluxe 2008 ( http://www.konabikeworld.com/08_kuladeluxe_w.htm ) b) what I'd need to order to have one RH lever controlling the Front & Rear brakes c) if you have stock Many thanks, P

Hi Phil!
In order:
a) It should be possible to fit these brakes to your Kona, although as it's not possible to see the disc mounts in the photo on the Kona website it's hard to say which adaptors you would need. If your current disc brakes use an adaptor to fit a Post Mount caliper, you should be able to re-use them.
b) The lever design is 'flip-flop', so they aren't side specific. As a result, you'd just need to order the 'Custom Hose Lengths' option. The standard brake has a fairly long hose to the splitter and then two equal length hoses to the calipers, whereas you would be better off with a shorter hose to the splitter, then two different length hoses to suit your front and rear brake. If you're able to measure out approximate lengths for these, simply add them at the 'Notes' section at checkout and we can make them that length for you. If you're unsure of lengths we'd recommend going slightly longer - it's easier to shorten the hoses should you need to rather than lengthen them!
c) These are currently out of stock, but we should have more available in the near future. If you'd like to receive an e-mail when they become available again, please select the 'Custom Hose Lengths' option, enter your e-mail address in the box below the product variation and click the 'Notify Me' button.
Hopefully this helps - if you have any more questions, please ask!

Hi! this looks like exactly what I've been searching for to upgrade the mechanical twin front disc brakes on a Johnny Loco cargo bike (https://johnnyloco.com/products/1/cargo-cruiser). However, I am a bit concerned about mounting one of the callipers upside down; will the braking area remain the same with a direct replacement of the existing left and right handed callipers i.e. is the cylinder of the MT2 callipers symmetrically placed, in relation to the mounting holes, when viewed from each side? THANKS! David

Hi David - The caliepr piston isn't symmetrically positioned between the bolt holes. The calipers will function like this but you'd have to tweak the mount slightly to make it line up. Thanks!

Hi, I am looking for a replacement for a Magura Big Twin disc brake set up for the front brakes of a tadpole trike. Would the MT2 twin be a suitable replacement? I understand the MT2 is designed for mounting on the left of the hub however one of the calipers would have to be reversed for one of the tadpole's front wheels. Is it ok to operate in this configuration?

Hi William!
As far as we're aware this should work fine. We believe we've had customers who have used it for the same application before.
If you have any more questions, feel free to ask!

Can the brakes be applied to a cargo bike on the two front wheels? I m actually mounting the Bengali Helix 2.5 brakes with 160mm disks. Are the mounting holes compatible? Are the callipers specular?

Posted by Fferri

Reply from TartyBikes

Hi Fferri!
We have sold this brake to riders using them in a similar application in the past. It loks like the Bengal brakes use the same post mount standard as the Magura calipers fitted to this brake so you should theoretically be able to remove your existing brakes and replace them with this brake without needing to change anything.
If you'd like us to double check, you're welcome to e-mail us some photos of your setup and we'll do our best to help out!

Perfect brake upgrade for trike riders.

Posted by Rob

Bought to replace a dual caliper mechanical brake across a tadpole trike front axle, the difference is night and oranges. The mechanical system due to the different cable lengths to each caliper has differing friction causing the closer brake to apply first, and only then does the tension overcome friction enough to apply the furthest brake. No such issue with this hydraulic system since all pressures are equal both calipers move in tandem. Brake steering eliminated. The other major benefit is the Magura system is silky smooth with application of force with a little finger sufficient to stop the trike, allowing for much more precise braking rather than the all-or-nothing encountered with the old system. The quality of the parts and assembly leave no scope to complain, and communication with the team at TartyBikes throughout the transaction was excellent. I literally could not be happier with this purchase.

Hi Robert!
Thanks very much for your detailed review.
It's great to hear you're getting on well with your new brakes, and that they've made such a positive impact on your trike!
