topeak micro rocket AL or CB
 

Hi all, first time poster, just got into biking and loving it.

So the Topeak micro rocket carbon is like $40 retail and I saw online the aluminum version for less than half the price. so my question is, would it be accurate to say the two are exactly the same thing, and that the ONLY difference is the exterior (carbon) material which save you 10g?

Yes that's correct.
