Product Analysis

Strictly select 6061 aluminum alloy
Loyal to the brand and strict selection
It is RISK's belief that we should go through many processing processes and create high quality products.
Simplicity! Fashion!
Built-in waterproof seal
RISK inserts a waterproof sealing ring on the edge of the bowl, and the storage design is lighter and more versatile!

Headset Cap(Stem Top Cap)
CNC technology, fine polishing, smooth surface!
Tips: We are paired with a better 304 stainless steel screw, not the ordinary 201 screw.
304 stainless steel is better, harder, stronger and bigger. The head has vertical stripes and no rust.
Even if it is a screw, RISK takes it seriously!
Steel flower screw,steel sheet thick, stronger locking force!
Vertical stripes real goods!
True 304 stainless steel handle cap screws
High strength, corrosion resistance, no rust!
