Anyone have any experience with a Lynskey (looking at a level 2 or level 3). Anything good/bad to say about them.

Rear dropouts are spindly - not a lot of meat on them. Should be no issue unless a mishap occurs though (such as chain suck, stick in the chain, crash, ect). For some reason Lynskey went for bling in the dropout department at the expense of mishap durability.

I'm also not a fan of the model that uses the aero down tube. Tubes shaped this way don't like to flex vertically, which makes the ride rough, and at the same time they don't stiffen the bottom bracket as much as tubes that have the major axis oriented horizontally. Get the model with the biaxial down tube if you get a Lynskey.

Are you referring to the level 4 (aero downtube)

I don't know which model uses the aero down tube. The higher end frames I've seen photos of often use a large down tube that is vertical oval at the head tube and horizontal oval at the bottom bracket. This is a much better shape than the aero shape (tall vertical oval for full length of the down tube). My opinion of course.
