Fixed Super Light Super Safe

Im still trying to work out what wheels this build needs.

Im quickly coming to the realisation that this is where its going to make the biggest difference and also its the most difficult.

I was actually thinking around the front MTB front hub on the rear in relation to the 40:60 with the weight limits. As its a MTB hub, its actually designed for serious punishment including going fast, downhill into things. This means that the forces applied to it are going to be much much greater than me using it as a road hub.

dammit says that he is interested to see if it can be done with the lefty hub. Is there a way to get a custom light axle easily? Who would be able to make it? Has it been done before by anyone on here?

Its worth remembering that there is a XC crowd with a lorry load of weight weenie £s in their pockets. So there are plenty of front hubs that wont cut it as a rear fixed hub. Hence my warning regarding weight distribution, and its effect on minimum rider calcs when using a front on the rear.

The lefty axle would be simple enough to machine. I've no idea where you'd have this done though.

It would need to be somthing like this....

Which is a dummy axle for wheel building. You'd of course need it to have threading for locknuts and track nuts.

This is a homemade dummy axle, which shows the difference in the ID of the bearings.
