  1. Standard croll. No problems

    Posted by Ryan on 2nd May 2018

    Solid device for frog ascending.

  2. Best Croll I've used

    My 3rd ascender after many years of SRT caving. Love this new style--small, sturdy, light. I just put 110 feet of ascending thru this Croll and it performed like a champ!

    Old style was better, but this one works fine
