SRAM announce hangerless Eagle Transmission drivetrains

Bit off topic, but I struggle to find the GX AXS specific topic.

Since I have now moved parts from my MTB to my Gravel bike, I noticed my AXS has a lot more inertia than my former APEX (I had to replace the freehub body to move from Apex to AXS) or than the XTR that I put back on my MTB (same freehub body).

When ever I pedal at comfortable/quick cadence, if I suddenlty stop pedalling I get a bit of a kick back in my right crankarm from the chain. Nothing to cry about, but feels a bit ***, kind of like if you don't put the clutch on on your XTR. The chain doesn't look loose, and B tension screw seems alright.

If that new hangerless tech has the same feel, even if it shifts perfect under load I'm not gonna like it (to be honest most of my current setups (XTR/GXAXS/Ultegra Di2 11spd) already shift fine under load provided you don't shift 3 gears at once at very slow cadence)

That sounds more like a freehub seal or bearing dragging than an issue with the drivetrain, unless it's the extra inertia from the 52T cassette over what I assume was a 36T before?

YT is full of clowns jumping on their bike frames to prove the derailleur doesn't break. How do you reckon force of a riding crash impact on the indestructible derailleur will affect frames - surely more force is going to be transmitted to the chain and seat stays? 

 

A few years I attended a course. Axs installation was demonstrated and the trainer made a lot of the overload clutch.

he challenged all present to give it a bash. I asked are you absolutely sure …? Yes…?

so I moered it. Several times. I basically saw Jacob Zuma and kicked the crap out of it. The derailleur just kept coming back for more , much like Zuma but it never got corrupted. I ended up bending the hanger but the derailleur just laughed at me.

I figured if anyone was going to damage that derailleur it was going to be with a stick of 🧨 dynamite. 
mad for durability I’m sold . That thing takes more knocks than a mechanical unit.

the frames are very strong in that area. All the wheel and drivetrain plus suspension loads are going through that area. 
 

is there an angle that the force can act through that can result in failure? Yes I’m sure there is

this new t type can’t rotate backward as far the mechanical units can and therefore should not wrap around the cassette and shear the frame. The parallelogram links will fail first (hence the out link is replaceable)

If I had the money for a new bike with this kit I’d take it in a flash. Far less to service. With the connectamajig on the brake hose a headset bearing is easy to replace without a complete brake bleed.

it just flipped expensive but by next year it will discounted by many online retailers because that is where the market will be in  terms of disposable cash

on the MTB I kept the same cassette when I moved from XTR to GX then back to XTR.

When the XTR derailleur has the clutch on I don't have that kickback, I do have it when the clutch is off.

On the gravel bike the wheels are fairly new (about 2000km), but yes, I did go from a smaller 11spd cassette to the massive 12spd mtb cassette

I was having this problem on my old 9 speed 105 groupset. I could not work it out until I checked the jockey wheels. They were the old non bearing variety and were poked causing the chain to bind on the cage at the lower pulley if i back pedalled even a bit while free wheeling. I swopped the pulleys for some used 10 speed XT bearing pulleys and the problem went away.

Yes it does have that advantage for the rest of us but in fact all you have to do is shop around for Shimano Deore, brand new. My wife just went next level on her 10 speed 1x with an 11 -46 cassette and 10/11 speed derailleur for the massive sum of R1400.00. 

But your wife is tougher than you, so she can

She is tough  but in fact I am tougher and I run 11-42 10s on my HT and 10-42 11s on my heavy bike. 🙂

I reckon this is going to be what gets me to finally convert to AXS.

Patiently waiting for the GX version...

When you have to replace your whole bike to get the latest shift tech to fit ...

Nope, my bike is UDH compatible.

That is the same view people had when 29'ers came out ... and when longer travel AM (Sorry, #Enduro bikes came out) .... this will all roll out over time, we have to also realise this is just being released, and it the real cutting edge of SRAM's drive train, so by the time that they have taken this to more base level drivetrain ranges, frame manufacturers would have started adapting.

Under each one of those there's multiple models 

 

udh is very common on any bike that's been made after 2020 

 

this " just need to buy a new frame......"  line is already getting old 

i think you would be surprised how many people ride bikes older than 2020....

but then again , if you riding an older bike you probably not the target market....

I'm just trying to state that bikes with the UDH are not uncommon, and it only came out in 2019 so if sram designed something to fundamentally work with a standard that came out in 2019 people can't really fault them for that

Did you buy your bike new or used?

If you bought new, you may have been the target market for something ... wider rims, boost, etc.

If you bought second hand you managed to skip the premium for a new bike, and bought a bike from someone who did buy a new bike. At some point you too will end up buying a great condition used bike with a UHD.

Took a little break from Bikehub, and it seems my logical thought processes have been missing around here

If I had an older bike that's not UDH compatible but wanted to upgrade to AXS 12 speed eagle, this new transmission is out of the question.

Assumption here is that current AXS 12 speed will be discontinued and once sold out they out. 

I do like this advancement in tech and the 12 speed AXS is something i would be interested to upgrade to.

I am aware that there is will still be stock of older AXS and there is still a 2nd hand market but I am highlighting a valid scenario where this new tech is not available to you unless you upgrade your frame.
