About ZTZ
Good parts. More riding.
A bike worth riding is a bike worth improving. ZTZ brings together suspension forks, hydraulic brakes, wheelsets, and practical accessories for the next step in your build.
We focus on what makes an upgrade worthwhile: the right fit, useful performance, and a price that makes sense. Whether you ride local trails, commute, or enjoy building your own bike, the choice should feel clear.
Performance with purpose
Choose useful control, comfort, braking, and rolling performance that match your riding plans and your budget.
Support that stays close
From your first compatibility question to help after a purchase, our team is available by email.
Start with the bike you love.
The idea behind ZTZ is simple. Choosing a replacement or upgrade should not mean decoding a confusing list of standards or paying for features you do not need.
We help riders focus on the details that change the decision: wheel size, axle and steerer standards, brake mounts, intended use, and the frame manufacturer's limits. The goal is a component that belongs on your bike, not just one that looks right in a photo.
That same practical approach carries through after you order. For a specification question, installation guidance, or help with an existing purchase, you can contact ZTZ directly.
