Introducing the Telum.
Struggling to get your suspension feeling right? Unsure if it could be better? You're certainly not alone!
In fact, very few mountain bikers are truly satisfied with their suspension setup - especially on stock OEM equipment.
That's why we developed the Telum - because getting suspension right is our job, not yours.
The Telum comes Ready To Ride, fully customized for you and your bike, including:
- The appropriate rate-adjustable Sprindex spring
- Customized valving based on your personal requirements & bike kinematics
- Personalized adjuster setting recommendations
- Reducer hardware for your frame
All you need to worry about is where to ride next.

A mountain bike shock like no other, the Telum is truly unique, and jam packed with every imaginable feature:
- Hit the ground running from the best possible starting point, with our customized Rapid Revalve tuning process delivering you personalized valving AND recommended settings, unique to you and your bike.
- Balance out your rear wheel small bump compliance and chassis control with 18 clicks of low-speed compression adjustmentÂ
- Dial your shock in for the big hits with 12 clicks of high-speed compression adjustment
- Tune your bike's on-trail feel with 18 clicks of rebound adjustment
- Zero in on the perfect amount of bottoming resistance with 18 clicks of hydraulic bottom-out adjustment, active over the last 15mm of shock stroke.
- Save your shock - low-profile polymer spherical eyelet bearings to eliminate sideloads, prevent corrosion, minimize weight, reduce friction and reduce wear.
- Save your frame - our exclusive self-centering eyelet reducer hardware prevents shock-to-frame contact by limiting the range of motion of the spherical bearings.
- Save your legs - with a firm lockout mode for the long climbs
- MSRP $1600CAD ($1200USD), including spring and reducer hardware.
- Available in all standard metric strokes from 47.5mm to 75mm
- Available in trunnion and standard (spherical) eyelet
- Shocks will begin shipping first week of June, 2024.
Quantities of the Telum are very limited as demand is currently exceeding supply.
This means the typical lead time from placing your order until it ships is approximately 3 weeks.
You can secure yours with a $200 deposit. We will send you a payment link for the balance once your shock is built, ready to tune and ship.
After ordering, please ensure you register & fill out a tuning form on the Vorsprung Tuning Hub. We'll use those inputs to tune your shock for you.
The Telum is tunable for almost any mountain bike, using any leverage rate curve out there. It's built to fit within a similar envelope as competitors products such as the Fox DHX2 and the Rockshox Super Deluxe, but there are differences too.
The chart below is constantly being updated. Some frames will physically fit the Telum, but are currently incompatible due to excessive yoke lengths.
Custom tuned for YOU.
Facilitated by our exclusive tuning software and our patent-pending Rapid Revalve system, your Telum will arrive custom-valved for you, your bike, your terrain and your preferences.
It will also arrive with the appropriate spring, the correct mounting hardware, and your personalized recommended starting points for the damper adjustments.
The Telum isn't our shock... it's your shock.
FAQs
Where do we start?! The Telum is like nothing else you've seen on mountain bikes before.
The solid main piston means that unlike conventional shocks, no oil flows through the moving piston of the shock.
This means that all damping duties, including lockout, can be handled in the reservoir bridge - where our exclusive and patent-pending Rapid Revalve system is housed.
This in turn means that the shock valving can be set after the shock is built.
The polymer spherical bearings also isolate the shock from side loads, whilst being lighter and not susceptible to corrosion or noise like conventional metal spherical bearings.
Of course, all the niceties like LSC/HSC/Reb and even HBO adjustments are included, so you can tinker to your heart's desire should you want to explore what the Telum can feel like.
Ultimately, because Rapid Revalve enables us, and our dealer network, to put you on a better setup in under 5 minutes. Conventional shocks need to be disassembled, re-shimmed, reasssembled, rebled, recharged with gas, and cleaned in order to fundamentally change the gradient of the damping curve across all speeds without either introducing (or altering) preload to the valve mechanism, or introducing/altering free bleed. This is a time consuming and expensive process, and opens up more opportunities for human error.
Rapid Revalve circumvents this entirely, by allowing any trained technician to easily change the fundamental stiffness of the shim stack without the need to disassemble, rebleed, repressurize and clean the shock. Rapid Revalve is also tolerance-insensitive - there's no clearance or float issues that require expensive tools and full teardowns to adjust, nor the inconsistencies that arise from trying to maintain low/zero float with low/zero clamping force.
This innovation allows for true personalization of the shock at the point of sale with ease and consistency, rather than "custom" tunes being shipped from the factory into the void with the hopes that it happens to line up with the rider's needs. On a technical level, Rapid Revalve also automatically sets the range of the adjusters in proportion with the valve stiffness. Just because we could.
The majority of "custom" tunes out there, both OEM and aftermarket, are mostly or entirely based on your frame's kinematics, because they're usually generated with no knowledge of exactly who the end user is. They have to assume you're the average rider, of average strength, riding the average terrain, and that you're of average weight, with average preferences, or preferences that happen to align with the team who developed the tune, even if they have unusual preferences themselves.
By contrast, the Vorsprung Tuning Hub generates spring rate recommendations, as well as damper tune specifications and recommended settings for the Telum according to every single unique bike/rider combination. It takes into account the objective factors, such as rider/bike weight and leverage rate curve, as well as subjective factors - such as your terrain type, how hard you ride, how strong you are, whether you're hitting big jumps, and simply whether you prefer a softer or firmer setup.
We also encourage you to upload a short video (a 10 second Iphone clip is fine) as that helps us gauge your riding and terrain a lot better than text.
You can! As a Telum owner, you'll be able to use the Tuning Hub view your shock's tuning data including the tuning history of your shock, what frame and rider parameters it's tuned for, the recommended settings, and the damper curves that result from that.
At this time, it's only our trained & certified partner network who can use the full-featured tuning side of the Tuning Hub to determine valving specifications.
If you'd like to make changes to your own shock's valving, please email us and we'll put you through the same training our dealers get.
No problem! We'll change it until you do like it.
Our Tuning Hub can determine spring rates in a few different ways:
- You can rely on our recommendation, which will calculate the most appropriate spring rate for your bike in order for you to be able to use all your travel appropriately, and it'll calculate the sag for you from there.
- You can specify a preferred sag percentage (if you know exactly how much you want)
- Or, if you've already got a coil spring rate that you like on that bike, you can tell us what that is, and we can work with that.
On top of that, Sprindex springs allow you to adjust the spring rate by around 10-12% (eg from 450-500lbs/in) to maximize the chances of you getting exactly what you need.
However, mountain biking is a very personal thing when it comes to preferences, so if you find the spring we've recommended for you is too firm or too stiff, let us know - we can get you a sizeable discount on a replacement spring. We don't offer exchanges though, sorry.
We get this kind of request fairly often.
Firstly, which damper curve would you like to see? There's well over 1000 of them in the Tuning Hub.
Secondly, how do you determine from looking at a 2D force vs velocity curve which shock is "better" than another, without all the rest of the context required?
It's not possible to make that claim with any validity, so we don't.
A claim we CAN back up though, is that our tuning process is more thorough and more personalized towards your specific application than you'll find anywhere else.
First, check the Frame Compatibility tab above to see if we've already confirmed fitment.
The Telum was built to fit a wide range of mountain bike and e-MTB frames and mounting systems, however there are so many frames with unique clearance concerns and so many unique shock mounting systems on the market that we know some will not fit, however we have not yet checked every frame out there.
Please email us directly with any questions regarding frame fitment - if we don't already have an answer for you immediately, we'll work with you to find out.
It means you can easily custom tune suspension for your customers with no guesswork, less hassle, and less risk than ever before.
You'll need to set up a dealer account with us and complete a 15 minute online training course that runs you through the process first, then you're good to go.
If you haven't already checked the fitment chart to see if we've already checked it, check out the 3D CAD models and Frame/Shock Interface Design Guide HERE.
The Telum is approved for e-MTBs as well as regular mountain bikes. The same compatibility limitations apply with respect to yoke length. For more information on frame compatibility, please check out this document HERE.
