No more jumping chain! The Flip Guide is Reverse latest solution, which allows you to adjust lightning-fast settings. For easy cleaning of the chain or removing the crank, you can fold the top guide by hand into the service position. After the work is done, simply return the guide back to the raiding position until it locks into place. So your chain runs safely on the roughest tracks. For further adjustment, the Flip Guide has a sophisticated micro adjustment system. The guide can be adjusted very finely with a hexagonal screw so that it lies perfectly on the chain line. Very simple: tighten or loosen the screw to position the guide in the middle of the chain.
