    Front Fork/Hub Fitting
====Gabelausfallenden und Vorderradnaben====
The forks used on most Nottingham Raleighs have keyhole-shaped axle slots. These are designed to fit Raleigh hubs, with thin (5/16") solid axles and wheel retention shoulders on the cones. The spacing between the inner faces of the fork ends is less than the modern 100 mm standard. If you wish to mount a modern hub on a Nottingham Raleigh, be prepared to do some filing on the fork ends, to enlarge the lower part of the slots to fit the modern axle. Use a good sharp file, and, if possible, have the fork end itself clamped into a sturdy vise. If you don't, vibration of the fork will make it difficult to file. Make sure you file both sides the same amount, so the axle will not go in crooked.

The fork blades should be spread to match the over-locknut dimension of the hub. The dropouts will need to be realigned as well, to avoid bending the hub axle after the blades have been spread. The fork rake of Raleigh three-speeds is rather large, and so trail is less than optimal, and unbending the fork blades a bit can improve handling. I hesitate to advise realigning a fork unless you have access to a proper jig. You could just replace the fork instead.

    Rear Dropout/Hub Fitting


    Most Nottingham Raleigh rear dropouts have narrow (8 mm) slots intended for the flat-sided axles common on Sturmey-Archer and other older British hubs. This still works with modern Sturmey-Archer and SRAM internal-gear hubs which have flatted axles. Most other modern rear hubs are 10 mm, some are even 10.5 mm, so you will need to file the rear as well. Shimano internal-gear hub axles are flatted, but the anti-rotation washers place the flats at an angle to the dropout slots. We recommend doing all of the filing on the bottom of the slot. This eliminates the risk of making one side higher than the other.

    Dropout spacing on bikes made for 3-speed applications is typically 114 mm (4 1/2 inches). 5-speed derailer systems usually used 120 mm. Many upgrades will call for a wider dropout spacing.
