The subject line asks it all.
I have a 2008 QROO Lucero Titanium and it doesn’t fit it. The seatpost looks so damn close too but the system six seatpost is like 1/2 a centimeter too long. I was pretty upset after buying the seatpost 
Best you can do is take your bike to a QR retailer and ask if they can check it.
Dagnabbit! I called the local QR dealer who called his rep at QR and apparently they have two versions of this seatpost…one for carbon bikes and another for Ti bikes…I’ll let you know if it works.
The rumor was they did, but as noted it’s just a bit off… Tried it at the shop and it didn’t work (at least a Saber)
The official ones run $150 from LS now, I just checked for mine
Unfortunately, I had too many issus with my LS so when the wife said “you need to buy a new bike” I didn’t ask questions
