Axle Material

Are titanium axles legal? Do different associations/classes have different rules pertaining to this? I typically run a 4 stroke but just curious in general.

Not sure about USA, in Australia the answer is No it would not be allowed (point F in the first picture).

Indeed you’ll have to check with the rule set governing the races you run. Typically only ferrous materials are permitted. So titanium, aluminum and carbon are out.

No URANIUM??? :joy:

I don’t see Plutonium or Tritium listed on there though!!!

@Bimodal_Rocket this has immense meme potential.

I’m so bad at wrenching stuff tho!

Uranium would be a lot safer for ballast than lead. It’s a lot harder so you won’t get flakes and contamination of seats.

Ti is notch sensitive, which is a slight problem if you’ve got a key under the brake rotor preventing impact loads from spinning it round.

I’ve read that bismuth is an alternative to lead. I prefer to use 24karat gold, personally.
