Tuggnut
The tuggnut is the perfect wheel retention device for all horizontal dropouts (and by that we don't mean sleeping tramps). Forged by large machines from stainless steel, it's sturdy, beautiful and with the provided adapter will also work with quick release axles. After the ride (or during. Hell, even before), it doubles as a bottle opener, so no more glass shards in your favourite beverage. 29.99 - remember, you only need one...
