Circlips
Don't understand either why circlips are't used- the round wire section ones are particularly good as the chamfer on the ends of the gudgeon pin makes them seat even tighter.
Raced/built many high revving bikes,never had one pop out.
The mangles on the front of our planes can't really be classified as high revving at around 2700!
