8mm axles

[Gustav]

No that's wrong,a hollow tube is alot stronger than a solid cylinder of the same weight that's all,boring out a cylider doesn't make it stronger.

The UE axles eliminate the drive pin weakspot which according to them make their axle 10x stronger than a solid axle with the weakspot.Hollow buggy axles use a drive pin (the ones i've seen anyway).I'd bet my house on the fact that those 8mm UE axles are many times stronger than a hollow buggy 8mm axle.
