I've written about Rinko in the past. "The basic idea is that if you put your bike in a "rinko-bukhuro" (a lightweight nylon bike bag) you can take it with you in the passenger compartment of a Japanese train. Since Japanese trains are fast, punctual, and plentiful, this seems a fantastic way to tour various areas of the country in one visit."
To facilitate Rinko, Honjo makes fenders that have removable sections. We ordered a sample set of 50mm hammered Honjo fenders early last year. They finally arrived. We had planned on stocking them, but ever increasing Honjo prices mean that they would now sell for over $250. That's a lot for a pair of fenders and I doubt we could sell enough to justify importing them. Still, I thought you'd like to see a couple of photos.
This set is designed for a bike with a front rack. The front fender is one piece and, presumably, will be attached in the normal manner and to the front rack. The rear fender has a quick release that allows the back section to be removed. Thus, when the fender section and both wheels are removed, the bike fits into a fairly compact Rinko bag (or into a Japanese closet.)
In addition to the joint in the fender, the Rinko fenders have special hardware with wing nuts at the dropout eyelets, so the stays can be easily removed without tools.
Before you ask, Perry already bought this set for his upcoming Banjo Camper frame. And, no, they cannot be special ordered unless you want 50 sets. Sorry.
