Ok, is has to be someone out there with a QR Lucero (or Caliente/Seduza) in size small (700c) that has a solution to fitting a waterbottle? Only way to even get anything on the frame is to use a bottle the size of a shotglass…
Don’t want to use the “bottle launchers” like X-wing… Last time I tried, my leg got caught on it and I did a nice headstand in transition… Great… 
So, any ideas or solutions?
I know that Bontrager now makes side exit bottle cages for this purpose. (they come in carbon too)
I have the same size bike. I had the profile carbon cages and replaced the seat tube cage with on of the cheaper plastice profle cages and can now fit one of the large water bottles there. i think the cage bolts to the bike a bit lower. It’s tight, but i can get the large on the seat tube and a smaller regular size bottle on the down tube. I also know that Profile is coming out with a pretty cool aero saddle mounted bottle holder that will work with the QR Lucero.
My girlfriend has small Lucero (with a custom pink shooting star paint job and pink sparkle laquer) and she uses the Arundel carbon side-loaders. She can get 750 in seat tube and the ‘odd’ kind of 600ml bottle (specialized one) on down tube. She does also run a profile bottle between her bars to dump aid station bottles into.
Do you have 650c or 700c? I have a S Seduza with 700c and don’t have problems. I use standard metal cages and can only put a 20oz bottle on the downtube, but I have two cages and two bottles.
