SRAM Launches Eagle Mechanical Mountain Bike Transmissions with Full Mount Interface

[News bot]

Press Release: First, we delivered the dream of the perfect mountain bike shift. Now we’re delivering the dream of ultimate performance for the mechanical mountain bike transmission too. This is Eagle Mechanical Transmission. The world’s first mechanical groupsets to use a Full Mount interface instead of a derailleur hanger. The first to let you shift anywhere, under absolute power, without compromising or compensating. It’s the world’s first mechanical system with incredibly easy “prepare, hang, tighten” installation, no adjustment screws needed. Rebuildable. Reliable. Affordable. Mechanical Transmission is the dream, delivered. Eagle 90 Transmission Eagle 90 Transmission delivers the dream of the […]

Great stuff from SRAM

[CARANXCycleMobile]

and now they offer reliable shifting !!!! finally 😅

But for those of us with older frames this isn't an option. Viva Shimano!

I am still weary that now there are a plethora of bits within the derailleur that can be bent when you inevitably knock your derailleur making fault finding a nightmare. Sure replacable bits are nice, but figuring out which one is slightly out seems difficult.

Usually if there is anything iffy to your shifting, step one is check a bent hanger. And 80% of the time thats the issue. (As Seth from Berm Peak says, to check your shifting issues, throw your hanger in some water and if it sinks, its bent)

The electronic ones has some mediation to this by the motor giving way a bit under a knock, dampening the impact. This is not an option with mechanical. 

Is this one of those "problems" that did not need "fixing"?

Mechanical has always had a built in break away clutch. It’s called the return spring. The electronic systems needed a dedicated break away clutch because the stepper motor was permanently engaged. The break away clutch changed that. For any mechanical derailleur the first line of defense is the spring. If the derailleur takes a hit it simply moves to tension the spring (not the cable). It’s one of the things I loved about Shimano’s low normal derailleurs aka rapid rise, the spring was always working to pull the deraileur away from the accident. But because Americans didn’t like talking about their favourite Pfizer drug on Mtb rides, rapid rise fell out of favour……weirdos!

I’ll admit they have my attention now.
 

Although some of the initial reviews suggest the shifting ergonomics isn't perfect. Maybe you just need all those screws to get perfect shifting😅

MMmh not keen to read the whole marketing BS about it, why is it for you guys a good thing ? Unless it's half the price of the electronic stuff ?

Combining UDH and Mechanical seems like something that targets nobody ?

I already think that the XPLR transmission group is completely useless, but this sounds even more useless to me. And that's coming from a guy with an XTR mechanical group on the MTB and a GX AXS Mullet setup on the gravel bike so no hate on either of the main brands nor towards mechanical groupsets.

Id be keeping an eye on this. GX AXS shifting hasnt been perfect for me, and had quite a few mates where battery connection dies midway in a ride. Happened to my partner on Tankwa. Sure, cables can also fail...guess price will be the big decider

i run mechanical stuff because it's just more reliable. I couldn't care less about charging anything on my bicycle. I want to ride it on a whim and put it away dirty.

I guess UDH / direct mount ads to that reliability. So its now actually worth looking at for me. Although i also have no issues with my shimano mechanical stuff. I mean...once you set the limit screws and B tension you never really touch it again...plus, i literally don't care if i break a deraileur off during riding....they are so cheap (shimano). Thats the only drawback of all this UDH stuf....cost.I dont want to treat a dangling bit at the back of my bike like my suspension stantions. It WILL hit rocks.

hands up who has a UDH bike? Just curious?

That's kind of why I'm asking the question, who has a bike with UDH and would like to have a mechanical group. It's kind of like asking who wants a aero road bike with clearance for 32mm tubeless but with rim brakes

It’s significantly cheaper. Eagle 90 derailleur is 45% the price of a GX AXS derailleur. So it brings the stiffness and reliability benefits of Transmission AXS to much more attainable price point. This kit will be specced on sport level and entry level bikes. The upgrade to electronic transmission is cheaper now. 
if you have an older bike you up the creek any way as it’s unlikely to be UDH compatible.

45% of the price of the GX (that let's be honest, isn't very expensive this days IMO for the piece of tech), now we're talking (assuming it works just as good)

Both my previous and my current bike have UDH. I've been eyeing GX Transmission, but I can't get over the cost, so this might just be for me...
