That looks like the last of the Vendetta V.2, right before it became the V20 with the red frame and revised front end. My first Cruzbike was a yellow V.2, and like the one you have, I also swapped out the big yellow boom and polished aluminum slider for the updated V20 boom and slider, and chainstay. As much as I liked the look of the V.2 boom and slider, the revised V20 front end offered much more adjustability, and it got rid of an annoying creak that I could not make go away. I am a shorter rider, and as you can see in the first picture, I had to trim quite a bit of the yellow boom to accommodate my shorter legs (you can tell by how much of the Cruzbike decal is missing). The newer setup didn't require that. Also, the newer chainstay's bottom bracket clamps tighten around the bottom bracket shell instead of the much more fragile and sensitive bottom bracket bearing cups. That was a big improvement. I also swapped out the heavy, two-piece fiberglass seatpan that came with the V.2 for the lighter one-piece carbon fiber seatpan that came with the V20. From there, the rest of the V.2 and that first V20 are basically the same, meaning that you have more of a first generation V20 than a last generation V.2. The second picture shows my V.2/V20 in its final form, about to be replaced by my current V20c.
