Serrai – Custom Gravel Bike

Our Custom Builds for Gravel Bikes

The Serrai is our custom gravel bike or cyclocross bike that’s designed and handmade specifically for each rider. Every custom Zinn frame is made one at a time by our veteran framebuilders with the highest level of quality you can find. Our precision welds and beautiful finishes are a testament to our dedication to quality. The Serrai can be built for hydraulic or cable disc brakes, with tire clearance for higher-volume gravel tires, and the Zinn Duro Carbon Fork. Whether you’re into racing cyclocross, long gravel grinder rides, or just recreational riding, we know how to create custom-fit bikes for gravel rides that will be comfortable and provide the performance you are seeking.

Custom fit on every Zinn Bike

Durability is super important on a gravel or ‘cross bike since vibration and shock are constantly affecting the frame. We build our custom gravel bikes with the proper balance of strength, durability, and lightness that integrates your specific needs. Designed with hand-picked tubing, proportional-length cranks, and our unique frame design, this is the perfect custom fit for gravel bikes. Whether under five feet tall or over seven, Zinn guarantees that your custom bike will fit perfectly.

Zinn Cycles Design Philosophy

Lennard Zinn has been designing and building custom gravel 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 and fit gravel bikes for cyclists who have suffered from injuries, reduced mobility, knee problems, back problems, neck problems, and many other ailments.

Proportional crank length is at the heart of all of our custom bike designs. We offer cranks from 130mm all the way 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 of the components will be proportional to the rider.

Fit, performance, comfort, and durability will all be superior on a Zinn bike than a bike from any other designer out there. We guarantee it.
