Step 6Mount the mudguard on the brake bridge.
iImage Information

Unscrew the bolt and mount onto your rear brake bridge. If the mudguard sits well and doesn't touch the wheel, well done. If it is touching the wheel you may want to add structural support and lift by using the spare spoke and nipple. You can thread the spoke through one of the holes and attach to the seat post or frame. I wrapped mine around the seatpost bolt, which works fine for now.
The beauty of this hack is that it is easy to fit and remove, is worthless to thieves and is recycling busted wheels. Any improvements suggestions on materials and design are welcome.
