Hello Vital MTB Visitor,
We’re conducting a survey and would appreciate your input. Your answers will help Vital and the MTB industry better understand what riders like you want. Survey results will be used to recognize top brands. Make your voice heard!
Five lucky people will be selected at random to win a Vital MTB t-shirt.
Thanks in advance,
The Vital MTB Crew
Duck tape, a stick and a helper with a tape measure will be good enough.
What a time to be alive. Unbound opulence.
Kids, make sure you understand the gradient of the trail you are riding that day too so you can make sag adjustments based on likely weight distribution changes due to gradient variances. Spend 1-2 hours on bike setup/prep. Ride ~4-5 laps of 3-5 minutes each (total ride time 12-25 minutes). Spend 2 hours analyzing data, posting strava, posting grams, posting trailforks, posting youtubes, arguing with netbangers. Sit back, soak in all the WINNING.
This is TRULY what peak cycling enjoyment looks like.
It’s the rocks to the bottom of my SXg that’s usually my limiting factor LOL
While we’re on the topic of suspension gimmicks, is there anything in the vicinity of System 2 from Motion Instruments?
BYB is too expensive for how I’m bumbling down the trails, and Shockwiz doesn’t work on my bike (Öhlins fork and coil shock).
Don’t think anyone near me is doing rentals or setup days either.
System 2 would have been perfect in terms of ease of setup and relatively low price compared to other options but never came to be.
Not sure I wanna watch this. Dave's voice saying "IT DOESN'T MATTER" about weight on one of his other vids from a few years back still rings in my head!
It does matter a little for me as much of my riding in the summer is long rides for long descents at10k feet + elevation. But his voice is there reminding me to not sweat it too much.
If I watch this vid, am I gonna be stuck with some other thing in my head about sag?
Use percentage of wheel travel instead of shock. He’s the euro distributor of a $350 tool.
That’s pretty much the whole thing.
I think this device is Nice! Its pretty easy to do and If You want to Setup the Bike with more weight(Winter/ different cloth helmet) then its so easy to do IT with this device! And the Option to Check the bushing Play is also realy cool! Yes there are Other ways to Check it but i think this gives You a good indication how bad it is. but yeah He is pretty confident about it 😁
How do you choose which words to Capitalize and do you by Chance wear googles around your neck while wrenching?
Yes
And I thought he did a video saying weight was super important, or maybe that was just lightweight wheels and xc tyres at 30-something psi, and the rest of the bike weight didn't matter?
@AG Pennypacker - it doesn't matter what tyre you use when you pump them all up rock hard!
This 1000%. Sag is a nearly useless measurement for anything other that a very initial baseline for setup on a new bike. Depending on the kinematics and dampers involved you might be anywhere from 22-32% sag between platforms with an optimum setup.
The real question is not if we are measuring it correctly but if we should we be measuring it at all 😂
Sorry but english is Not my mother tounge. And grammar is also difficult for me! But Nice that You think that you are a better Person or You are smarter because your grammar is on Point. My Phone dose also some auto correction which makes it worse. In contrast to You i wrote my Personal opinion about the device!
Hard to trust somebodies judgement when they are wearing all white mountain bike clothing doing measurements with goggles around their neck.
I have the DRC tool for measuring sag on my moto while solo. I think these are still too much money, but it's a lot better than the $150+ for the Slacker tool. Accomplishes the same thing and is $40.

Agreed on all counts. If it's repeatable, it's as valid as it can be, but it's not a very meaningful target in itself, it's a byproduct of having the necessary spring rate for the loads you put on the bike and the ride quality you're looking for. Worrying about the precision of the sag measurement like that is utterly pointless if you're ignoring the factors that actually matter when selecting spring rates.
On that note, we have a few different ways that we calculate spring rates for the Telum on any given frame (tuninghub.vorsprungsuspension.com) - if you know what you want already, you can tell us how much sag you want, or what spring rate you prefer if you already run a coil.
However, the default way we do it is actually to estimate how much force you're able to put through your suspension (based on your weight and how hard you ride, what kind of terrain you're on, how big you send it etc) at a point very deep in the travel (not quite bottom out because some frames do whack stuff at the very end of the travel that's better to ignore for the sake of ride quality the other 99.9% of the time). Then we work backwards to work out what spring rate that requires, and how much sag that gives you as an incidental outcome of the spring rate that's necessary for you to be able to use your travel effectively. On some bikes, that might mean you're at 25% sag, others you might be at 35%. This is due to the characteristics that are designed into the frame's leverage rate that mean you can't necessarily translate sag figures from one very linear or even falling-rate frame to a very progressive one.
There are other ways to do it too, like using the spring energy storage, but there are some limitations to that particular method insofar as being heavily affected by the progression prior to the sag point with certain leverage rate curves. Natural frequency can be used too, but it doesn't translate particularly well between different bike travels because the whole point of longer travel is softer springs (lower natural frequency) and it doesn't do anything to account for bottoming resistance or travel usage.
what a co-incidence, the other site has an article on exactly this topic lol
Love that the two top guys in the squish world replied here and not on the other wise. Vital superiority
Motion Instruments is done.
BYB V3 is the next option.
If only it worked for bikes with shock tunnels. Looking at you Forbidden…..
I start most endeavors with the assumption that I'm doing it wrong.
His video convinced me otherwise.
