Made by Cycle House Shibuya Rear carrier for Brompton (purchased around 2012) Aluminum CNC machined, clear coated While it's lost some of its new shine, I think it's still usable, so I'm putting it up for sale. It rolls incredibly well. I think the wheels are probably from inline skates or a kick scooter. Always take measures to prevent runaway when transporting by train. Hold it by hand, or secure it with a rope or belt. It may run away on its own. It will roll even on slight slopes, such as on a train platform. A spacer has been inserted on the right front wheel (as viewed from above), extending it slightly outward. This was done to prevent it from tilting to the right when folded (purely for my own satisfaction). If you want to return it to normal, please use the included bolts. ※ See images 10 and 12 The stay that is bolted together with the rear brake caliper originally had round holes, but I cut them to allow installation without completely removing the brake caliper. ※ See images 5 and 6 The top plate and the rear stay mounting section are threaded. After positioning, tighten the cap bolts and then tighten the lock nuts. ※ See image 11 Some ingenuity and tricks may be required for installation. There are some minor scratches, but please refrain from purchasing if you are concerned about them.
