ZVX3 Rivet Master Link (520 Pitch) (Gold)

Did not come with instructions but luckily I've done these before and the internet helped give the proper flare diameter of .224" - .236" for the 530 link. You need a proper tool for installation, including calipers to measure the flared pin. This is super critical, don't "eyeball it". Do it correctly and it will be safe and work properly for a long time. Currently have 40k on another chain done with a rivet link, still in great shape.

Fits and works perfectly with designed chain.
