Ostrich SL-100 ULTRA Rinko Bag

The lightest Rinko bag in the world! When not in use, it’s smaller the size of a couple of energy bars and fits under your saddle, in your handlebar bag or in a bottle cage. Large enough to fit a full-size randonneur Rinko bike, the bag is made from ultralight material and weighs just 150 grams. The superlight bag is intended for experienced riders, since it is more fragile than the sturdier, but otherwise similar Ostrich L-100 Rinko bag.

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.

The bag comes with a carrying strap that attaches to the bike. (The bag only drapes over the bike and does not bear the weight of the bike). Three small straps keep the parts of the bike (frame; fork/front wheel; rear wheel/rear fender) together and rattle-free.

Pro Tip: The ultra-thin material of the SL-100 ULTRA bag makes it a bit harder to pack the bike, compared to the SL-100 and L-100 Rinko bags.
