Ryder Nutcracker Presta Valve and Disc Tool

From Ryder:

The Nutcracker mini tool is designed to get you out of sticky situations when dealing with tubeless valve removal/installation.

Patented design for removing tubeless valve rim nuts of varying sizes, the PV/FV Core remover tool, with storage for a spare removable core (included).

There's also a reinforced disc brake pad-spreader - perfect for retracting pads if you've accidentally removed your wheel and pulled the brake lever.
