Really appreciate the thoughtful design of this tool. Storage for different adapters, metal ring click to fit so that everything stays in place, locking stops that hold the chain at its lifted position and then quick release. Perfect tool for cleaning, maintenance, or anytime removing the rear wheel need to come off - think mounting on a trainer with a free wheel. Lock this on when mounting or removing. keep the chain out of the way and makes the whole operations quick and clean. Highly recommended!
