Tortec P-Clips Bracket For Mudguards and Racks
These handy little brackets allow you to fit racks or mudguards to bike frames without threaded eyelets or bosses.
Supplied in pairs with stainless steel nuts and bolts.
Measure the diameter of the tube you are fitting these to, and then simply select the nearest size, going bigger if required. You can use electric tape to build the frame up if need be.
