I installed one of these to my 100mm Rockshox sid 35’s and it’s transformed them, I now get full travel and the small bump control is a night and day difference. I’ve got a second bike with 100mm Sid 32’s that has the standard tokens in and it’s crap compared to my 35’s now so I’ve ordered one for that as well….. I’ll leave another review when it arrives.

My Fox 32SC was the worst fork ever made.
Installing a Trutune made it into a great fork. The fork became plush with good holdup, progressive and compliant with good bottoming resistance.

I was sceptical, but this has completely fixed my harsh zebs. Previously I could never get full travel, and my forks always felt harsh and terrible. Now with the trutune thingo installed, my forks are plusher, have plenty of midstroke support and I'm getting at least an extra inch or so of travel. I'd highly recommend to anyone who feels like their fork is ramping up to hard. Best upgrade I've made in years.

Love the feel of my fork with the TruTune installed.

Worth every penny, love it!

Tru Tune Flow has made my Rock Shox fork much more plush & I now use most of the travel

Ride more preasure one click more low and high speed compression the feeling is softer and i can go faster

I bought this after listening to the downtime podcast, I was interested in taking out the trail chatter which it does, but the most impressive part is how it handles bigger drops!

I consistently use almost all of my travel now but still haven’t bottomed out my fork (lyrik). I only do drops up to about 4 feet though.

On the climbs I take the compression all the way off and the fork is insanely compliant over small to medium bumps and is a huge advantage on steep hard technical climbs.

Descending I crank the compression back about 2/3rds of the way up and it’s pure butter.

Works better than I ever imagined so I put one on my wife’s bike and she now is almost using all of her travel too (despite being an intermediate rider who doesn’t go that fast)

Awesome product, completely changes the feeling of the forks! Now running much higher pressure in my 38’s yet still feels way plusher through everything from techy downhill to big jump hits.

From reading the reviews & information, the Trutune cartridge sounds like a contradiction to physics - you put something that takes up more space into the fork and it has the effect of increasing the volume! I checked the compression ratio before & after fitting using a Shokwiz, & it does! It makes the fork noticeably plusher in the early travel, not quite coil like, but close. Impressed. Fitted one to my Pikes too.

Amazing, totally transforms the fork. Gives you so much more support and grip it's insane?! Super simple to fit and set up, cannot recommend enough!

Honestly I just like trying different things that are made to see if they perform as promised.
The addition of Tru Tune cartridge to my 180 Zeb Ultra is amazing. It was set up with no tokens and I use it on a Nomad as my DH bike. While the fork worked really well, I ran out of adjustment on lightening the rebound adjust. I don’t know how it worked but the Tru Tune installed with all the same adjustments before installation. The fork
Is so plush and reactive to the terrain compared to before. While it was good and I might add better than the Fox 38 Grip2, this made it that much better. Gonna get one for my Lyrick as well.

At first the only thing I noticed was the need for more air pressure to get the same ride height. However once I had that dialled in then I started to notice using full travel (was only reaching 90-95% with 0 tokens). The general ride characteristics is a subtle change, fork feels a bit smoother on small bumps. This is a tuning upgrade so it’s not like having a new fork it is like fine tuning an already functioning system.

As a lighter rider I’ve always struggled to get a plush feeling from any type of air sprung fork. Even running at low pressures with no tokens in. I gave in of these a go at Ard Rock and if seemed to really help it the forks feeling harsh the got into and beyond the mid stroke. Well today I managed to get out into my local trails for the first time and selected a few choice sections where my girls had always felt particularly harsh. I could be happier with how much better the feeling was. Non harsh clatter and felt support all the way through the travel.
