Don't want to piss on your chips but there is a company out there making the exact same thing already: Rockguardz - Real Carbon Fibre MTB Rock Protectors
I've got one on my SL. They do mudguards as well but don't seem to have a model specific rear guard listed which is something I would be interested in for the SL
Ibis Mojo SL with DT Swiss XMC130 fork
Pace RC300 with Pace RC39 C-Type fork
Pace RC200F8 with Pace RC36 ProClass2 fork
- how were you able to release the fiberglass off the downtube without any mess nor breaking the mold itself?
- if i understand your pics correctly, you created the mold on top of the downtube, removed it and layed the fiber 'on top' of the mold you created?
