Owen,
ya need ta get them on the 80a's as the 77's are a bit slow, also they are going to have issues turning those big gobs of urethane on a 195mm wide hanger. I have been running a set on 186's with the softest Venom barrel/cone combo and it still doesn't want to corner, I'm going to try 170's next.
Cheers
Ado

Actually Adrian they are fine, the width of the hanger actually make it easier to turn as your moments of force are further from the pivot point. An easy way to look at it is the longer the lever the less force is required to make it pivot.
At the moment these guys are just starting out they ride rough canberra roads so having a softer wheel with loads of grip is a magical thing.

Forget what i said.... haha
Just read this
http://www.randal.com/guides_faq.htmlGood to see more luge crew riding in canberra!

sorry mate, I stand corrected, sad that after all these years I should be so ignorant. Enjoy the rides and watch for dips in the road.
Off to learn how to suck eggs again

Ado I wasn't having a go at you and you Know a lot of stuff about luge and downhill but I'm afraid that your argument goes against physics.
Think of the board and the hanger as the two handles of a pair of bolt cutters the further along from the pivot you hold the more power you seem to have this is due to you moment of force being further from the fulcrum. You body and the earth are your hands and the gravity pulling you toward each other is the muscle. The amount of gravity can't change very much but the amount torque it can put through you bushings can be increased.

Owen,
your theory is correct it is just the positions that aren't.
The pan/your body is the lever, the pivot/kingpin is the fulcrum and the wheels are the thing you are moving. The greater the pan width to hanger width ratio the greater the force on the wheels resulting in easier turning. The lower this ratio the more stable the setup as the slight movements of the body don't have as much effect. It is why you don't see slalom riders running wide trucks.
Cheers

I was waiting for a slalom truck rebuttal when I read this earlier. You gain stability but lose responsiveness with wider hangers

hey is anyone heading over to the creature demo at belco this arvo?
