Luft Fusion Tuning-Luftkammer

[Leemi]

Alter

schonmal dran gedacht dass eine Fehlersuche etwas Zeit in Anspruch nehmen kann?
und dass der Herr vielleicht nicht 24/7 Zeit hat hier im IBC rumzulungern...

Du hast doch da was vorgeschlagen:


einfach mal ausprobieren schadet nicht

Entschuldige bitte, falls Du Dich angesprochen fühlst. Eigentlich hatte ich auch Dich gar nicht gefragt.
Das Produkt kommt ja nicht von mir (oder von Dir?!?). Es gibt keine Zeichnungen über die Beschaffenheit, noch sonst was.
Es obliegt deshalb ausschließlich dem Erzeuger, das Problem in die Hand zu nehmen.
Relax. ALTER.

Mir hat er auf Direkt-Nachrichten bisher immer innerhalb einiger Stunden geantwortet. Selbst wenn ich den armen am Wochenende belästigt habe. Immer hilfsbereit und für alles wurde eine Lösung gefunden. Also keine Angst

Der Service (eines 1-Mann-Unternehmens!) war bisher immer exzellent! Ich hatte in Finale Probleme mit der ersten Version der LF und mir wurde angeboten eine neue dahin zu schicken und die Kosten für den Einbau zu übernehmen.
(Habe ich nicht gemacht, da Urlaub eh fast rum war.)

The second seal in the original air shaft is an oil wiper to prevent oil from the lower leg to get in the air chamber. It does not help sealing air. During tests I found it's unnecessary, and the larger shaft already has more seal friction than the original, so I don't use it. Fox is doing the same with their 2026 "glidecore" models to decrease friction.

Seal kits are available for all models, just get in touch.

I's a delicate balance between reliable sealing and low friction, and it's something I'm constantly trying to improve. I hope this will lead to backwards compatible fixes.

@RGTec Luftshaft is just fine in general, but: It always releases some negatitve air into the the lower legs (identified by the pressure release buttons at arround 1000 to 4000 highmeters (or downhill)).
Any Idea? The NEW Lyrik lost some pressure from 110 to 100 psi. At this time, the equliazation between neg and pos Air seems just fine (the travel hight seems just fine, but after a while it feels like the fork is going harsh at this stage, until I presse the release buttons and pump up the "lost air".).
Thanks, else a very good Product!

das drückt in etwa aus was ich manchmal fühle. leider hat meine 21er Fox36 keine pressure release :-(
aber danke fürs teilen, dann beobachte ich das mal

ja, das kann ich auch berichten. Service ist 1a

Ich hab gestern meine 38 PE mit LF und Optimierung der Dämpfung und Buchsen von Riccardo eingebaut. Ich komme von ner Mezzer mit komplettem Tuning (die zuletzt vielleicht einen Service hätte gebrauchen können).
Die 38er lässt mich nach der ersten Testfahrt etwas sprachlos zurück. Ich bin noch keine so dermaßen geile Gabel gefahren. Die funktioniert einfach!

Hi, is LF suitable to heavy riders? I am 100kg.
I ride 22 Fox 38 grip2, fork is like jackhammer on small bumps.
Can LF make small bumps sensitivity better in high working pressure close to 130-140psi?

 

[SovietElmo]

The Luft Fusion will require even more pressure, about 30% more as a rule of thumb. I can't imagine the fork being supple with air pressures about 170 psi. You might want to consider a coil conversion, just my 2 cents though.

 

[GeorgiL]

Now pressure in my fork is 110psi, and 2 tokens,
so if i install LF my idea is to increase pressure to 130-140max.
I am a trail rider no big jumps, no bottom outs, my fork is 170mm travel, i never use more than a 120-130mm of it.
I buy 38 just for stronger chassi because i am heavy.

 

[Moehrenprincess]

Maybe you want to consider a lower pressure, if you only use that little of the travel? Could help with the harsh feel.

 

[GeorgiL]

Maybe you want to consider a lower pressure, if you only use that little of the travel? Could help with the harsh 80 to120 psi

i try everything between 80 to 120 psi, and every posible combination of compression, reboundand tokens best for me is 110psi.
Fork soon will be revalved to e-tune shimstack, next option may be Secus or LF, i personaly like LF because make negative and positive cambers bigger, Secus make only negative.

This setup doesn't make sense

 

[GeorgiL]

Explain please?

 

[SovietElmo]

Instead of trying every airspring mod you are much more likely to benefit from a compression unit that can actually provide compression damping.

Given your weight and given you are also looking for small bump compliance, it's unlikely you'd get that from an airspring that fits the Fox 38.

 

[DatJibbedNicht]

Explain please?

Why 2 tokens if you only use 130mm of travel?

 

[GeorgiL]

I ride it with 1 and no tokens, absolute crap.

 

[DatJibbedNicht]

Either there is something wrong with your fork or you don't need an 170mm fox 38 at all for the stuff you ride
You should contact Ricardo (rgtec.bike) He also offers tuning for the fox 38

Yes the Luftfusion does make the beginning stroke more supple by linearizing the initial hump in the spring curve.
But according to your description, it seems likely that something is generally wrong with your fork.
Prior to installing tuning parts of any kind, you should make sure that the chassis of the fork is in good working order:

• are the bushings good? (take out all inner parts and check if the stanchions glide into the lowers with no significant friction)
• are the stanchions and lowers aligned parallel? (does the hub glide into the fork without niggling/ do you have to spread the fork dropouts/ are the dropouts pulled together when tightening the axle?)

If something is off with the hardware, no damper or spring tuning will help.

Thought the same...

Thanks, that i want to know for LF.
Fork is brand new, ridden only 20-30 hours, but soon will be completely serviced.
Saddly i rode other fox 38 forks and they are same harsh crap when pressure exeed 110psi.
Forums are full of complains of heavy riders with same problem, so i want to know will LF make ride little bit better.

The GRIP2 has little compression damping (and of bad quality because in my opinion bad design decisions...) this requires additional air pressure to compensate. So any imperfection in the air spring curve is also amplified.

The fox "ebike tune" is actually softer...

I can offer tuning of the GRIP2 + bushing check/resizing + Luft Fusion installation.

Klingt für mich nach einem service der Luftkammer, zu viel Fett. War zumindest bei meiner 36 so. LF habe ich trotzdem verbaut, da ich mit 75kg fahrfertig eher sehr leicht bin. Beides in Kombination erbrachte eine für mich taugliche Gabel.
