I was fortunate enough to meet the Trutune team at an event in Ballater, Scotland where they had a demo rig available to show the insert in action. After purchasing and installation i have to admit that the insert has made the fork feel more progressive and i am now using the full travel of the fork without ever bottoming it out. Also worth noting that the insert has improved the microvibrations i used to get going over loose and rocky ground at speed. So far, very impressed.

I Have a Fox 36 Performance Elite (Grip2 damper) with a short 140 mm of travel on my Norco Optic, I bought the Truetune because I found the fork very arch despite all the set up i've been trying. Maybe be this fork is very good in the 150/160 travel ? Anyway, I'm very happy with the Truetune, the fork is very cofortable now ! A big difference in fact ! I live and ride in the south east of France on very rocky trails, in this conditions I can tell if the suspensions are good or not. I used four spacers (like recomanded in the Norco app), now, no more spacers, just the Trutune. You must increase the air pressure and speed up the rebound of the fork, I added a click or two of compression, and i feel a real big difference now ! I'm very happy of my purchase ! I think it's a must have on short travel forks. I can't tell on longer travel...

I thought a lot about how I could improve my Zeb fork. It works well and is smooth, but I was only using a bit over 140mm of its 170mm of travel on my local trails. I am not riding Red Bull Rampage, but I am not pottering around a cross country course either.

After fitting the Truetune cartridge and raising the pressure by 5% I am now using 160mm of travel on a trail that is not particularly challenging. I know a 4 foot huck to flat will probably bottom it out, but I will deal with that if and when I do that.

As well as having the extra travel, the fork does seem to react quicker to square edge bumps. hitting rock gardens at speed is not an issue. I feel the fork gives me more front end grip. Now, Truetune, when are you going to release that cartridge for the RS Super Deluxe that you have been working on? I notice the lack of traction in the rear suspension more, now that I have the Truetune cartridge in the fork.

Looking at the cartridge, this wasn’t a cheap upgrade for what it is, but it is very good value for what it does. Big single crown forks should come with these from the factory.

Bought to improve the feel of the fork. Now gets full travel is more supple and sits higher in its travel. Was dubious but it has transformed a great fork into a better version of its self.

This revolutionary product completely redefined the characteristics of my fork making them feel far more responsive and the whole bike more planted

From the original packaging to the trutune insert itself; everything is high quality.
I increased my pressure roughy 9psi from 101 to 110psi. The fork rides plusher with great mid stroke support. On super steeps I dial up the compression to keep it riding a bit higher. Overall I’m very impressed in the insert.

Not sure I understand the physics so I’m putting it down to witchcraft. I added 10psi and finally got full travel from my forks, how does that work?!

I'm running a zeb select 170 on an ebike. I found it supportive but harsh on small bump sensitivity. I'd just come home from The Alps and decided upon giving trutune a try. It made an immediate difference. I have since ridden in Wales 4 days solid riding riding red and black trails. I throughly recommend this product. I don't do big jumps and I haven't actually used the full 170mm of travel but most of it on rocky descents.

Took a few run to find tune rebound and compression and get the right pressure but now I have it dialled in it’s amazing.

Works as advertised and reviewed by bike mag tests. Exactly the solution I was looking for as a 62kg rider,not racer,with a 180mm Fox38!
No fatigueing ramp up toward the last part of travel.With the stock fork,even with zero tokens fitted,if I tried dropping psi to stop the ramp up,it rode a bit low around sag to mid travel.I left it at that as I don't like sudden ramp up.
Now with theTruTune fitted,I get full ride height AND use full travel without the dreaded ramp up! I added 10% more psi and backed off the compression a bit.

I had never heard of this product until a friend recommended them. We were lucky to demo them at ard rock. It made the forks a lot smoother through all the travel.

I was pretty sceptical when it turned up in the post that this little black tube could do anything but as soon as I put it in my new Lyrics I could feel a difference
Very impressed

I have been unhappy with the performance of my fork since I bought the bike. I run into a wall of progression at ~75% travel. Reducing air pressure would drop the fork riding lower in its travel and steepen my HTA (A worse problem for my intended purpose). I bought Trutune as a last ditch effort before buying a Lyrik or Fox 36. Install was very simple, it has made the fork more linear as desired. I am still working on perfecting my setup and may not get there but a definite improvement for what I was looking for.

Had low expectations, sounded too good to be true but it did everything I wanted it to. I now use more of my travel, the progression feels more linear and small bump sensitivity is much improved. Feels like the front wheel tracks the ground better through the ruff stuff.

Gave this a try after reading a couple of reviews. Have always hade trouble getting the use of all of my fox 36 performance forks travel. Having to drop the pressures way down to get close. That in turn really unbalanced my bike. Plopped the trutune in, and could easily bump the pressures back up and now get full travel when I need it!
