Question for the experts - have any of you done a home service on a Rockshox Charger 3 damper? I bought the $75 kit to convert it to Charger 3.1 and am contemplating whether to do the service myself or send it in.
In terms of comfort with the job, I've done as far as bleeding a Charger 2.1 damper, but have never done a full tear-down. Looking at the service manual, there are a few steps and parts, but no proprietary tools. For those who have taken apart a Charger 3, do you recommend I give it go? Is there anything that's easy to mess up (other than dropping a small part on the floor and having it disappear)? How many beers job is it?

My brother bought a used bike with an X2 that shit itself pretty quickly. Filled out a service request from Fox since shock was out of warranty, mailed it in to them and paid the $170 for service. Got a brand new 2024 one sent back. Anecdotally, I've heard the changes in the latest version do fix the self destructive nature of the X2.
I've got SDUs and Vivids for both my pedal and ebikes. If you're on roots a lot, I'd say the Vivid is worth it. In deep travel they feel pretty similar, but the Touchdown tech on the Vivid damper is really special for small bump. Basically it's position sensitive damping, where the first 15% (?) of shock stroke have the damping full open. SDU is a nice poppy shock that I'd favor for flow trails or trying to weight weenie (it's 200g less for same size).

I just got that kit and was going to do it in the next few days. I'll try to remember to say how it goes. I've never worked on a shock damper, but I did damper surgery on a pair of Super Deluxes a few months ago and it wasn't difficult, so this looks comparatively easy as long as I have the instructions in front of me and take my time.

I have warrantied two x2s in the past 6 months with that exact description, no further damage or oil leaking externally needed. They just sent me a brand new 2024 version. Not sure where you are located, but a previous thread made it sound like the west coast Reno service center was a lot more laid back about it than the east coast one.

Been on sale for a while, so I was beginning to wonder. Mezzer has too, like a year. Guessing they’ve got an upgraded Mezzer coming out as well but they’re taking their time. So much so that they have 44mm in stock again, which is making it nearly impossible not to order one.
Remind me. We'll send him a red cap and a Speedo.

I had my offering setup with 160mm fork as well so…

2015 called and asked for their question back.
Seriously, just stick tubes in there. It’s a gravel bike.

Tubeless works great on gravel bikes… maybe more important than mountain bikes (maybe not when remember getting 2 flats per ride on 26” wheels with tubes) but to the actual question….
Rim and tire spec matters. There are big variations in tires. You could choose some tires that have a tight fit and call it a day. The hacked version is to add .5-1 more wraps of rim tape. This won’t help them hold pressure initially though.

I did it last night. It took about 3 hours but I did get interrupted in the middle to cook/eat dinner. I didn't think any of it was especially technically challenging, but I do recommend having the instructions printed out to follow along. There was one point at which I started to reassemble part of the compression damper backwards, but caught it quickly and only had to backtrack a couple steps. So, it wasn't hard but it was time consuming. If I like the 3.1 and decide to put it on my other bike's fork, I may just get the complete assembly to save time, since it's just drop-in.

So I just went back to the trusty gorilla tape method with two layers. Actual rim tape too thin. Shakeout ride this AM and I think she is good to go again.
Tubeless at 50psi+ on a steel gravel bike is a dream honestly. I used to run tubes on this same bike for like 1 day and it was WAY harsher.

These tires are rated up to 60psi. All the gravel here is accessed by pavement anyway. To just ride gravel you gotta drive out somewhere and then park. I'm on gravel after a mile or two of pavement from the house. I have run lower pressures and it just feels too slow to me.

I think the standard argument when people claim that lower pressures feel slower is just that you're not feeling your fillings rattling out of your teeth. All the bro-science would indicate that lower pressures are proven to be quicker as long as you hit the sweet spot. Faffing around with the Silca pressure calculator led to me trying some dramatically lower pressures than I typically would have and I was pleasantly surprised. That said, do whatever damn well please. Its just bikes.

Hmmm, the calculator said I should be at 42/40 psi. I've been around 50-55. Might have to experiment.

I think that’s about right: it might feel slower because of the smoothness, but if you had a power meter and a speedometer you’d see improvements over the same terrain.

When you guys replace a spoke, do you jut cut a hole in the tape and then “patch” over it with a bit of tape? Or do you pull off all the old tape and start over?

I started in the mid 50s on my gravel steed and a buddy who spends a lot of time out told me to drop that shit. Running 35 to 40ish depending on terrain now but even on pavement the comfort gains vastly offset any loss of efficiency IMO. Makes it possible to bunny hop stuff without fearing for your C-spine.

I know nothing about gravel tire pressures, but world cup XC guys run around 15 psi, and those tires aren't *that* different than gravel tires. If higher psi was faster, those guys would definitely be running higher pressures. It's not apples to apples, but it's at least apples to some other apple adjacent fruit.

Step 1: Go to Silca Calculator and input your specs
Step 2: Find out that you should be running pressures much lower than you thought
Step 3: Do it, and go ride
I and others have likely found out we should be running lower pressures. Give it a shot.
I run 60 psi in my 32mm road tires, 42 psi in my 40mm semi slicks, 34 psi in my 48mm gravel tires, and 28 in my Race King 2.2s. For reference, I'm 175 lbs

Eating crow about my Kryptotal and on a roll with dumb questions: I cannot keep air in my front tire. It's losing at least 10lbs/24hrs. Not a fast enough leak to lose air while riding but still kind of annoying. I've tried adding sealant twice to no avail. Going to try breaking and reseating the bead, are there any special tricks to get it to seat properly? I typically use an air compressor to do the job. It's like I got 99% of the way there... But just short. Failing that, is there any way to troubleshoot a valve core short of just sticking a new one in?
