I would have given a 5 star if it wasn’t for the strife when adjusting it to my Specialized Fat Boy the shift cable routing seem to be in the way no matter how many times I changed the arbors and move the frame support . after watching the You Tube video ( which every one should ) did some tinkering , went live, PERFECT!. The Fat Boy is particularly difficulty when removing and re-installing the rear wheel , plus this tool has somewhat of a learning curve. this tool is a Godsend. A great addition to my arsenal of bicycle tools.
