Homemade Tensioner



I made this chain tensioner awhile back. It worked great on smooth roads but not so hot on rough trails (maybe it needed a design tweak?) The reason I just didnt shorten the chain was I liked to switch cogs based on race terrain and conditions.

Took some flat aluminum, drilled some holes as shown below. Then stole a derailleurs wheel and screwed that onto the plate. The trick is to bend the plate the right amount.

nice. any chance you can modify it so it pushes the chain up? you get better wrap that way.
