The lastest edition of SRAM Eagle Transmission is here and is dubbed S1000. The group is not mechanical (as many of you had hoped) and consists of a new crankset, rear derailleur, and cassette. There is no price info because the group is slated for OE only, not aftermarket...for now?

Press Release Below

Eagle Transmission is the realization of the dream to fundamentally change the way we shift and ride a mountain bike. It radically simplifies, strengthens, and extends lifespan to new limits. It uses no derailleur hanger or adjustment screws and lets you shift flawlessly under maximum power. And now with the introduction of new T-Type components to the Eagle Transmission Ecosystem, it delivers the dream to even more riders.

SRAM S1000 EAGLE CRANKSET

FC-S1000-C1

The S-1000 Transmission crankset features a sleek, sturdy crankarm engineered for robustness and reliability. Like other cranks in the Transmission ecosystem, the S-1000 crank features 8-bolt ring compatibility and a stamped steel or aluminum ring with optional bash guards for durability and protection on the trail. Cross-compatibility with chainring options and bashguards allows for easy aftermarket customization.

Features

– Forged aluminum crankarm with 8-bolt ring compatibility
– Integrated composite bashguards shared with GX and X0 Eagle Transmission
– 155mm, 160mm, 165mm, 170mm, 175mm lengths
– Stamped steel or aluminum chainrings
– Compatible with all SRAM T-Type components
– OE availability only

SRAM S1000 EAGLE E-MTB CRANKSET

FC-S1000-PA-C1

The S-1000 Transmission E-MTB crank is a sleek, sturdy crankarm engineered for robustness and reliability. This unique design is forged from aluminum for robustness and dependability without compromising weight. SRAM, Brose, and Bosch motors pair with our “gap cap” for an aesthetically pleasing integrated look.

– 150mm, 155mm, 160mm, 165mm, 170mm lengths
– SRAM, Brose, Bosch, ISIS variants
– OE availability only

SRAM S1000 EAGLE TRANSMISSION DERAILLEUR

RD-S1000-A1

The S-1000 Eagle Transmission derailleur is the entry point to the Eagle Transmission ecosystem. Utilizing the same striking architecture as our GX Eagle Transmission derailleur, the Full Mount design mounts around the wheel axle itself with no hanger required, bringing strength and durability to UDH-equipped bikes. Cassette Mapping, a marriage of the derailleur’s firmware with the hardware of our T-Type cassettes, helps deliver the best shift under load, even under the added power of an E-MTB. And like all Eagle Transmission derailleurs, it’s rebuildable, with replaceable skid plates and two-piece outer link, and a removable cage assembly that simply rotates off. Featuring a sleek black-on-black appearance, this derailleur can be mixed and matched with all other T-Type ecosystem components. The S-1000 Eagle Transmission derailleur also features our new Drag Spring Cage Damper for reliable chain retention and long-term durability.

– Compatible with all SRAM T-Type components
– Shares GX Eagle Transmission architecture with sleek black colorway
– New drag spring cage damper
– Hangerless Interface, Full Mount attachment method
– Radically clear setup process, no adjustment required
– OE availability only

SRAM XS1270 EAGLE TRANSMISSION CASSETTE

CS-XS-1270-A1

Housing the same medal-winning technology as our other Transmission cassettes, our XS-1270 Eagle Transmission Cassette offers incredible performance for more riders. Finished in a unique nickel chrome, this cassette is quiet, durable and features a replaceable gear cluster. And for the first time on a traditional splined driver body, features a full 10-52t range thanks to the integration of the 10-tooth cog and lockring.

– Complete 10-52t range
– Gears 8-12 (10-12-14-16-18t) are a replaceable cluster
– Splined 8, 9, 10 Speed Driverbody compatible – steel Driverbody material required
– Full X-SYNC design for best-ever inboard and outboard shifting performance under load
– Unique black nickel chrome finish
– 55mm chainline compatibility for more moderate chain angle, longer wear and greater precision. Setup Cog for simple set up
– Compatible with all SRAM T-Type components

Any weights being announced?

Am I the only idiot waiting for 11s wireless? The cassettes are so much lighter and cheaper!

What is a "drag spring damper"? Google is not providing any clear explanations.

Sounds to me like it is the spring system used in the derailleur clutch

Well, yes, but how does it actually function compared to a roller-bearing clutch or a ratchet clutch?

It’s called marketing

This feels like the product no one was asking for. Maybe SRAM knows something about the MTB market that I don't, but doesn't it seem like a mechanical Transmission has 1000% more market interest than an SX-level battery-operated system?

Visually speaking, not one of those components looks like it’s under 900 grams alone.

I think they know what sells to OEMs (not a bunch of crusty forum nerds).
 

pretty sure OG wireless Eagle sold like 10x what they anticipated originally.

This reads as an attempt to FORCE manufacturers to spec something they have no interest in trying to upsell to the consumer.
SRAM minion - "OEM isn't wanting to spec this at the price point we're offering sir."
SRAM corporate overlord (former at Coca Cola) - "Buy ad space on all the websites.  Consumers will scream for it & they' have no choice but to accept our margins."  followed by a Mr. Burns level chortle.

I just can't wait to explain to a customer that replacing the derailleur on their brand new $3500 alloy FS bike (as this will end up on those bikes next year) will cost $600 (Current cad pricing for GX transmission RD). Or I can replace the entire drivetrain with Shimano Linkglide that does the same thing, for a few dollars less.

And how often are you suspecting you’ll get the complaint of “my shifter stopped working”, only to find the battery is dead?
 

the SX/NX crowd doesn’t strike me as the type to do their own maintenance or remember to do things like change a battery on a bicycle (based on the folks I see on the trails, half of them aren’t lubing their chain, so derailleur battery seems like a big ask).

I use 11s Shimano and I would totally go for that!

This! Until they get this to the market at much lower prices, I don't see the point really. A derailleur is so exposed and it is discardable, whether we like it or not. I'll stick with my trusty 11s XT system.

This feels like it's aimed at lower end OEM e-bike market, so OEM can buy an entire SRAM/RS package at a lower price. The 12sp HG body cassette is the most interesting part.

A lot of people around me are really tempted by GX Eagle AXS. They would take it over a mechanical X01 system even.

I just don't get the appeal of the electric systems.  I've not tried any of them, but my XT shifts great.  I can't actually fathom better shifting than I've already got from a mechanical system.  You don't know what you don't know though, so perhaps they're great.  I'm very particular about the mechanical operation of my bikes though, so everything is very well maintained.

I see this as a move to get more frame manufacturers to be able to drop rear-derailleur-cable routing from frames.  Each frame design has a lot of price points and if you can't spec cable-free rear shifting across all the price points then you have to design cable routing in. 

In the next 15 years, I'm 99% certain that I'll never own a electric shift bike and I'm 99% certain that I will someday have an e-bike.  Perhaps I'll be forced into e-shifting then, but by that time they will have already surpassed the "automatic transmissions are the greatest and everyone must have it!" dumbing-down of MTB threshold.

Well there you go, you said it yourself you haven't tried it. It's better. I've run just about every drivetrain you can put on an MTB, and XT is pretty far from the pinnacle of what's out there. I'd go as far as to say it isn't even in the top five.

7/4/2024 11:35am

OE only for HG hubs? Like why u cannot source xd? 

Which means it will be impossible to replace the cassette when it wears out. All other T-type cassettes are for XD drivers.

I can’t imagine that shift cable ports are the reason frames are expensive. Ya got 4 of them on most frames. It’s not like frame prices can drop $1000 by not having shift cable ports. I’d suspect these add no more than $50 to a fancy frame. Maybe $100 if there’s internal tunnels. Anyone who knows better correct me. 
bikes are incorporating reach, head angle, chainstay, and suspension adjustability. it seems silly to exclude shift cable ports, especially when there are gonna be brake and seatpost ports anyway.

Already a thing on the new Stumpjumper. I'm willing to bet the big S won't be the only ones to do this, especially on the higher end models.

I don't really follow road bike trends, but I believe it's already reasonably commonplace in the curly bar world.
