I'm lost. I bought a used 2016 Plasma 5 in size Large. The "Large" sticker is even still on the frame.

My aero water bottle and rubber fairings rub mildly on the front wheel. The previous owner shaved a bit of material off of both the bottle and fairing to make the rub almost imperceptable. He said he thought there was a manufacturing defect in the bike/fork itself. I wasn't so sure.

I figured maybe he had put the XL bottle on the bike. Another poster here also has a size Large Plasma 5, and his water bottle measures (with a tape measure) about 1.5" shorter than mine. So maybe I have the wrong size?

So I ordered an entirely new large water bottle assembly, shipped from the UK, and it just arrived. It is the exact same size as the current bottle and obviously still rubs.

I now see that both bottles have a big "L" on the back of them. Grrrr.

So here is my question: if you have a size Large Plasma 5, can you look at the back of your water bottle and tell me if it is a "M" or "L"? Maybe something is going on here where the Large Plasma 5 takes the medium aero bottle?

There is just no way this should be rubbing.

Any help or advice will be appreciated.
