The 18mm stainless steel shackle is the largest and toughest available on market.
The shackle is CNC machined, from non-corrosive 304 stainless steel, which even in much smaller sections is very difficult to cut.
This design is ideal for expensive bikes that get locked up in the city for hours at a time.
RockyMounts supplies three keys.
