Re: Live vs. Dead axles

Live, live, live. Dead is not simpler when chains are involved. 217 has used both. In 2000, 2001, and 2004 we used dead. In 2002, 2003, 2005, and 2006 we used live. After 2002 or 2003 I would have said dead, because we poorly implemented the live axles. In 2005, we saw the light and live is the way to go for us. The main advantage: you do not have to touch the chain to change wheels because the sprocket is not attached to the wheel.

We use hex shaft (3/4" this year, but maybe smaller next year) with a hex hole in the wheel and sprockets. Wheels are off in no time flat and the chain doesn't get touched.
