My best estimate is 350g from the wheels, assuming a 1500g wheelset, and probably 100-150g assuming a 650g or so crankset. I do plan on selling my current wheels to make up for a little of the difference IF I go that route, also the crank for whatever it may bring if I go that way.

Any estimates on the value of the wheels? I was thinking something around $200 +- . I had also toyed with the idea of running tubeless on the SL23's to save another 200g from the tubes (but with a few grams from the sealant I realize). Can anyone comment on the state of tubeless road tires?

Keep the ideas flowing. I like the idea of the FSA SL-K cranks, but they don't really seem to save that much weight for the money. I also like the sram red if a deal could be found.

Thanks for all the replies.
