The screw is made of TC4 GR5 high-strength titanium alloy! It is lighter and safer!
Not stainless steel coated titanium, not aluminum alloy coated titanium.
Aluminum alloy Screw is cheaper & lighter, why we don't use it?
RISK has 6 years of experience in product development 2013-2019,and we know the importance of safety for riders! Even though AL screw is cheaper, we still use TC4 Srew,Cause it's much safer.
