Are crank bolts one size fits all? I have Truvativ Holzfeller cranks
Nope. As far as I know the diameter of the bolt is the same but they are available in different lengths to accomodate different set ups. Eg- short bolts for single chainrings and longer ones for double or single ring and bash guard set ups.
are their any zero gravity rooms or places to go in australia let alone the world that you can just pay and go into ??
Yes. It's called a pool. Seriously this is how Nasa does most of their training. Only other way to experience zero G is to head over to Russia and give them some money to take you up in the plane that the cosmonauts train in. It's programmed to rise and fall in a specific pattern to simulate zero gravity and it's the only real way to get a zero G effect without actually going into space.
Alternatively Bransons space plane shouldn't be too far away, 2025 I think.
The original Zero G plane (that still operates) I believe was actually American. You can YouTube it I'm sure, there's bound to be ad's on there. Doesn't matter either way, but there's more than one operating.
Is it true that cannibal's don't eat clowns because they taste funny?

Why does the RTA in NSW errect signs that say "Keep Left Unless over taking. Penalties apply" on motorways when it should say "Keep left Unless over taking everywhere, all the time, unless you really need to be in that lane, you tard!."??
Would the fact that the world has ever increasing desert(s) have more impact on sea level than a pissy little temperature change?
I don't know, but why do you think that it would/might?
1) Where does McDonald's Soft Serve hail from?
2) Are we limiting the amount of dimensions we (humans) can "see" due to our dependency on light?
