Rever's Attack and Arc Hydraulic Brakes - Taipei Cycle Show 2019
Rever's Attack two-piston brake costs $95 USD per end.
Rever, an off-shoot of Jagwire, might not be the first name that comes to mind when thinking about brakes, but their mineral oil-based Attack and Arc models appear to be straightforward, gimmick-free options that could make sense.
The Attack is their lower-priced model that sells for $95 USD (without a rotor) and sees a sturdy looking top-end combined with a two-piston caliper, all of which comes in at 235-grams. Rever was refreshingly straight with me - the Attack isn't meant to blow minds with its technology, but simply be a reliable, powerful brake that'll sell for a reasonable price. Up top, you're looking at a left or right-specific design with a split clamp, a two or three-finger lever blade, and a reach adjustment dial that skips the tiny hex key.
That funny looking orange thing is a vented aluminum extension meant to help dissipate heat, much like the fins on Shimano's IceTech pads.
Down at the wheel, the Attack gets a forged caliper that's home to a set of 22mm diameter pistons. You can also spec their 'Heat Dissipation Cover' Shimano-compatible pads that combine a vented, 0.6mm thick aluminum top panel with 1mm thick steel backplates.
The Arc brake is positioned a bit more up-market than the Attack, with an MSRP of $105 USD (without a rotor) and a host of upgrades over its less expensive brother. The most obvious is up top, with the Arc sporting a much slimmer, pared down perch. Internally, it uses a dual bladder design that said to save weight while also making it easy to run the brakes moto-style or the proper way, and you can choose from a two or three finger lever blade.
The caliper is different, too, although it's difficult to spot. You'll find a set of 24mm pistons in there if you look hard enough, with Rever saying that the larger diameter supplies more power than what's used inside the Attack's caliper. Total weight is about 15-grams less than the Attack, too.

The Arc brake weighs less than the Attack and offers more power thanks to larger diameter pistons.

I reckon it would do much more to grow mountain bike as a sport and a business than any UCI/RedBull TV tricks.
For the money I'd just get the real things, and by that I mean Formulas because SRAM.
I have the Slate t4 G-Spec on my hardtail. The brakes are ok, but I don't like the power.
Btw the TRP Slate doesn't have any fancy stuff like servo going on in their lever, that's actually one of they selling point saying that simplicity and direct drive of the piston allows for their excellent modulation. If you even have these brakes just look at the lever, the shaft goes directly from the lever blade to the piston.
Thanks
Well I will try the Saint metalic pads and also I will mobilize the pistons.
Mobilizing pistons alone can make such a huge difference in power.
I will keep the simple TRP brakes. I just hope they will working longer without any issues than Shimano's.
The only flawless experience I made so far with high-end MTB brakes are Sram brakes who just keep working no matter what and have super nice feeling.
But damn, TRP brakes looking so freaking rad. ( Moto design....love it )
They just have to work. I really want to keep them and be as good as possible.
Mineral oil fo life!
