My experience with fixed gear bikes and rear axle position/tightening is that when used on a track the challenges that fixies have, when used on open roads, are largely non existent. Axle slippage isn't an issue as skidding doesn't happen very often, if at all, on the track. Mere forward pedaling forces rarely are enough to budge a well secured axle.


I'll also add (and I'll not direct this at the OP) that many road fixies run the chain WAY too tight. Too tight a chain, besides wearing hub nd BB bearings at a fast clip, can produce very high forces on the axle securement (as well as ring bolts). Andy
