New eagle drivetrain…. What the heck?

I live in the north east US and I have killed a fair number derailleurs and d hangers in my time. Sram’s new derailleurs remove the hangers. They spend a lot of time showing you can drop the bike on the new derailleur and not bend it….. thats nice but all of my derailleur killing events have involved STICKS. I ride more tech trails and the trails are not always clear. Had more than one stick get caught in the spokes and bend the derailleur around the top of the wheel….. the hanger fails and the the frame is ok….. now with these new derailleurs are so beefy, you frame is going to get trashed. Zero interest in frame killing derailleurs…. Funny how all these BS reviews skip the whole stick thing on mountain bikes…..

only time will tell...

but also, I'm mostly not interested because that's way more money than i ever care to spend on a derailleur.

curious to see he cost of parts on these. as well as how easy/not easy they can get knocked out of alignment.

SRAM, more like scam.

The fact that there's no way to adjust the clutch on their derailiuers when it either loosens or fails, renders them only fit for the bin or trash can when it eventually happens.

Not fair on the consumer, but great for company profits.

i could be wrong, but the intention is that the derailleur is fully servicable with replacement parts.

Unfortunately @bamalamadingdong on the latest versions the clutch is most certainly not as it's an unserviceable sealed unit.

On earlier versions it was kind of possible to adjust the clutch though, so with the latest and greatest SRAM has to offer when you get chain slap it's pretty much had it.

im not a sram user....but how long do their clutches typically last?

obviously depends on the service its doing....but i know no one thats had to replace one.

The PB review said they ran it for 6 months without ever making an adjustment, and that includes a crash or two.
I think the whole idea is there are no more adjustments. I may have misunderstood, but I don’t believe there is a b screw or limit screws so I don’t know what would even be adjusted.

The true test will be when the public gets it on the trails. Someone will find a way to make it fail, and it seems like it will be catastrophic when it does. That being said, it looks like a superior design in about every way, the price is absurd but so is eagle AXS. I am mostly curious if they ever produce replacement parts where they are actually available.

@Branmuffin AXS has limit screws and B set screw and of course there's an index adjust.

But once you've set up a derailiuer there's no need to do anything really, unless the cable stretches and then the indexing needs adjusting.

yeah, ive seen the reviews and its impressive, no doubt. I only adjust my drivetrain maybe once a year....some bikes nothing. some bikes ive had to replace many hangers....very curious to see what parts are replaceable and the cost.

but like you said, the sample size is small. i am all for parts that last longer, but yeah....not for that price for me. I'm also not a huge fan of dealing with batteries so that's already a downside for me personally. i already have enough to forget about.

I believe Branmuffin was discussing the NEW Sram transmission system. There is no B-screw on it and it never required any adjustments.
Check out the PB article.

Seems pretty amazing, but too expensive for me.

@BenLow2019 thanks for the info, just had a dig around to find out more.

Seems at least with it there's still an indexing feature of sorts with micro trim, but it's really sparse on how limit could be adjusted.

At a guess it may be an app that's used for that.

No limit to adjust by my understanding.
Since the new derailleur becomes one with the UDH standard frame and the wheel axle and it's mated directly to the cassette - mind you it only works with the SRAM branded cassettes - then it's bolted on and ready to go (if you follow the installation instructions correctly). A minor index tweak may be necessary through the app and it's done. No limit screws at all. AND the derailleur is supposed to be repairable too.

I really dig it, but wish there was a regular cabled version. I'm not a fan of having to charge a battery every ~20 odd hours to ride the bike. Then hoping the battery or electronics doesn't just die anyway. The reviews give the durability high marks which is really encouraging anyway.

your understanding is correct. the way this was engineered is with a UDH dropout. with this being the origin for everything. sram knows exactly where the 1st and 12th cog sits because of this.

batteries are the killer for me....but mostly the price....the cheapest one comes at 2300CAD...i can replace my derailleur more than 10x at that rate. incl the hanger...i can use a lower or higher end model if i cant find my current RD locally, i can keep a spare when im travelling without breaking the bank (arguably, you wont need to keep a spare with this new system)

for me, the cost does not justify the pros of the system. and realistically, price may be the only con of the system. would love to see the numbers on how many break

Hey
Is XX X0 crankset compatible with a EAGLE XX1 8 bolts power meter?, what about the chainring, can I use a CR-TTYP-104-A1 chainring to match the t-type chain??
