R e c o r d y o u r S e t t i n g s Use the charts below to record your BoXXer™ fork settings to return your fork to its pre-service settings. Record your service date to track service intervals.
F o r k R e m o v a l We recommend the following steps to remove your BoXXer™ fork from the bicycle. Removing the fork from the bicycle provides easy access to internal components and is more convenient than working around a complete bicycle. To assist you with post-service assembly, record the distance from the top of the upper tube to the top of the lower crown.
