do you think there's a risk to break the frame and the fork without it?
no idea but i would carefully check those areas after each ride for cracks.
just to give you an idea: the Attitude rigid fork in that size weighs 610grams and the Adroit fork 560grams so they took away quite a bit of material.
Could this not be addressed with carbon wrapping?
I have a huge amount of this sitting in an old freezer. Cut to size, apply (already resined) and allow to air cool over a radiator or on low heat in oven.
Came from a mate working at a medical implants manufacturers and has been sat below freezing for about three years now whilst I consider making some brake boosters and other bits and bobs...!
If anyone thinks this would work I'll happily send you some over...
