Sturmey Archer hub problem
My commuter bike has a Sturmey Archer 5 Speed alloy hub (X-FR5) which has now started to slip out of gear regularly in gears 4 & 5. When this happens, it slips for a small part of a chainwheel revolution before taking up the drive again. If I backpedal when this happens, there is a clicking sound like a pawl in a freewheel but slower and much louder.
The lower gears 1, 2 & 3 work fine.
The adjustment of the gear shifting chain and pull rod is correct.
The operating cable is well lubricated, and as smooth in operation as it always has been.
I have also tried deliberately overadjusting it in both directions without improvement.
There are many websites with Sturmey Archer info but the X-FR5 hub is not covered in detail.
Lastly, how do you oil a SA hub which has no oil hole in it?
