Abstract
Chain guides for the front sprockets of bicycles are disclosed. More particularly, the chain guides are adapted or configured for bicycles that have multiple (usually 2 or 3) sprockets/chain rings mounted to the crank assembly. The setup is provided to freely allow shifting between the gears. All of the chain guide variations presented are provided with an outer flange attached to a roller section so that these portions roll together with the chain they restrain. Additional optional features include aspects to do with roller positioning, bracket mounting, roller configuration and supplemental chain restrain means (including a stop/post member and inner roller flange.)
