ben_travis Posted August 31, 2015 Report Share Posted August 31, 2015 Cross post from Pinkbike.com - http://www.pinkbike.com/news/hardore-german-techno-eurobike-2015.html Brake Force One Brake Force One have built the first ever brake which uses water instead of hydraulic fluid. Sounds crazy but their engineers say that brake fluids don't get as hot as people think - Magura and Shimano seals aren't designed to take more than 100°C and the only reason we use DOT or mineral oil is because of old technology taken from the automotive where fluid temperatures can get much higher. Brake Force One say that water is actually more heat resistant than hydraulic fluid with two times higher heat capacity, five times better heat transportation and less heat elongation. In direct comparison tests the water filled brakes outlast normal fluids, and the outstanding benefit of water is that it's clean and can be found anywhere. Propylene glycol antifreeze is used to prevent freezing in winter temperatures, and there is also a neat quick release button for the hoses if you need to cut, or re-route them. The H2O brakes weigh in at 188g each and will be available in October for €594 pair. (Editor's note - Don't shoot the messenger) Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted August 31, 2015 Report Share Posted August 31, 2015 Why are the lever blades so different? Ignoring the colour... How long until someone cooks these lol? For trials however, I could see them being good. Especially for their weight. Cheers, Ash Quote Link to comment Share on other sites More sharing options...

Levers came out 2 years ago with the Alu housing, before that it was a kind of plastic. Difference between the levers is a 2 finger lever (left one green) and a 1 finger lever (right one red). My daughter is riding with Brake Force One almost 3 years now, not yet with this verson though. Quote Link to comment Share on other sites More sharing options...
Ash-Kennard Posted August 31, 2015 Report Share Posted August 31, 2015 It was the 2 - 1 finger levers that I spotted the difference. Both look nice. Is the lever body metal? Quote Link to comment Share on other sites More sharing options...
niconj Posted August 31, 2015 Report Share Posted August 31, 2015 Just wondering how this would work when braking for a longer period of time in say... downhill. Boiling water can be sth. irritating in a brake. Quote Link to comment Share on other sites More sharing options...

weirdoku Posted August 31, 2015 Report Share Posted August 31, 2015 They look sweet as but the heat problem is pretty much non existent for trials riders. Unless you get given a pair or you have a fat wallet I don't see trials riders adopting these over whats already out there. And for that price you might as well get the most expensive Hopes or whatever floats your boat and probably have money to spare. They also look like they'll snap at the 2 ends of the bar clamp, can't see much material there. Quote Link to comment Share on other sites More sharing options...
LEON Posted August 31, 2015 Report Share Posted August 31, 2015 Look how thin the caliper is around the mounts, that ain't gonna hold out long on the back of a trials bike. Quote Link to comment Share on other sites More sharing options...

Have been on a trials bike for 2 years now and none of them snapped Quote Link to comment Share on other sites More sharing options...
LEON Posted August 31, 2015 Report Share Posted August 31, 2015 But have they been on the back of a street bike with 203 rotors, rock hard tyres and a 14 stone bloke riding it? Because the difference in force between that an a young light rider doing comp riding is another world entirely. 1 Quote Link to comment Share on other sites More sharing options...
Mark W Posted August 31, 2015 Report Share Posted August 31, 2015 Theoretically there's nothing stopping you putting a Shimano caliper on there I guess? That lever looks pretty nice, even though I'm not usually a big fan of excessively drilled stuff. Kudos to the guy who started that company (think he was 17 when he first got the ball rolling with it?) for just doing his own thing though, pretty ballsy move.

You could use a Racing Line Lever with the brakes though We are using the lever with Racing Lines cylinders for the back brake Quote Link to comment Share on other sites More sharing options...

Wonder what he thinks. edit: He just told me that he prefers a HS33 and does't ride the levers anymore.

Nice, so a new company try and get their name out and you just shoot them down with absolutely no evidence to back up your bullshit. You're such a dick on here 1 Quote Link to comment Share on other sites More sharing options...

You're such a dick on here First of all, it's not a new company and second, the levers have been out there for a while already. What's your problem with me writing that a very good rider has tested them and decided to go back to HS33? BFO don't care about Trials so why would they care if anyone writes that their product may not serve the purpose their product wasn't designed for in the first place?

That does not mean though they don't care about trials! The founder is an ex-trials rider and a lot of his ideas come from trials. Like his latest development the brakes with water in stead of oil. and we give him feedback on the product out of trials he is taking into account in his development. As for their product not being designed for Trials, not sure the HS33's were initially designed for Trials either and I think a lot of riders are using MTB type of brakes, especially if you are using discs. I think only Hope made a Trials specific one and to be honest the trials brake is the same as their light Race Evo one. That being said, I am not stating David made a mistake or does not know what he is doing! Looks like he just prefers the HS33 as other people will prefer the Racing Lines 1 Quote Link to comment Share on other sites More sharing options...
