The BT-2 4th-Hand Brake Tool is a ratcheting wrench that allows you to pull cable and hold it in place as you make brake and derailleur cable tension adjustments.

- Familiarity: I've used it several times
Stretches the cable and locks into position so you can use both hands to make any other adjustments necessary and tightening up the pinch bolts.
An absolute necessity? No ... but a really nice tool to have on hand.
Great tool for anyone with multiple bikes trying to get the perfect tension on their cables.
This does actually help but certainly not a necessary tool.
