Nobblies & Chain oiler
 

I recently fitted a rear Karoo in place of the Sirac and soon had the feed for my Loobman oiler worn through by the outside nobbles of the almost new tyre. If anyone is changing from intermediates (Sirac,Tourance) to nobblies and has a chain oiler (Loobman, Scotoiler) check the clearance and re-route as necessary. :BangHead:
