Description

Zia Custom Triathlon Bicycle

The Zia is our custom triathlon bike or Time Trial bike. Fit and body position is the most critical aspect of a triathlon bike to achieve proper aerodynamics. For athletes who are either very tall or very short or have unusual proportions, a one size fits all triathlon bicycle will not work to get the proper fit and position.

The round tubing also enables us to install couplers on the bike so that you can travel around the world easily with your triathlon bike. Couplers are only available on steel and titanium versions of the Zia. We built The Zia with cable or hydraulic rim brakes and a tapered fork. When designing high-performance custom road bikes, we focus on the customer’s specific needs for fit and performance.

Lennard Zinn has been designing custom bikes for cyclists of all sizes for over 40 years. In that time, he has mastered the art of making a bike stronger and more durable than any other bike out there while keeping it light and responsive. The Zia TT bike is designed with your ideal crank length in mind so you can finally achieve the level of fit and performance you desire. The proportional length cranks, hand-picked tubing, and his unique compact frame design make this the perfect triathlon bicycle for all athletes.  

It does not matter if you are over seven feet tall or under five feet tall. We will build the perfect bike for you. Our Zia custom triathlon bike features cable routing for electronic shifting component groups and standard mechanical or wireless shifting systems. We can also build a crossover road and triathlon bike for those who participate in the occasional triathlon but mainly need a bike for everyday cycling and training. We also carry a non-custom titanium triathlon bike from our sister brand, Clydesdale bikes

Design

Zinn Cycles Design Philosophy

Lennard Zinn has been designing and building great bikes for big and tall cyclists, petite women, cyclists with injuries, and everyone else since 1982. He is one of the few bike designers in the world that has dedicated his career to improving the performance and durability of big and tall bikes and bikes for women. He has also spent a great deal of time working with Dr. Andy Pruitt to design bikes for cyclists who have suffered from injuries, reduced mobility, knee problems, back problems, neck problems, and many other ailments.

The difference between Zinn Cycles and others is the thought that goes into crafting each custom bike. It is not as simple as just scaling up a “normal” sized frame and calling it good. If all you do is scale, several things happen to the bike. 

If you only scale-up, the stretched-out tubes become less stiff, which results in high-speed frame shimmy. Shimmy is a dangerous by-product of a poorly designed bike. Second, the added material makes the bike heavier, especially if the builder tries to solve problem number one by just using thicker tubes. Third, without a fork with a long enough steering tube, the handlebars will be far too low for the tall cyclist, causing discomfort in the back, neck, wrists, and arms. Fourth, building a bike for a tall or small rider with average-length cranks will make the rider feel unnatural while pedaling.

A bike for big and tall riders needs to carefully consider the proportions of the riders to create a bike that works with the rider – not against. Proportional crank length is at the heart of our custom bike designs. We offer cranks from 130mm up to 220mm, so we can properly fit any person in the world, no matter their size. Lennard has developed great frame design concepts to address and solve all of these issues and more. 

A bike designed by Lennard Zinn will be stiff and strong while remaining lightweight. It will not shimmy at high speeds, and all components will be proportional to the rider. Fit, performance, comfort, and durability will all be superior on a Zinn bike compared to a bike from any other designer. We guarantee it.
