I've got a spare carbon triangle for a Scalpel 29er. This was taken off my medium 2013 Scalpel 29er 2 last year. The clear coat had a bubble in it and it flaked off so Halter's got me another one. This is 100% cosmetic. If I were to have ever needed it, I would have just thrown some frame protection over the area, but I haven't needed it so it's been sitting in my closet collecting dust.
