Just try and stop yourself riding it......you won’t be able too....RIDE-RIDE-RIDE
What does it matter if you scratch it ..... it’s a mountain bike......ENJOY ?
I´ve invisiframed all of my bikes (I do some vinyl foil work as a side business as well) an the thing is that the film is insanely strong. The Xpell-foil is also self healing. If it scratches up, put hot water on it and it goes back to pristine.
I would say that it is close to a must on carbon bikes where damages can escalate. It takes a bit of concentration when you put it on, and you also have to do it in a heated room. If it´s to cold (sub 15c) you could be struggling with the adhesive.
