Rotafixa

This ingenious technique – a trick pulled straight from the magic hat of track legend Giovanni Pettenella enables the secure assembly of a track sprocket without having to use the traditional lock ring too. This is very handy as it enables you to use hubs that don’t have space for the lockring, and inverting the rotational directions shown it is possible to remove the sprocket without having to use special tools.

I have used this method many times and it seriously does remove the need for a chain whip, you will however need a lockring tool, unless…
1: Like me you are happy to use the hammer and flathead screwdriver technique or
2: You dont use a lockring
