Fork and Shock

It works on all fork systems and the majority of shock set ups. Get your mountain bike fork setup fast and make shock tuning easy.

Air and Coil

The SMB Flow works just as well, with both air and coil suspension systems.

Here's how it works..!

Attach the SMB Flow to your fork or shock – it works on both air and coil. It’s really easy to attach, just a few straps and you’re good to go (putting it on your fork takes less than 2 minutes!).

Then just put in a couple of details into the app and you’re good to go. And the best bit…your phone DOESN’T need to be connected to the SMB Flow while your riding. Just reconnect when you’re ready.

Next, go ride your bike like a demon!! The SMB Flow collects data during your ride…if you’ve not collected enough (it’ll tell you), that’s fine…just go ride some more. Collecting ride data is the fun bit!

The Phone App recommends adjustments to the damping on your compression and rebound – and works for low and high speed settings too! Simply adjust your settings and do another ride to check how dialled you are. If you need more adjustment, just repeat until you’re suspension feels sweet!

Now your suspension is feeling super sweet…go SHRED those trails!

More control. More fun. Less pain!

Here's some questions we've been asked, that you might want to know the answers to...

Why not just use my judgement?

You absolutely can use your judgement.  Bikers have been doing it for years, but trial and error can be a long and frustrating road.  The Flow takes the guesswork out and takes multiple inputs into it's algorithms to work out your recommended adjustments. 

Will it work with my bike?

The SMB Flow works with almost all kinds of forks and shocks - and both air and coil systems. So it likely it will. Unfortunately we can't control all the designs out there and we know that it can't currently fit fully enclosed shock systems. If in doubt, just drop us a question (either on email at or try us on LiveChat).

How do I use it?

It's designed to be super easy to use. Simply attach it to your fork or shock, open the app, enter a couple of essential details (e.g. the length of your travel) and start your session. When you've hit the trails, you can check your analysis and recommendations. The more data it gets, the better the recommendations, so it you need to go shed a bit harder, the SMB Flow tell you. Then it's simply a case of making the adjustments and feeling the difference.

Do I need to keep it connected to my phone?

Nope. Once you've started your session, you don't need to have your phone connected - so you can leave it safely in the car if you want (although we always take our phones in case we crash out on a run).

How long does the battery last?

Newly installed batteries can last over 100 hours of use.  However the Flow works at its best with a well charged battery, so we recommend changing them after 48 hours of use, to get the best out of it.

Is it waterproof?

It goes without saying - it was invented in Scotland, afterall!

What if it's broken?

Sometimes things go wrong! If the SMB Flow is broken or malfunctioning, then we'll happily fix it or replace it if it's not fixable. Check out our returns policy for more info.

I have coil but Shock wiz can't measure it, can yours?

Good news, yes! Unlike the Quarq Shockwiz, we don't use air pressure to gather data, so the SMB Flow can work on coil and air systems.

I've a hardtail. Do I still need to fine tune my mtb fork?

Whether you have a full suspension mountain bike, or a hardtail, fine tuning your suspension is vital to how well your bike rides. We believe in it so much, we're starting a blog to teach riders what they can do to improve how it all feels.
