SRAM GX Eagle Transmission Review Update

They've changed the direct mount chainring interface by the looks of it which is a pain.

You don’t get the Magic Pulley

It does feel like a gimmick anyway. Plus, as I now have a bike that will accommodate T series, a story about new GX AXS is still not helping in my quest to not buy AXS. I'd appreciate it if you never speak of this again. Thanks.

That crankset is ugly. Otherwise, looks like a decent groupset and I see no reason to go with anything higher.

8 bolt ones have been around for a while on their road kit, but yes, the 3-bolt system didn't seem broke

They've changed almost everything - flat top chain with the bigger rollers means cassette incompatibility too. I mean, it's now compatible with the Road stuff, but other than locking everyone in to them I really don't know why they had to fiddle with the chain.

The 8-bolt thing is apparently to accomodate power meters

They’ve changed almost everything – flat top chain with the bigger rollers means cassette incompatibility too.

Isn't cassette incompatibility a given as "T-type" kit is spaced wider?

presumably the 12 speed cassette spacing is always the same? just the 'start - finish position trim' changes?

Dunno...i'll look into that...

I'd hapily try one of the t type derailers if that's ALL i need to buy... I've got a shifter/chain/cassette that are fine!

I thought part of the reason they did it was that by dictating exactly where the cassette and derailleur are in relation to each other they could effectively use that last few mm of dead space between the cassette and the dropout? i.e. the bit of a boost hub that used to measure 141mm (excluding the bit that sit inside the dropout) can now be slightly wider as they don't have to allow for frame designers doing their own thing with dropout shapes.

Massive reductions in price by the new year do we think? That's when I'll pick it up, minus the cranks.

So will Salsa be able to produce an Alternator dropout for this?

Those cranks (and to a lesser extent the rear mech) make it look like a Duplo Transmission to me 🙂

At £1180, I’d say it’s almost reasonable enough for me finally to make the jump across to electronic gearing. I really want to. But having to buy a new frame to hang it off?

Sorry SRAM, but I’m out.

Surely you can pick up a full GX AXS groupset for less than that without having to resort to the new version?

I've got a compatible frame, and think that when my chain ring and cassette go, I'll be upgrading.

The idea of not having to keep replacing derailleur hangers and shift cables is very tempting.

reckon around £600 with some deal hunting. Upgrade kit is sub £400 on sale, cassette & chain ~£200

Have they done anything to fix the lag between presssing the sifter button and the electronics deciding it’s lined up and will actually shift gear. There are loads of videos showing how much slower T type AXS shift compared to normal AXS that none of the journos are commenting on for some reason

It's mentioned by Ben in the write up above.

thats what i am hoping too!

I have sliding dropouts

The GX AXS is an option, yes, absolutely. But how long are Sram going to support it, given they’ll be wanting folk to go for their flagship UDH system?

I’d say that there’s going to be decent market for non UDH derailleurs for quite some time yet.
