What size fork should I use on the Juliana?

100-120mm will work great, depending on what you want the bike to do. 100mm forks will give the bike fairly quick handling, with a more xc feel. 120mm forks will make the bike more stable at speed and are better for slightly more aggressive riders. We don't recommend forks over 120mm travel.
