believe the hype, the simple fact of the matter is this device has transformed my 38s, I have 2 pairs one at 160mm on my Levo and a set at 180mm on a kenevo. the difference with the Levo is good, sensitivity to bumps is improved and overall grip is much better I dont hammer this bike but is well better with the flow all day long. BUT... I feel like it rocks sox on the 180mm best. it's day and night when comparing this fork with tokens in. all I'll say is do it, just go get one you will NOT take it out. ive a set of 2023 36 factory arriving this week and I will be definitely be ordering the flow & the hit device if fitting permits. and the dust cap at less than £6 is a bargain very well made. the flow device is very very very easy to fit.

Such a noticeable difference at park, pump or trails. Once the Hit has been released I shall be getting another!

As I am a big bloke, I have to run high air spring pressure to get the required sag, my fork though capable, doesn't have any of the whistles and bells of the higher spec'd forks in the Fox 38 range, using a higher spring pressure results in very little small bump compliance, this is what I miss the most as I don't tend to throw my bike off anything higher than 30cm.
I'd seen some positive (though not a lot recently) reviews of the Trutune insert, and for the money, a lot cheaper thank potentially changing my forks.
I ordered one and fitted it straight away, using Trutune's setup advice, retaining the already installed token and increasing the pressure by 15% to get the required sag.
I can only say, what a difference! really compliant off the bottom and better mid-range, I will probably remove the original token as I'm not a particularly hard rider and the forks are nowhere near full travel.
Money well spent!

Rides higher, creates grip, easy to install, turned a basic Domain into a much better fork on my ebike. Confidence inspiring. I'm clearings drops and jumps with added height I think due to the way the TruTune Flow makes you ride higher in the suspension. This thing is REALLY good.

I tried it just because I was curious, and I liked it since the first descent. I followed the instructions, so no bottomless token and only the Trutune for a XC/DC use, a little bit more air pressure and the job’s done. Feels super nice on small bumps as well as bigger rocks, and the red ring on the fork speaks clearly about how much more travel is used (at least 8 mm). I’m very happy at tue moment, and hope it’s going to last a lot.

Trutune fork insert, I'm a 70kg rider, running Fox factory 36's on a Specialized Levo, but wasn't getting full travel, even without any tokens and sag set to soft.
The carbon fork insert has cured this issue, plus:
Initial movement is as smooth as a coil fork off the top.
Stutter bumps and trail chatter are reduced dramatically.
Front end grip has improved by about 10%.
I set my sag half way between firm and soft, according to Fox.
I adjusted the compression and rebound setting as advised by Trutune, then fine tuned them over my next ride. Left rebound alone only reducing HSC and LSC by one click.
As I didn't suffer any noticable bottom out, I increased the sag to soft and it was perfect.
I had held off purchasing for a while and I now wish I'd just taken the plunge.
For me this is a game changer.

I believe that think should work even if you don’t believe in it , it’s work , it’s make great upgrades to the fork

I bought an older (cerca 2019) Rockshox Lyrik and I added the Tru Tune and it feels better than all the newer forks I have tried. The increased control and feel is amazing.

Rockshox Lyrik Ultimate 160mm

This thing works so good! Best upgrade for your fork! Wish I bought it sooner.

I was able to demo a friend’s for a couple of ride’s and it was an eye-opener, night & day difference. I ordered one asap for myself & upon arrival, I immediately installed. Now, I’m awaiting the current trail conditions (Winter) to improve before initial shake down…can’t wait. Keep up the beyond great work you guys do!

So I felt I was not getting enough support mid stroke , I was already running one token so added another and felt two was to harsh and suffered a loss of grip up front.
So trutune looked to be the answer and I pleased to say so far it's working as expected great small bump sensitivity and great mid travel support grip was improved as well.
So I'd say a great product that does what it says . Best advise I would give if you are thinking of getting a trutune is to properly understand what it does so you feel disappointed. I knew what was wrong with my set up and researched alot of products.
Grip increased by 10% i would say and fork support 25% increase which in my eyes is a great improvement.

Added this to a set of Fox34 Step cast forks. I’m 72Kg. They have been great since. I’ve been able to add at least 10 psi and get full travel. I’m now at 75psi and zero tokens and the forks are really plush.

Great product for the price. Ordered two, one for my Lyric, and the second for my Zeb. I ordered the one for my Lyric (160) for better small bump and mid stroke support. I ordered the second for my Zeb (180) to get full travel and better small bump compliance. The product achieved each of my goals tor my different forks. Still playing with air pressure and tokens but that is a personal problem.

I have found the flow definitely makes a difference using more travel when needed and less tokens required. HSC pre flow I’m -1 to -2 I’m now central on 0. Again LSC pre flow I was more or less fully open on the -, now I’m more to -5 clicks. Rebound I’ve been generally 1 click slower though faster riding I’m back where I was before which is 7-8 clicks from full slow.

I bought this for my new 180mm ebike. I’m a 6’2” tall and 125kg full riding gear. Running high pressures usually means a harsh ride or tokens and lower pressure but can lose some mid stroke support especially on the steep stuff. Trutune allows me to have great support but also use all of my travel (180mm) when needed!
