This is what I use for 2 bikes on a 1up rack. Restaurants. Grocery stores. Trailheads. Overnight at hotels. If I have more bikes, I’d rather get a second chain than a longer chain. It gets unwieldy. I think a 1/2” chain would be too heavy and cumbersome at this length.
Is it infallible? No.
Do I have insurance? Yep.

Then look for a lock that the Lockpickinglawyer doesn’t single out as totally sucking. Like, don’t get a MasterLock. And don’t get something smaller than the chain or you’re paying too much for the chain. Budget $25-40 for a solid lock. Double-Triple that if you just want to buy a bomber lock and don’t have patience for the padlock rabbit hole.

I was debating this same thing and found this "Home" style lock from Hiplock on sale. https://hiplok.com/product/home-silver/ With the code meg20 it was just over $50 shipped. I will report back when it arrives, but I figure I will use this heavy ass thing only when I have to leave my bikes overnight, unattended for 1+hr on my car or in my shed long term.

Found this on the trail today. Looks like an insert for a fork. Like a Runt, but not a runt. Anyone know what it is?

Is that one of those dumb Carbon things?

TruTune? They look different from google pics.

Yeah, none of those things. It's a mystery, it's not threaded, it has an o ring. Doesn't appear that I can take it apart. I can't put weed in it... looks like a schrader valve, but I can't depress it nor put a pump on it. I am gonna lose sleep now.

[SchralphMacchio]

Looks more like a DC barrel jack power connection than a valve. But no obvious indication of what it does …

If you plug it in, does it vibrate?

Just went through the Eagle setup video for chain length yesterday.
They recommend 1.5 links overlap for FS, 2 links for HT.

My bad. The word «app» was missing.
The AXS app gave me perfect chainlength for Transmission.

I know the SRAM video, and it has worked well.

What I wondered was if it was a difference between chain lengths for Transmission and normal Eagle. And if there is; why? Has to be the dimensions of the derailleur if frame/chainring and cassette is the same, no?

I don't think you could say for sure the derailleurs in the same place, with the same jockey wheel sizes and spacing.

The transmission derailleur doesn't pivot on a hanger mount or have a b-limit adjustment so yeah the chain has to be a very specific length for it all to work, where any other derailleur has a little more room to fudge it. Non transmission, as long as the chain doesn't go slack in the hardest gear or rip the derailleur off in the easiest gear and you can get the b-limit adjusted relatively properly then it's probably fine. Which, I guess short answer is yes you could likely use transmission calculated chain length on a regular eagle drivetrain but you'd definitely want to check it on both ends of the cassette.

Do I want a 100cc Oneup pump or the 70cc? I might buy the tool too but can't see myself keeping an CO2 in there unless that's something I should be doing?

[rideit]

I don’t find the 100cc to inflate particularly quickly, as such, I probably wouldn’t love the 70.

[GBB]

Air can services can be pretty darn easy. So if you’re feeling cheap go that route.

Or just have your LBS service and talk for with them at the same time.

Then choose if you want to sell the bike.

This was the move. Thanks. Simple air service took care of the issue.

I only get a flat every few years or so (knock on wood) so I just got the 70. I don't keep it on my bike usually, just throw it in the pack when I go on big rides. I keep a CO2 in it to compensate for the pump size. I figure that if I do manage to flat, I'll try plugging it and the pump first, and if the plugs seem to work, I'll use the CO2 to finish filling. If they don't, I'll throw a tube in, and use CO2. It does take a very long time to fill up a 29"x2.5 tire.

Anyone ever done a Hall lock modification to an AXS derailleur? Does it help resolve the weak clutch issue?

Which derailleur? My X01 feels a lot stronger than the GX upgrade kit I had on a different bike. Don’t know if it’s the same clutch or if some internals can be changes?

Thanks. Makes sense.

The app gave me the number of links I had on a slightly used chain, so it was tempting to see if the app could be used. But «the method» gave me 2-2,5 links overlap and when mounting it was too slack, so I guess you’re right

That may be true but my XO AXS is a lot weaker than my cabled XO Eagle derailleur and even cabled GX. I get a lot more chain slap vs. cabled XO for sure.

Never heard of this until now, gonna try to figure it out. As mentioned, the clutch on my XO AXS is noticeably weak. The chain slap is pretty annoying because I've taken measures, and everything else is whisper quiet, especially with Onyx hubs. It's pretty awesome to me to just hear the tires biting on the dirt.

Curious as to any AXS derailleur. I've only run an XO AXS briefly - shifting was good, but the clutch was useless and chain management was a mess. I switched back to cabled XO1, which works fine in terms of the clutch, but my frame has shitty cable routing which leads to shitty shifting, so I'm back to investigating wireless. But I'm not gonna shell out for AXS unless I can find a way to improve the chain management. So I'm hoping someone has experimented with doing a hall lock on an AXS derailleur and can comment on whether it made things better.

Nice - let me know what you figure out.

I believe Sram put weaker clutches in the AXS derailleurs, supposedly to improve battery life (so the motor isn't fighting a strong clutch on each shift). But it makes for a lot of chain slap, and at least for me, a lot of dropped chains.

I still run an MRP SXG on the Enduro bike like Dude in the video. Top and bottom guide, no idler. Never dropped a chain with it.

I've got a top and bottom guide too (they're stock on the Norco Range). Still dropped chains with the AXS derailleur - 3 times in a weekend. I've never dropped a chain with a cabled derailleur on that bike.

And dropping a chain with the guides sucks - I've gotta unbolt the guide to get the chain back on.

Anyone remember that contraption from the 90’s, that had an aluminum ‘arm’ that stuck out above and behind the derailluer, and attached to the pulley cage with a spring?
I can’t seem to find a reference to it anywhere, but it was definitely the first anti-chain-slap derailleur device..,

You’re killing me, I can see it in my head but, but can’t for the life of me remember the name!

Thanks, that was driving me crazy.
