How important is smoothness in fixie play anyway? It’s not like you’re trying to throw as hard as possible to get as much spin time as possible. Vibe (or lack thereof) just isn’t really a factor, is it?
If you want to do string tricks on a fixie, then smoothness does kinda matter. Vibe can really kill the spintime of a fixie. But only in this instance.
I kinda got the impression that doing 1A tricks on a wood fixie was akin to doing 2A tricks on a competition bi-metal. Possible, but not what its really designed for. Am I wrong about that?
The pros of metal inserts and and axle i that it will not fly apart on you in play. Both the axle and the wooden sleeve are replaceable if you need to. You can also adjust the gap with different length wooden sleeves. The con of this is that if you tighten it too much you can crush the wooden sleeve.
The wood thread axle advantage is that there is not the extra weight that the metal parts can bring. There is no another advantage as far as I know.
I think a Survivalist with metal inserts and wood sleeve would be the thing! Or even just screw apart with the aluminum axle. It plays really nice with the aluminum.
