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)

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.

They did not change the levers for this version. 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.

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.

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.

yes there is, it is a closed system like the Magura's and Racing line rim brakes. You could use a Racing Line Lever with the brakes though :)

We are using the lever with Racing Lines cylinders for the back brake

David Hoffmann also wrote about having used the BFO levers with his Magura slaves. 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

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?

don't see an issue with you writing a good rider tested them and decided to go back to HS33. 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 :)
