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.

The Fox Float DPS rear shock on my 2020 Occam started leaking oil on my ride yesterday. I bought the bike used and I doubt the shock has ever been serviced. I’m 50/50 on whether I’m going to keep the bike, since I feel it’s slightly too big.

What’s the move? Send the shock in for service and then sell the bike? Upgrade the shock and keep it?

I have a 170mm boost sram(truvativ) dub crankset and I as going to drop to 165. There are some good deals on sram superboost cranksets. Is it possible to use some of my existing crank parts to adjust the chain line on the superboost? Or not worth the hassle?

I’m gonna add to this question. Is the 165 sram crank just drilled shorter than the 170 or is the 165 actually a shorter crank arm?

My 165 SRAM DUB GX cranks are just drilled shorter. Old 175 crank boots don't fit...

DONE!

Canfield cranks are shorter arms. I've had them on my Rail for a few years, been pretty happy with them and decent price. Not light weight though. I went with 160mm to get fewer pedal strikes. Wish I'd gone even shorter to 155 or 150mm.

The SRAM AXS worked pretty well for chain length on my new Transmission serum.

Any comments on how well it correlates back to normal Eagle? 1:1, or some set number of links less or more?

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

Currently doing a rebuild on my Code RSC levers (have a partially stuck lever and the contact adjust wheel isn't spinning). Sram says you can use either DOT fluid or DOT grease on the new lever piston. It got me thinking, is one more ideal than the other? DOT fluid feels like there would be less friction, but grease might offer smoother, more reliable/durable movement? Anyone tried out both methods and have a suggestion?

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?

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.

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?

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.

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?
