Aluminum axle/carbon fier

[cannondalemaine]

Well I have been finding parts to make my quad much lighter and one of the things tops on my list is a aluminum or carbon fiber axle. I figured that would be good for a bunch more pounds of rotating mass to get me moving quicker. I have found some for 450r's and 250r's but haven't found anything for a c-dale. So my question was I heard that RPM's fit as long as it has the 250r hubs I believe. Was just wondering if any 250r/450r axle will work as loing as I get the hubs for it? Would anybody know this to be true? My 450r axle looks like it would fit but I don't feel like taking both axle out just to test fit if somebody already know. Also anybody try one before? Sorry for all the questions lately?

Contact Peterock or Speed1b both will know exactly what is needed for a conversion. I believe it can be done since I did it with a 250r axle but there were some custom spacers needed.
