If I were interested in the MAG 90, I wouldn´t buy it before Tune release a carbon axle-version. The axle is 17mm Aluminium (MAG 130 has 15mm Carbon)...with that diameter but made of carbon would be much stiffer that current offerings

Tune always release a new superlight hub every year....Eurobike ´10?? MAG 75?

Tune already has the 130g Prince Dezibel disc hub with the magnetic cassette body mechanism. It's said to be quite loud but saves weight. It's supposedly more sturdy than the pawls system Tune uses throughout most their current range. I for one would like a Mag90 with carbon axle and ceramic hybrid bearings! :D (no fool, erm... full ceramics for me, thanks)

Tune Dezibel is a proto yet from what I have read...and I think that it is a carbon axle version of the Tune Prince HighFly (the current lightest disc hub from Tune--150gr)

No MAG90 anytime soon, as I just read on the Tune website.

Was mit MAG90 und Dezibel los ist?


Nun,, ich habe als ehemals passionierter Motorradfahrer schon in meiner Jugend Null Toleranz gegenüber ausgebohrten Auspufftöpfen gehabt. Und heute fehlt
mir ebenso das Verständnis, wenn Maschinengewehr-ähnliches Geknatter durch...den Wald tönt. Eben so hören sich unsere Stirnverzahnungen an. OK, letztens
haben wir das in den Griff bekommen. Stattdessen wurde ein leichtes Knarzen
hörbar, vorher durch infernalisches Feuerwerk verdeckt. Im Mitnehmerteil der
Stirnverzahnung bildeten sich unschöne Abdrücke, obwohl die Druckbelastungs-
grenze bei weitem nicht ausgereizt war. Nachdem mir gute Ideen nur im Zustand
der Entspannung kommen, also im Bett, beim Sport oder auf dem Klo (bestimmt
nicht bei der Arbeit), nahm ich letzte Woche meine Altersfreizeit und siehe da:
Könnten die Druckmarken in Wahrheit Reibmarken sind? Man muß dazu wissen, dass die Wandstärke der 17mm- Achsen von MAG90 und Dezibel verdammt
gering ist. Neue Lektion: Die Steifigkeit geht bei der Wandstärke nur linear ein,
es braucht also viel Material um die Steifigkeit zu erhöhen. Aus der MAG 90 würde eine MAG100 werden. Sch...!

Nicht vielen gelingt es aus Sch... Gold zu machen. Also nochmal abhängen und
wieder abhängen bei Musik von Dire Straits, Eric Clapton, Pink Floyd, bin halt
Baujahr ´53 - und reichlich Dezibel, dann erwacht der Alchimist in mir. Das Gold ist
zwar schwarz - jetzt ist die Katze aus dem Sack - aber das kennen wir vom Erdöl
auch.


Vielleicht sehen wir uns auf der Eurobike, bis dahin muss ich das Geschmeide
noch formen.

Gute Gedanken, gute Dinge und gute Laune

Euer Uli Fahl

Dunno how good anyone's German is (Germans, anyone?), but I understand that Uli Fahl, owner of Tune, writes about lack of stiffness in MAG90 and Dezibel axles resulting in squeaking, and also that he cannot reconcile himself with releasing a MAG100 with stronger axle by increasing wall thickness.
