Rene Herse Rinko Nut
With a Hirose-style split rear fender, a Rinko nut is used on the tongue that connects the fender, so that the two halves can be secured by an M5 bolt.
Rinko is the Japanese system of packing bikes for train travel. It’s an elegant way of converting your bike into a small package that you sling over your shoulder and carry on trains, subways, buses or in other crowded places. It is very satisfying to ride up to a train station, and 15 minutes later, your bike is reduced to a neat, small package. It’s also a great way to carry your bike in a car – it requires little space, and the Rinko bag keep your other luggage from getting soiled by the chain and other oily parts. A Rinko bike doesn’t need couplers or other parts that add cost and complexity, and compromise the ride quality. Consider a few small details when designing the frame, use a few special parts, and a standard bike can be packed Rinko-style.
