Trek Scratch 9 8 7 6 Air Coil Last pics of my Trek Scratch 9 Air before I traded it for a Session 88. HATED to let it go but I'll probably built up another one at some point. Last upgrade are the DT Swiss wheels all other specs listed on other pics. Easily the best Scratch build version I have experimented with. 170mm Fox F36 Float & 170mm rear travel Fox DHX Air 5.0
