Building a Kotori into the ultimate trail machine? You'll probably need one of these.  This CNC'd beauty replaces the drive side dropout and throws a derailleur hanger into the mix!

The Kotori's sliding dropout design means that the frame can be run as a singlespeed or you can replace the driveside dropout with this bad boy and run a derailleur. The stock hub takes a cassette and the frame already has all the necessary cable attachment points for a derailleur cable, so there is nothing to stop you from making your Kotori shifty!
