I hope you enjoy your day.
A few days after of using my bike I have some troubling feeling about it. I can hear a cracking sound or something similar, and on the internet I found out the cause.
I concluded and was hoping that the problem is only the seatpost.
But I've found another one. When I pedal, the bike also create a cracking sound, especially when pedalling too hard. I hope that with a little bit of cleaning and lubrication I would be able to fix that.
But sadly again, sometimes I also hear the sound when I brake too hard.
I hope it's gone. For now, my seatpost is slipping when I seat on it.
My questions is: since my bike frame is made of an aluminium, what kind of grease should I use?
In the shop that I visited only "Ceramic" or "Teflon" were available. Which one is most suitable? Please remember that my frame is aluminium and the seatpost is steel.
Which grease is suitable for two different materials, in my case aluminium and steel?
I found those on the internet and they are available in my local bike shop:
Little hard to find:
Which priorities should I take into consideration given the choices above?
