Trialtech Sport Hose Splitter


Sold out

This item is usually NOT suitable for routing two disc brake calipers to one lever, but can be used under very specific circumstances - please contact us for more information.

- High quality, 6061 aluminium, CNC machined hose splitter for hydraulic rim brakes.
- Tested over a significant period of time with Trialtech team riders such as Stan Shaw.
- Helps to prevent damage to vulnerable cross-overs found on standard brakes.
- Increases brake efficiency and feel by ensuring even fluid flow to each cylinder.
- Large internal bore doesn't restrict fluid flow, especially when compared to rival models.
- Uses three M6 barbed fittings (not supplied) for easy hose connection and replacement. Not compatible with M8 shroud nuts / olives such as those found on many disc brakes. If you're unsure which fittings you require for your cylinders, feel free to ask.
- Not quite as light as integrated barbed fitting options, though cheaper, stronger and easier to fit.
- Bleeding is simple: just bleed one side of the system as normal, cap it off, then bleed the other side of the system.
- Can also be used with disc brakes for custom applications, but please note it is not a straightforward conversion. There are quite a few factors to consider such as thread size of you hose fittings and leverage ratios of the master and slave pistons. We have experience of these potentials issues and are happy to discuss them with you, don't hesitate to give us a call if you are unsure.
- Available in Black or Silver anodised finish with stylish Trialtech 'Bashring' laser etched logos.
- Supplied fully packaged with Trialtech stickers enclosed.
- Weight: 5g



Am I right in thinking that the thread in this splitter is M6? Thanks.

Yes. Thanks, Adam

Apart from 3 barbed hose fittings, are there any other parts needed to fit the hose splitter into a standard magura hose set up. Eg, do you need a bolt to plug the redundant hole in one of the slave cylinders?

Hello - You'd need to use some form of blanking bolt in your cylinders, but aside from that you'd be fine. The complete fittings you'd need depend on which cylinders you have. Blanking bolts aren't usually made in an M8 size, so you'd need to close off the M6 bolt hole. If you've got an M8/M6 cylinder then the best way is to use a shroud nut and olive on the hose going to the splitter, then an M6 bolt to close the cylinder. If it's an M6/M6 cylinder then you'll need to use a barbed fitting on the hose going to the splitter and an M6 bolt to close the cylinder. Quite often you'll be able to largely use the fittings you've already got with your brake - I'm using this same splitter and managed to recycle the fittings I had on my complete brake to attach the hoses (apart from the 3 barbed fittings going to the splitter). Thanks, Mark


I've got some Magura HS33 rim brakes from 2008 and always had problems with centering once the pads start to wear - the cylinder directly connected to the lever would retract fully and the other hardly at all. If I get a set of these, is this likely to sort this out? As a general question, how long would you guess the HS33 set will last before I have issues with the cylinder/lever seals etc. which aren't repairable ? Just wondering if I would be better moving to something new rather than spending the money on patching up the old set. Many thanks!

Hi David - thanks for your question. From your description it sounds as if you might just need to bleed the brakes. If you wind the TPA all the way out and can then pull the lever a little without moving the pads, you need a bleed. One pad might move before the other - if that happens, you should also try bleeding the brakes. If the pads move as soon as the lever moves, then it's likely that the slave cylinders have just gotten encrusted with gunk as they're five years old. You can set one of the pads right up against the rim and take the other clyinder off the bike and remove the pad. Pull the lever and the piston will move out, and then you can drop some lubrication on there. That should help break up any dirt or gunge that's stopping it from moving properly, then do the same with the other. Whichever issue you find you have, this product would likely help neither. Hope you get it sorted - if you're still having trouble, don't hesitate to email/call us for more help! Thanks, Flipp.


Hi guys, Using one of these splitters, what effect would it have on the brakes, if any, if i were to leave the crossover in place?

Posted by James on 12/07/2013

Reply from TartyBikes on 15/07/2013

Hi James - thanks for your question. I'm afraid you wouldn't be able to do that. The main purpose of a splitter is to eradicate the need for a crossover. If you used the extra two holes to mount one to the slave pistons, you wouldn't be able to bleed the brake. It would also be entirely redundant. Thanks, Flipp.


Could I use this splitter with 2 braided steel cross over hoses?

Posted by Scott on 20/12/2014

Reply from TartyBikes on 22/12/2014

Hi Scott - thanks for your question. Yes, you could do that with no problems, assuming you have all the correct connectors etc. Thanks, Flipp.


Right now I have Magura MT5 discs installed. My goal is to keep my main rear brake lever on the right, and have an additional mini lever on the left side; each operating/going to the same rear caliper using a "Y" splitter. If I were to use an additional MT5 lever (which incorporates the master cylinder), would this work, or would it put too much pressure on the opposing piston in the lever not in use? The lever appears to be strong enough not to break and withstand being pushed in the opposite direction it is designed for... I don't know if I am forgetting something that would create an issue if I kept them at the same level.

Hi Kevin - thanks for your question. We are unsure about whether this would be OK on those levers or not as it's not something we've ever tried, but the splitter itself couldn't work with the brake hose and fittings. The splitter uses M6 fittings, which cannot work with disc brake hose. You would usually be able to change to Hope hose and fittings, but because of the special thread on the shroud nut at the lever you couldn't do that. Sorry about that. Thanks, Flipp.


hello i ve magura HS33 and good ridge braided hose , i like to buy Trialtech spot hose splitter ,,,can you help me out hose connector between trial tech <m6> to good ridge hose x3 please thanks

Posted by tim on 23/04/2016

Reply from TartyBikes on 25/04/2016

Hi Tim - Our Hope Hose Spares should fit your Goodridge hose fine. If you head over to the Hope Hose Spares product (Quick find code: 010808), in the 'Additional Information' box there's a list of fittings you need for different applications. The Trialtech splitter has M6 ports on it, so by buying 3 lots of the items listed for "M6 hole on brake cylinder" you'll have all the parts you need to attach your hose to your splitter. Thanks, Mark


will this fit a hope nipples?these are 5.8mm actual size but maybe it will be a m6 bole like this one

Posted by h on 16/06/2016

Reply from TartyBikes on 16/06/2016

Hello - As long as you're using the M6 or 6mm Hope fittings then they should fit in there fine. Thanks, Mark


Hey, I'm a 4th year mechanical engineering student doing an FYP for the shell eco maraton, I need to split a hydraulic brake to have 2 brake calipers being run off one brake lever. It is a three wheel single person prototype car weighing about 100kg with the driver, does this product suit this purpose?

Posted by Ryan on 23/10/2017

Reply from TartyBikes on 23/10/2017

Hi Ryan - We've had several Eco Marathon teams over the years get in touch for this very same reason! Depending on the brakes you use, this splitter can do the trick, although the size of fitting required means there's a very select few brakes that actually work with it. Our custom Magura MT2 Twin Caliper Disc Brake (Product code: 13126) shows it in use, and may be a good option for you. You're welcome to specify the required hose length for us to get it just right. Thanks, Mark


Would this fitting work with a Shimano Slx M7000? http://www.chainreactioncycles.com/ie/en/shimano-slx-m7000-disc-brake/rp-prod148226

Posted by Ryan on 25/10/2017

Reply from TartyBikes on 25/10/2017

Hi Ryan - This won't work with any Shimano brakes as their fittings are all M8, whereas the ports on the splitter are M6. You could potentially machine an adaptor, but it might be tricky. Thanks, Mark

Kenneth Martinsson

Do you think this will work with a Cannondale Lefty lockout and a Rockshox Monarch XX lockout instead of the Rockshox XLoc Full Sprint.

Posted by Kenneth Martinsson on 30/03/2018

Reply from TartyBikes on 02/04/2018

Hi Kenneth - Unfortunately we don't have any experience with those products so couldn't say for sure, sorry. If you can e-mail us with some more info about the parts you're hoping to use we can check their compatibility out with the Trialtech Splitter. The main limiting factor will probably be the fitting size though - the Trialtech Splitter requires M6 threaded fittings, and if your existing hoses don't use them then chances are it won't work, sorry. Thanks, Mark

ian grace

Would this allow me to have two brake levers for one caliper - i have Di2 hydraulic brakes on my cross bike but also want to fit a crosstop / flat bar lever for when riding on the tops. Will this allow that?

Hi Ian - Unfortunately Shimano hose fittings are incompatible with this splitter, sorry. Most of Shimano's fittings are M8, but this splitter uses M6 fittings. Thanks, Mark

Great product!

Posted by Seth on 10/04/2014

A great idea having the splitter threaded instead of 3 integrated barb fittings. Setup was easy and it keeps the pistons actuating symmetrically instead of one before the other. No leaks after 6 months (water bleed)!!! Thanks again Tarty for classy performance parts! -Seth
