Extralite Ultrahub v2.0 rear hub bearing preload

[Anth73]

Hi All,

The micro tuner on my Extralite Ultrahub v2.0 rear hub loosens by about a quarter turn each ride (50km - 100km). This results in some side to side play in the rear wheel and brake rub. I manually tighten the micro tuner after each ride. Do other users of this rear hub experience this and know what may be the cause and how to stop it happening?

Thanks

maybe a new microtuner will fix it ?

Mine does the same on my CyberRear spd. Might try some different thread lock to see if that can hold it.
