The Optima Baron has a unique chainline that requires a unique idler system. Thus, the Optima Baron Power and Return Idler Kit. Featuring two Return and one Power idler, all of which are allowed to float, this kit has just the right combination of idlers, chaintubes and hardware to get the most efficiency and to keep the chain off of your bike's tire and fork to give you the greatest steering maneuverability available.
The heart of the kit is our cogged power idler to transfer more of your pedalling power to the rear wheel. The power chain is further controlled by a length of the stock chaintube that is held in a custom self adjusting bracket that allows the chaintube to move as you change gears. This custom bracket, which replaces the stock mount in front of the seat also holds a floating return idler. The second return idler above the fork has an additional bracket to keep the larger diameter idler clear of your fork.
