Hallo
Beim Stöbern auf der MTBR Singlespeed-Page ist mir folgende Möglichkeit zum Spannen der Kette aufgefallen:
"Ghost" or "Phantom" Chainring
Simple and effective. Do you have old chainrings laying around? It may take some experimentation, but you'll likely find a setup that works for you. Larger chainrings and/or moving the ghost chainring closer to the rear cog/freewheel will give you more tension. The main thing to watch for with this setup is chainstay clearance with the ghost chainring. Chainring bolt spacers (~2.5mm - 3mm) can be added up front to move the chainline inboard a little for additional clearance. The setup shown uses a 32T drive chainring, 32T ghost chainring, and 18T BMX cog.
NOTE: The ghost chainring does not need to be the same size as the drive chainring.
Another benefit to this system is that you should be able to run fixed gear with this setup, whereas you can't with spring-loaded chain tensioners.
Was zum Teufel ist das? Hat sowas schon mal einer von Euch ausprobiert, regelmässig fahren wird es wohl keiner, dafür ist es wohl doch zu, hm nunja, wenig elegant.
Aber ist mal was Anderes.
