Rever MTN1 dual-pull mechanical disc brake caliper for mountain bikes

In April, Rever launched their MCX mechanical disc brakes for the cyclocross crowd, offering a budget option that still provided the performance boost of both pads moving inward simultaneously. We’ve posted our first impressions of those and a long term review is coming soon.

Now, they have a mountain bike version coming that’s optimized for the cable pull found on flat bar levers, and they’re bringing it to market with an impressively light machined lever as part of the package. Stop in for details and weights…

The MTN1 calipers get different ramps to adjust cable pull for mountain bike levers. They used larger steel balls on the cam plate creates more power by pressing harder against the pad, and they provide more immediate response because they also move the pads inward faster.

Pads are top loading for quick changes.

The MTN1 will retail for $165 per wheel and comes with everything you need to set it up. That includes the lever, which is just 67g each. spins on a plastic bushing. The caliper acts as the return spring to keep it simple and light. Apparently, a lot of people were loving on the levers, so they may start selling those separately down the road.

What about selling the caliper separately ?

So it’s a TRP Spyre?

No, the MCX1 is a Spyre-like design, and for the “budget” crowd at $125 per wheel…

This is good news. The BB7 is already a great brake, but it’s good to see more options for good mechanical disc brakes. I wrote to Rever earlier this year and asked if their CX-road brakes are compatible with Shimano Ice-Tech rotors, and they said yes, they are. But- they don’t work with Ice-Tech or other finned pads; it would be fantastic if they did.

Tim, in a mech disc brake is cooling the issue that it is with hydro?

@Freddie- I honestly am not 100% sure. But logically, fluid expands when it gets hot, which CAN lead to problems. You can either use DOT stuff which does not expand much but is toxic, or use mineral oil, which is not toxic but does expand. One reason Shimano made IceTech pads and rotors is precisely because their brakes use mineral oil, so it is critical that they stay cool.
Mechanical brakes have no such problems, at least with fluid. Cables are unaffected by heat. But pads and rotors or not; a mechanical system with finned pads and rotors would be really COOL. Of course, mechanical brakes have their own inherent issues. Unlike hydros, they do not adjust automatically for pad wear, and they have (for me very minor) issues with cable stretch and contamination.

Basically and exact copy of an aluminum spyre. But cost more than a carbon spyre. Not sure why these exist.

So with Shimano SLX available for less than $100 per wheel, why does anyone want or need these? I don’t understand what they offer that the hydraulics don’t. Must be missing something, please enlighten me.

Scott- I think we’re missing something, but I’m just not sure what it is.

@Bob, I’m with ya. Hydraulic brakes have never been so totally super-duper amazeballs.

@Bob- they will work in extremely low temps (mineral oil brakes in particular tend to feel ‘gummy’ or stop working in cold temps from what I have heard. These brakes are expensive; TRP’s do the same job for less from the looks of it. Me- I have for years chosen to ride mechanicals over hydros. I’ve ridden hydros on friends’ bikes and been impressed, but wouldn’t switch to them from what I have. I’ve never understood what was so absolutely magical about hydraulic brakes.

$165 per wheel? You can get Shimano XT Hydraulic for $120-130! $165 for wheel set would be more like it.

@scott while they look to be a copy of trp, they appear to cost more b/c they include the lever. Possible they are selling it as a package b/c they want the rider to get the most out of the brake by using the lever they designed to be used with the brake. I do agree it is expensive considering the current options out on the market.

@Ryan- I don’t see much special about this lever. If you want ultimate power from a cable-operated system, choose something with Servo-Wave or an equivalent of it (older LX, XT, and XTR levers, plus some SRAM ones from the early 2000s).

@Tim,
I’ve been running some BB7’s with XT servo wave levers, compressionless housing and good cables for a while here and have notices no appriciable difference between them and simple Avid single digit levers.

I’m looking forward to upgrading to either these Rever’s[can’t help but think that this has to be a refrence to Serentiy….] or the TRP’s.

@martini- Newer Shimano XT levers don’t include servo wave, older ones do- but it does not function out of the box, it needs to be activated. If your lever does have servo wave, you need to actually activate it. Pull the lever, and where the cable attaches you’ll see two little flat half moon shaped plastic bits. If you look at the lever from the underside, you’ll see these plastic thingies are held in place by tiny screws. Unscrew them and take out the plastic bits. Now the cable carrier can slide/ roll closer to the lever’s pivot, changing the leverage ratio as you pull. If you can’t see what I am talking about, your lever doesn’t have servo wave.
This servo wave, used on some XT and XTR levers, is incidentally the worst functioning type of servo wave. After some use, the slot the cable carrier rides in develops a notch at the top, which makes for unpredictable braking. The cable carrier gets caught in the notch, it can’t roll down. Then it is able as you pull harder to break out of the notch, but drops all the way to the bottom of the slot, turning your brake into an on-off switch.
LX levers have servo wave function without moving parts. Older SRAM levers are also good and have a similar function, but are made of plastic.

Yes Tim, if I didn’t know this, I’d have posted something different. Thanks though.

martini- Hm. I’m just surprised I guess that you don’t feel a difference. For me, the difference is night and day. I’ve used a few servo wave levers with BB7’s and found the power to be actually too much, uncontrollable in fact. Are you the same martini from the mtbr.com VRC board?
