Chain falling off? This might help...


Gaerlan Custom Cycles have a web page showing a neat roller which stops chains falling off single chainrings.



The full story is at:

and has reportedly stopped all chain derailments since being fitted.

Strikes me the mounting could be cobbled together from old light brackets or something if no strip alu is to hand. You'd have to be sure to make it stiff enough, though, else the chain could sneak out...

Thanks to the Trikes mailing list where I spotted this...

  • Seems to me that those thin plastic disks, slightly larger than the chainring, fitted either side of it, woiuld be lighter do the same job
