RISC Brake Evo 3

I wish I had a mill so I could make cool shit just cause.

Keep up the good work.

I rode the first couple of versions of this brake for over 2 years then went back to maguras and echos for about 1 yeah then V's for about half a year. Nothing beats this brake! Maintenance is nothing, ridiculously powerful in any weather oil/shit what ever you have on the disc it still works. Yes I do smash the hell out of it quite a bit if im rough but it can hangle a lot of abuse. No big deal to give it a tweak with your hand every few weeks if youre unlucky. The rim stays a lot straighter with the disc mounted. Adds 305grams over my echo setup.

Your evo3 just made me think you had earlier versions so I look down and you did... rad! nice progression with it man. you new mounting looks heaps stiffer and should help performance heaps.

As for releasing, could you use something similar to the magura RimBrake quick-release you get on 'V' brakes? And your lower mount on the top of the stay I would make alot longer to spread the load.

Regardless of that keep it up! I love seeing innovation and new engineering.

Hah, I love that thing. And it feels fucking amazing. At least the old one did, I'm sure this is even better.

Daaannnnggg. Very cool. Where are you getting those rotors?

Interesting. At first I was wondering why you had the caliper on the inside, but now I see it. Very cool for what it is. If I had to give any sort of input, make the mounting points for the rotor more button shaped and a little closer to the rim so they're less obtrusive. They might already be, but I can't really tell from the pictures

fuck. yes.

Needs a Hope Mono Trial caliper, that would be intense... never slip.

I have an intense desire to ride one!!! Good work!

You could put a Tektro caliper and be fine. It's a freaking 20 inch rotor.

This.^

Trials needs more genuine innovation such as this. If some manufacturer made this i would gladly buy it, no matter the cost. And im sure many others would to. Great job man!

We need to get this to market there's not enough innovation in trials hell we are still using ISIS cranks for christ sake.

Yeah the mounting points arnt very nice. I was thinking of doing the same as the Ruthless and welding tabs to the rim. But theyr magnesium so im shit at welding that. Surprisingly though they dont get caught as much as you would think. I tend to always be on a slight angle when I slip the back off something. What has happend though I was running really low pressure and the tyre folded over and punctured.

Funny you should say you could ride a Tektro and itd be right. Coz thats what it is. Tektro Auriga Pro. Dirtiest cheapest brakes out there, $195 for two! If they dont leak I think they could actually be nice brakes, so we shall see.:eek3:

Freaking sick! :eek5:

Forget teh 160 - 185 - 203mm disc argument.. 600mm+ :naughty:

LOVE this set-up!

if you tweak your rim a small amount would that tweak the rotor quite a bit? also i tend to know wheels out of round slightly; how does that translate to brake performance?

ohhh yeah I'd love to feel the braking power of this!!

The amount you tweak your rim tends to translate less onto the disc as it has quite a bit of spring and wants to stay straight. Even when its had a good smack and its rubbing like crazing its not as bad as when a magura drags.

The disc has 10mm of braking surface but the pad has 15. So you have that 5 mill of play for when the wheel is out of true.

The bitchy thing is having horizontal drop outs. When your chain stretches obviously you will be moving the whole disc closer to the calliper. Iv made it so the calliper mount can be adjusted to accommodate. Not ideal though. Also removing the wheel is a bitch but I fix punctures with the wheel on anyway.

Does the disk float on the pins ?
