Selling a Abus Nutfix 100mm front wheel lock for standard 100mm spacing front quick release wheels. It replaces your quick release so that your front bike wheel can't be stolen. You have to lay the bike on its side with the lock facing up to be able to reveal the bolt which allows you to unscrew the front wheel with a 8mm wrench. The bolt can't be accessed when the bike is upright, so you can lock your bike with a lock around the seat tube and rear wheel without worrying about the front wheel being stolen since the bike can't be tilted on its side when locked to something.
Bought but never used. Asking $20
