They are heavier though and oddly enough there is a graphite part so im going to go with the graphite. It is much lighter.
I would have used my racer2 hubs but they were just slightly smaller.
You are talking 2 grams difference between the carbon ones and the alloy ones. The alloy ones clamp to the axle so the wheel does not pull them off and you wont lose the cross pin. Also the alloy ones are precision machined so they run perfect, unlike the plastic ones which develop play after enough crashes. Lastly you can over tighten the plastic ones and crush them against the outer bearings. I have done that on my original R40.
