Just in time for the upcoming WorldTour season, SRAM will be offering up a new way of slowing down. Surely thanks to the number of road bikes moving to direct mount instead of center mount (like those of Team Katusha Alpecin), SRAM has cooked up a DM brake of their own. Born from their S-Series, the new brake will play well with any SRAM mechanical road group whether it’s Apex or RED eTap.

Built with a similar design language to their previous rim brake calipers, the S-900 DM will clear 28mm tires and is designed to work with modern wide rims.

SRAM also calls out the fact that the synchronizer screw which helps center the brake is offset which they claim reduces the splay force (energy that flexes the fork or seatstay rather than squeezes the rim). Note that while this brake is front and rear compatible, it is not compatible with chainstay mounts – only seatstays in the rear.

Claimed weight is 326g for a caliper with a set of the included SwissStop Flash Pro brake pads. Sold individually, brake calipers will go for $125 and will be available in March 2018.

60 grams heavier than SRAM Red regular calipers.

It’s 326g a PAIR, the article here is incorrect. SRAM gives the correct info in their press release.

Do brakes clear 26.99 mm tyres?

326g for one caliper? Surely that can’t be right…

Sram cannot make hydro brakes. Their cable pull are actually decent, but holy fudge they need to give up entirely on trying to make hydro brakes. Literally every generation of sram hydro brakes that come out we are told “they are just as good as XT’s” and every time we laugh at the sram rep and say “it’s funny that your benchmark for hydro brakes is something that shimano created about 7yrs ago now”. Like clock work, the moment their hydro brakes are released to the public we are on the phone with sram warranty getting junk replacements for their junk “new generation”. You should see their fix for their latest Level and guide brakes. They just send you a box of new levers. As a mechanic this is one area of sram that has just blown me away is how they cannot get this right. They have had so many years to “be just as good as XT’s”

To srams credit their warranty dept. is easy to work with and at least the rest of their group is pretty decent.

Meh…they’re all about the same. SRAM, Shimano, Hope, Magura,TRP, whatever. They ALL have problems. I’ve seen just as many warranty issues with XT’s as anything else. I would still choose SRAM hydros over any other brand, mainly because they do offer solid warranty support. The same can’t be said for every other company.

I find performance to be about the same, when it comes down to it. The DOT fluid is nasty stuff though, and enough to make me keep using Shimano.

Tons of people agree the XT brakes have an inconsistent and/or overly long lever throw with no real fix from shimano. The newest generation of sram hydro brakes have actually been quite reliable though and have great performance

Wow, if that weight is right, those are really heavy. That would be a reasonable and believable weight for the set, as it is twice the weight of some Dura Ace DM calipers, not to mention eeBrakes and Bontrager DM brakes.

I may be misunderstanding, but it seems like there’s nothing stopping designing a DM caliper that has significantly better tire clearance. It’d be super sweet if someone made some DM calipers for 32mm or 35mm tires–would be great for average road riders seeking a more compliant ride, and not otherwise needing hydraulic discs.

I think those are called cantilevers…

Fair nuff (or centerpulls for that matter) but I feel there’s a market segment that wants cleaner lines (and ostensibly better aerodynamics) than cantis and does not need their mud clearance. I’m thinking more of a DM replacement for mid reach caliper brakes 47-57mm. Even as a marketing differentiator being able to officially state 32mm compatibility would be a sell for some users.

Looks to me like the mounting bolt spacing is is the driving width factor for DM brakes. You can’t make that any wider without changing the standard, which means changing frames.

Good point. I’d have to check out some bikes but it seems like on the bikes I’ve seen the closest tolerance is the top of the brake.

It was kind of a joke but it does seem like cycling “innovation” has been going in circles
