Stelvio – Custom Touring Bicycle

Titanium or Steel

The Stelvio is our custom touring bicycle. With incomparable durability, weight, and performance, this bike will be reliable for many miles of loaded touring. The Stelvio is fully custom, so we can include almost any feature you want. The base frame price includes rack and fender mounts, disc brake mounts, oversized head tube, and three water bottle cage mounts. Even though this is what we include on a standard basis, you can get your bike however you want. We can do cantilever or rim brakes, internally geared hubs, S&S couplers, internal routing for lights or electronic shifting, and anything else you can think of. Lennard Zinn has been designing custom bikes for cyclists of all sizes for over 30 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 Stelvio touring bike is designed for your ideal crank length so that you can finally achieve the level of fit and performance that you are looking for. The proportional length cranks, hand picked tubing, and Lennard’s unique compact frame design make this an unbeatable touring bike for any cycling adventure. It doesn’t matter if you are over seven feet tall or under five feet tall, this bike will be built perfectly for you. The Stelvio is available with custom cable routing for electronic shifting component groups, standard mechanical shifting systems, and also wireless shifting systems.

We offer a full service in-house bike fitting for those who can make it to Boulder, Colorado and we also have detailed measurements instructions for those who cannot make it out for an in-house fitting. We are also happy to work directly with a bike fitter in your area, and we offer upgraded 3D bike fittings with Dr. Andy Pruitt at the Boulder RETUL Center.


Zinn Cycles Design Philosophy

Lennard Zinn has been designing and building great bikes of all types for big and tall cyclists, small 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. There are many more factors to building a big and tall bike than most people understand. It is not as simple as just scaling up a “normal” sized frame and calling it good. When you do that, several things happen to the bike. First, the stretched-out tubes become less stiff, which results in high speed frame shimmy. This is a scary 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 with 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. 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.

Make it a Travel Bike

Add S&S Couplers for easy travel

If you want your bike to be a travel bike, we can add S&S couplings to your frame. If you choose titanium or steel for your frame material, couplers can easily be built into the frame, making it an incredible travel bike that breaks down into sections and fits into an airline regulation travel case. We can do two or four couplers depending on the size of your frame. Bigger bikes need four couplers and smaller bikes can get away with just two. S&S Couplers do not reduce the strength of the frame one bit, in fact, it’s quite the opposite. The Couplings are so well made that they become the strongest point in the tube! Not all bikes can fit completely into an airline regulation case. Bikes like 29ers, Touring bikes with racks and fenders, and e-bikes may or may not fit completely in the case and will require a secondary bag or case to carry some of the parts. Contact us about building your bike with couplers.
