Hello folks,
I have to make a chainline that is as close to fully enclosed at possible for work, we are going to be making a handcrank generator where all kinds of fun things like hair and clothes are going to want to get caught up in the gears... I am having trouble finding one of these that we can purchase, I was wondering if y'all could help me.
I have found lots of bike that have fully enclosed drivetrains (eg.
http://en.wikipedia.org/wiki/Gear_case) but I'm having trouble finding them for sale independently of the bike, and for a 52+ chainring.
Any help is appreciated!
