SRAM Eagle Transmission Review: First Ride on “E.T.'

The SRAM Eagle Transmission is an all-new drivetrain that’s unlike anything we’ve seen before. In our latest video, Neil helps us get acquainted with this futuristic, Extra Terrestrial group. He talks through everything you need to know, including the direct mount derailleur and how it works, their updated cassette spacing, the new X0 aluminum crank, pricing, weights, and so much more…

I thought I was used to everything being expensive, but those prices for the cassettes and chains made me wince. For disposable parts it's crazy -- I hope this isn't a precedent for other groupsets.

i'm glad you mentioned the price, and felt it was a bit hefty. alot of "bike" sites dont really talk about it. these new technologies will trickle down from the top of the range stuff and be more "affordable". BUT bike companies aren't reinventing the wheel they are just tweeking designs that have been around for years. i understand that having an app to adjust the setup will cost money to create. I've always felt that all bike related parts are more expensive than they need to be. i'm glad that companies like ltwoo and sensah exist. i'll be looking to utilize their components when i put my gravel build together

I am running a 3x9 speed SRAM X7 derailleur from 2011 and triple oval Rotor front chain rings, both bought second hand. On a steel bike from 2008. Still working flawless. Bought these parts because I used the original Shimano parts for another steel second hand frame bike build which I later sold. My last build, mostly all second hand parts, is on a third hand steel On One Inbred frame which is also from 2008 I think. Two bikes, one soul. Parts can be swept, maintenance is dead cheap and bombproof. Gear range is awesome. Cost was less than a XO drivetrain. I wonder how long it takes for these new standards to become obsolete and when they do if still will be able to get replacement parts then. I wouldn’t put my money on this new stuff as far as that’s concerned.

Would love an update if you start getting a feel for how much shorter the battery life is on this new transmission compared to the older SRAM wireless systems.

Whew! That was a lot of info. Thank you for being so thorough. It will be interesting to see how all of this affects standards and tech moving forward.

Shimano, TRP and Microshift all sent flowers to SRAM with a great big thank you written on the card.

Is my calendar off. Is it actually April 1st?

[kennyness]

AdventX for me. All the range I need, works great, lasts well so far, and a new chain and cassette is $75. For everyone who is not an elite racer, SRAM has lost their minds.

[chmullins]

$1600 groupset mounted on a $800 bike mounted to the roof of a $400 car heading to the trails...this is the future of mountain biking folks.😅

[grumpy-dad]

Would love a wireless derailleur but not when it cost more than my current bike brand new.

[kennyness]

Makes me want to just get a Rohloff: Same price/weight, more reliable, and easier to use.

[echtogammut]

Let me get this strait, when you crash the derailleur will now bork your frame? Also, frame manufactures rely on the loose tolerances allowed by derailleur hangers and through-axle surfaces are rarely perfect, since this derailleur lacks the adjustment allowed by the hanger it will need some other kind of adjustment mechanism, which isn't immediately apparent. I'm usually a SRAM fan, but this looks like a very poorly thought out design.

I have SRAM NX on my FS (UDH equipped) bike, Eagle AXS XX1 on my HT (non-UDH) bike. They’re both great!
I’ve had Eagle AXS for four years and I can’t wait to try ET. Up to now, the only thing 12spd. Shimano XTR does better is shifting under power. If ET durability is as good as Eagle AXS AND it shifts well under full power, then it seems worth the money. The flattop chain and cassette will probably last a time, btw. My Eagle AXS chain and cassette are still going!
I get that this isn’t for everyone. Racers will fund the development of lower cost versions, if history repeats. Until then, enjoy what you have, even if it’s a $400 NX group set.

If I wanted to run Transmission on my 142mm (non-boost) gravel frame, what kind of chainline and crankset do I need? My current Eason EC90SL has a 47mm chainline, which I assume will not be optimal.

[danieleflorean]

interesting that Sram comes out with this on the high end while shimano seems to be focusing on the low-end with their new universal 9 to 11 speed drivetrains.

[larrywhite]

OK why is this good thing? Regardless of price the whole goal of the der hanger is to be sacrificial - ie they break and this is a good thing. So now we have a very rigid der tied right into the dropout, and when we crash and we all crash how is this going to go?

[backcountryFLcyclist]

I chew through at least 2 cassettes a year. No way the $600 cost of this cassette is 10x long lasting than a $60 cassette.

[ryanthompson]

I can't even bother to swap out my hg freehub to run a gx cassette on my bike because the nx are massively cheaper, So this is insane 😂

[slimjimever]

Why not loose the derailleur all together? Belt drive hub gear that actually perform & lightweight will be ideal

[leobardonunez]

May be I missed this info but does this set work with a mountain bike from 2009?
